Human lung cancer cell lines in our laboratory: establishment of three large cell carcinoma cell lines and their biological characterization]

Three large cell carcinoma cell lines were established from tumors of lung cancer patients. The cell lines were named NUTLC-2, NUTLC-4 and NUTLC-5 and they were found to have the following biological characterization. 1) By chromosomal analysis, the tumor cells of two of the cell lines (NUTLC-2 and NUTLC-5) were human-origin cells. Numbers of chromosomes of these cells ranged from 52 to 59 in NUTLC-2 and from 68 to 75 in NUTLC-5, with the modal numbers of 56 and 71, respectively. 2) Primary tumor resected from the patient with lung cancer was heterotransplanted into the subcutis of a nude mouse. NUTLC-4 cell line was established in vitro from the tumor in nude mouse and the tumor cells were found to be mouse-origin cells by chromosomal analysis. Human DNA was not detected by Alu analysis. 3) The tumor cells of three cell lines could be heterotransplanted subcutaneously into nude mice. However, no natural distant metastasis in nude mouse was observed. 4) Drug sensitivity to NUTLC-2, NUTLC-4 and NUTLC-5 tumor cells differed individually according to MTT colorimetric assay, and characteristic drug sensitivity was not noted in histological types of lung cancer.

Characterization of a cell line (SW756) derived from a human squamous carcinoma of the uterine cervix

Summary An established cell line, SW756, derived from a primary squamous carcinoma of the uterine cervix is described by its morphology, ultrastructure, karyotype, genetic signature analysis, HLA typing, and tumorigenesis in the nude mouse. Cultured cells obtained from the SW756 derived nude mouse tumor also were studied for chromosome and isozyme markers. The original tumor was poorly differentiated carcinoma with minimal keratinization and is compared with that occurring in the nude mouse after the cultured cells were inoculated. The nude mouse tumor showed similar histological features, but better differentiation than the original tumor. Karyotype analysis of SW756 demonstrated a hyperdiploid stem line number and several marker chromosomes (MI-M6). No HeLa marker chromosomes were identified. The isozyme pattern for SW756 reported by others has been confirmed. The unique chromosome and isozyme features have been identified repeatedly in the cultured cells and, most importantly, in the post nude mouse culture. We recommend SW756 as a defined human tumorigenic cell line derived from a primary squamous carcinoma of the uterine cervix. This investigation was supported in part by Public Health Research Grant CA-06294 from the National Cancer Institute, Department of Health and Human Services.

A morphometric tool applied to angiogenesis research based on vessel segmentation

To investigate the relationship between P-glycoprotein (Pgp), glutathione S-transferase π (GST-π) and topoisomerase II (Topo II) expression and human gastric cancer chemoresistance in vitro. Primary single-cell suspensions were prepared from fresh specimens of primary gastric cancer and exposed to hydroxycamptothecin (HCPT), cisplatin (CDDP), 5-fluorouracil (5-FU), adriamycin (ADM) and mitomycin (MMC) for 48 h. Cell metabolic activity and rate of inhibition were evaluated using tetrazolium (MTT) assay. Pgp, GST-π and Topo II expression was determined in gastric carcinoma tissue samples using immunohistochemistry. Chemosensitivity of the gastric cancer cells varied; the rates of inhibition of cells exposed to HCPT, CDDP and 5-FU were significantly higher than that of cells exposed to ADM and MMC (p?相似文献   

The anti-tumor effect of cross-reacting material 197, an inhibitor of heparin-binding EGF-like growth factor, in human resistant ovarian cancer

Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a promising target for ovarian cancer therapy. Cross-reacting material 197 (CRM197), a specific HB-EGF inhibitor, has been proven to represent possible chemotherapeutic agent for ovarian cancer. However, the effect of CRM197 on the resistant ovarian carcinoma cells has not been sufficiently elucidated. Here, we found that HB-EGF was over-expressed in a paclitaxel-resistant human ovarian carcinoma cell line (A2780/Taxol) and a cisplatin-resistant cell line (A2780/CDDP), as well as the xenograft mouse tissue samples with these cells. To investigate the possible significance of the HB-EGF over-expression in A2780/Taxol and A2780/CDDP cells, we inhibited HB-EGF expression by CRM197 to investigate the effect of CRM197 treatment on these cells. We observed that CRM197 significantly induced anti-proliferative activity in a dose-dependent manner with the cell-cycle arrest at the G0/G1 phase and enhanced apoptosis in A2780/Taxol and A2780/CDDP cells. The sensitive ovarian carcinoma parental cell line (A2780), A2780/Taxol and A2780/CDDP cells formed tumors in nude mice, and enhanced tumorigenicity was observed in drug-resistant tumors. Furthermore, we observed that CRM197 significantly suppressed the growth of drug-resistant ovarian cancer xenografts in vivo (p<0.001). These results suggest that CRM197 as an HB-EGF-targeted agent has potent anti-tumor activity in paclitaxel- and cisplatin-resistant ovarian cancer which over-express HB-EGF.     

Endoscopic ultrasound-guided FNA biopsy of bile duct and gallbladder: analysis of 53 cases

OBJECTIVE: Endoscopic retrograde cholangiopancreaticography (ERCP)-guided brushing has been the standard of practice for surveillance and detection of carcinoma in the biliary tree. Few studies have evaluated the role of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in diagnosing clinically suspected cholangiocarcinoma. The role of this method in diagnosing clinically suspected gallbladder malignancies has not been extensively evaluated in the USA. This study investigates the role of EUS-FNA in the diagnosis of clinically suspected biliary tree and gallbladder malignancies in a large patient series. METHODS: EUS-FNAs were obtained from 46 bile duct and seven gallbladder lesions. On-site rapid interpretation was provided using air-dried Diff Quik stained smears. In addition, alcohol fixed Papanicoloau stained smears and Thin Prep preparations (Cytye Corp., Marlborough, MA, USA) were evaluated before providing a final cytological diagnosis. Tissue biopsies and/or clinical follow-up were used as the standards to determine operating characteristics for EUS-FNA. RESULTS: The mean ages for bile duct and gallbladder lesions were 66 years (range: 37-84 years), and 69 years (range 49-86 years), respectively. All cases diagnosed as suspicious/malignant on preliminary evaluation were confirmed on final cytological interpretation (27/27). The operating characteristics show that EUS-FNA is highly specific (100%) with sensitivity rates of 87% and 80% from clinically suspected malignancies of biliary tract and gallbladder, respectively. Sampling error in three cases and associated acute inflammation in two cases resulted in false-negative diagnoses. CONCLUSIONS: EUS-FNA of biliary tree and gallbladder carcinoma is highly specific and should be considered for evaluation of clinically suspicious lesions. Marked inflammation may result in false-negative diagnoses.     

Establishment and characterization of a human hepatocellular carcinoma cell line JHH-4

A human hepatocellular carcinoma cell line, JHH-4 was established from resected liver tumor. Morphological diagnosis of the original tumor was hepatocellular carcinoma, Edmondson type III. This cell line was composed of polygonal shaped cells. Subcellular organelle were observed in cytoplasm. Furthermore, bile canaliculi adhering junction was also remained at the cell surface. The growth rate of JHH-4 cell is slow, peaks of the chromosome number was 75 and 79, and plating efficiency was 3.0%. JHH-4 cell is transplantable to nude mouse. Furthermore, this cell line functionally synthesized and secreted human albumin, AFP and other proteins in vitro.     

Rates of micronuclei induction in different mouse strains

It has previously been shown that the inbred mouse strain MS/Ae was more sensitive in the micronucleus test to several mutagenic agents than outbred mice. To elucidate the possible influence of inbreeding, several inbred strains including MS/Ae, AKR, BALB/c, C57 BR were compared to the two OF1 and NMRI outbred strains. The 3 mutagenic agents MNNG, MMC and MMS all induced a significantly higher number of micronuclei in the MS/Ae strain than in any of the other mouse strains. AKR was especially resistant to the alkylating agents MMS and MNNG. Hence, except for the MS/Ae mouse strain, no inbred strain showed a systematically higher sensitivity than the outbred strains for all of the 3 mutagenic agents used.     

Intraductal polypoid growth variant of pancreatic acinar cell carcinoma metastasizing to the intrahepatic bile duct 6 years after surgery: a case report and literature review

We present the first reported case of intraductal polypoid growth (IPG) variant of pancreatic acinar cell carcinoma (ACC) metastasizing to the intrahepatic bile duct. A 58-year-old Japanese woman had previously presented with obstructive jaundice and a 7.0 cm mass in the pancreatic head. She underwent biliary drainage for 2 months followed by pancreatectomy. Histological examination revealed a carcinoma with acinar pattern, immunohistochemically positive for trypsin, and acinar cell carcinoma was diagnosed. IPGs were prominent in the main pancreatic duct and its tributaries, extending into the intrapancreatic bile duct with tumor casts in the lumen. Imaging examinations 6 years later revealed a growing lesion within the intrahepatic bile duct. Needle biopsy examination suggested metastasis of ACC, and she underwent chemoradiation therapy and partial hepatectomy. Histological examination demonstrated ACC confined to the intrahepatic bile duct. The localization of metastasis and slow growth may indicate indolent biologic behavior of the IPG variant.     

Dual Phosphoinositide 3-Kinase/Mammalian Target of Rapamycin Inhibitor NVP-BEZ235 Has a Therapeutic Potential and Sensitizes Cisplatin in Nasopharyngeal Carcinoma

Phosphoinositide 3-kinase (PI3K)/AKT/mammalian target of rapamycin inhibitor (mTOR) pathway is often constitutively activated in human tumor cells and thus has been considered as a promising drug target. To ascertain a therapeutical approach of nasopharyngeal carcinoma (NPC), we hypothesized NVP-BEZ235, a novel and potent imidazo[4,5-c] quinolone derivative, that dually inhibits both PI3K and mTOR kinases activities, had antitumor activity in NPC. Expectedly, we found that NVP-BEZ235 selectively inhibited proliferation of NPC cells rather than normal nasopharyngeal cells using MTT assay. In NPC cell lines, with the extended exposure, NVP-BEZ235 selectively inhibited proliferation of NPC cells harboring PIK3CA mutation, compared to cells with wild-type PIK3CA. Furthermore, exposure of NPC cells to NVP-BEZ235 resulted in G1 growth arrest by Propidium iodide uptake assay, reduction of cyclin D1and CDK4, and increased levels of P27 and P21 by Western blotting, but negligible apoptosis. Moreover, we found that cisplatin (CDDP) activated PI3K/AKT and mTORC1 pathways and NVP-BEZ235 alleviated the activation by CDDP through dually targeting PI3K and mTOR kinases. Also, NVP-BEZ235 combining with CDDP synergistically inhibited proliferation and induced apoptosis in NPC cells. In CNE2 and HONE1 nude mice xenograft models, orally NVP-BEZ235 efficiently attenuated tumor growth with no obvious toxicity. In combination with NVP-BEZ235 and CDDP, there was dramatic synergy in shrinking tumor volumes and inducing apoptosis through increasing Noxa, Bax and decreasing Mcl-1, Bcl-2. Based on the above results, NVP-BEZ235, which has entered phase I/II clinical trials in patients with advanced solid tumors, has a potential as a monotherapy or in combination with CDDP for NPC treatment.     

Establishment and characterization of EB virus-free normal B-lymphocyte and interleukin-6-producing poorly differentiated adenocarcinoma cell lines derived from gastric tumor tissue

We successfully established two cell lines, an adenocarcinoma cell line (designated as HIGS) and Epstein-Barr virus-free normal B-lymphocyte cell line (designated as HIGS-BL), derived from a moderately to poorly differentiated adenocarcinoma of the stomach, and examined their characteristics. The tumor delivered to our laboratory from an operating room was cut into small pieces and cultured on the dishes. HIGS and HIGS-BL were established from each individual dish after the onset of primary culture. Although their culture methods were the same, the HIGS cell line was not established from the dishes growing HIGS-BL cells. In addition, HIGS-BL cells were scarcely observed in the HIGS cell dishes. Because of these factors, we have considered until now that HIGS-BL cells may inhibit the growth of HIGS cells or cause damage to HIGS cells by unknown mechanisms. Injection of HIGS-BL cells, other B-lymphocyte cell lines, or the conditioned media of HIGS-BL cells into nude mice bearing HIGS-grafted tumors was performed individually. When HIGS and HIGS-BL cells were co-cultured in the same dishes, HIGS-BL cells inhibited the proliferation of HIGS cells. The inhibition of grafted tumor growth was confirmed by the injection of not only the HIGS-BL cells but also the B-lymphocytes. Furthermore, this inhibition was only observed when the conditioned medium of B-lymphocytes was injected into the nude mice. These results suggested that the secretory products by general B-lymphocytes (including HIGS-BL) have some ability to inhibit the proliferation of HIGS cells. In addition, susceptibility tests to anti-cancer drugs suggested that HIGS cells were sensitive to CDDP, ADM and MMC, and HIGS-BL cells were sensitive to CDDP. If CDDP was used for chemotherapy in the patient, the drug produced atrophy of HIGS-BL cells. The study about HIGS and HIGS-BL cells reported the necessity for novel therapeutic approaches in oncotherapy.     

Establishment and characterization of human cholaginocarcinoma, MEC, producing carbohydrate antigen 19-9

A new tumor cell line MEC was established from pleural effusion of a patient of cholaginocarcinoma. In tissue culture, the cell line grew in the sheet of variant cells and showed the epithelial-like pattern. Histologically, the cell line almost showed the same pattern as those in bile and preural effusion from the patient. Electron microscopic observation of this cell line showed the irregular microvilli on the surface of the cell and the desmosome between cells. The doubling time of the cell line was 40.8 hours. Chromosome counts ranged from 61 to 86. The cell line had 9 marker chromosomes and some variant chromosomes. The cell line was transplanted into the subcutaneous of nude mice and formed the tumor. It showed the moderately differentiated tubular adenocarcinoma the same pattern as the primary tumor. We have recognized the producing and releasing of CA19-9 in the serum from the tumor bearing nude mouse and supernate of the medium as the serum from the patient. The presentation of CA19-9 in the cytosol of the cell line and the tumor cells of nude mouse was recognized in Avidin-Biotin-Peroxidase Complex in immunoloperoxidase techniques. The cell line can grow in serum-free medium. On September, 1990, the cell line has been maintained from 70 passages during about 800 days.     

Complete Radiofrequency Ablation of Hepatolithiasis-Associated Cholangiocarcinoma and Successful Management of Post-ablation Bronchobiliary Fistula

This report documented the use of radiofrequency ablation (RFA) in the treatment of hepatolithiasis-associated cholangiocarcinoma and cyanoacrylate glue in the management of post-ablation bronchobiliary fistula. A 47-year-old Chinese woman with 20 years history of extrahepatic and intrahepatic cholangiolithiasis and multiple hepatic segmentectomy, developed hepatolithiasis-associated cholangiocarcinoma. The tumor was successfully treated with RFA but patient developed bronchobiliary fistula. Cyanoacrylate glue was used for occluding the bronchobiliary fistula. CT scan at 3 months showed complete restoration of physiological separation between the biliary and bronchial system. Repeat CT scan showed complete tumor ablation with no signs of tumor recurrence 10 months after RFA. In conclusion, RFA may be a safe and effective treatment option for patients with hepatolithiasis-associated cholangiocarcinoma who are poor candidates for surgical resection. Protection of the integrity of the bile duct and diaphragm during RFA can minimize postoperative complications. In case of development of post-ablation bronchobiliary fistula, cyanoacrylate glue can be used to occlude the fistula, before surgical resection is considered.
