Cathepsins (CTSs) are multifunctional proteins that can play prominent roles in cancer progression and metastasis. In this systematic review, we compared the prognosis of CTS subtypes overexpression in leukemia and solid tumors, and investigated the effect of different factors on CTS prognosis. We systematically searched published articles indexed in PubMed, Scopus, Cochrane library, ISI Web of Science, and EmBase databases from February 2000 until January 2020. Among the selected leukemia and solid tumors studies, overexpression of CTS subtypes in newly diagnosed and treated patients were with poor prognosis in 43 studies (79.6%) and with good prognosis in 9 studies (16.6%). However, there were 2 studies (3.8%) with either good or poor prognosis, depending on conditions and caner stage and host cell. The relation between CTS and human leukocyte antigen (HLA) in leukemia and solid tumors was mentioned in 7 studies (13%). Overexpression of CTS subtypes in all new case patients had contributed to the induction of poor prognosis. It seems that CTS subtypes, based on the type of cancer and its stage, the type of host cells, and the probable relation with HLA, breed good or poor prognosis in patients with cancer. Therefore, monitoring the overexpression of CTS subtypes and determining the effect of each of these factors on CTS prognosis could be helpful in predicting cancer prognosis both in newly diagnosed or under treatment patients. They could also be useful in finding ways for improving the efficiency of contemporary therapeutic strategies in various types of leukemia and solid tumors. 相似文献

Cytotoxicity of umbelliprenin has been found in various cancer cell lines such as, prostate, breast, CLL, and skin. Encapsulating chemotherapeutic agents with nanoliposomes have been resulted in improved cytotoxicity effects than their free forms. However, whether nanoliposomal form of umbelliprenin could have higher cytotoxic effect than free umbelliprenin is not clarified yet. After synthesizing umbelliprenin, different concentrations (3, 6, 12, 25, 50, 100, 200 μg/ml) applied on the mouse mammary carcinoma cell line (4T1) for 24, 48, and 72 h at 37°C. Afterwards, the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was performed to analyze cytotoxicity. MTT assay results showed that IC50 of umbelliprenin in dimethyl sulfoxide (DMSO) (30.92, 30.64, and 62.23 for 24, 48, 72 h incubation, respectively) decreased (5.8, 5.0, 3.5 for 24, 48, 72 h incubation, respectively) when encapsulated with nanoliposomes. Nanoliposomal umbelliprenin cytotoxicity affected cell viability in concentration and time-dependent manner. Our study recommended nanoliposomal umbelliprenin as the most effective chemotherapeutic agent against the mouse mammary carcinoma cell line viability. Future in vivo studies and clinical trials are needed. 相似文献

Alzheimer's disease (AD) is a well‐known neurodegenerative disorder affecting millions of old people worldwide and the corresponding epidemiological data emphasize the importance of the disease. As AD is a multifactorial illness, various single target directed drugs that have reached clinical trials have failed. Therefore, various factors associated with outset of AD have been considered in targeted drug discovery. In this work, various benzochromenoquinolinones were synthesized and evaluated for their cholinesterase and BACE1 inhibitory activities as well as neuroprotective and metal‐chelating properties. Among the synthesized compounds, 14‐amino‐13‐(3‐nitrophenyl)‐2,3,4,13‐tetrahydro‐1H‐benzo[6,7]chromeno[2,3‐b]quinoline‐7,12‐dione ( 6m ) depicted the best inhibitory activity toward acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) with IC50s of 0.86 and 6.03 μm , respectively. Also, the compound could inhibit β‐secretase 1 (BACE1) with IC50=19.60 μm and showed metal chelating ability toward Cu2+, Fe2+, and Zn2+. In addition, docking study demonstrated desirable interactions of compound 6m with amino acid residues characterizing AChE, BChE, and BACE1. 相似文献

Combination therapy is a novel cancer therapy approach that combines two or more chemotherapy drugs. This treatment modality enhances the efficacy of chemotherapy by targeting key pathways in an additive or synergistic manner. Therefore, we investigated the efficacy of combination therapy by widely used chemotherapy drug doxorubicin (DOX) and oleanolic acid (OA) to induction of apoptosis for pancreatic cancer (PC) therapy. The effects of DOX, OA, and their combination (DOX-OA) were investigated on proliferation and viability of PC cell line (PANC-1) by MTT assay. Moreover, migration and invasion of the cancer cells were evaluated by trans-well migration assay and wound healing assay. Flow cytometry and DAPI (4′,6-diamidino-2-phenylindole) staining were employed to investigate apoptosis quantification and qualification of the treated cancer cells. Finally, mRNA expression of apoptosis-related genes was assessed by quantitative real-time polymerase chain reaction. Our results demonstrated that the proliferation and metastasis potential of PC cells significantly decreased after treatment by DOX, OA, and DOX-OA. Moreover, we observed an increase in apoptosis percentage in the treated cancer cells. The apoptosis-related gene expression was modified to increase the apoptosis rate in all of the treatment groups. However, the anticancer potency of DOX-OA combination was significantly more than that of DOX and OA treatments alone. Our study suggested that DOX-OA combination exerts more profound anticancer effects against PC cell lines than DOX or OA monotherapy. This approach may increase the efficiency of chemotherapy and reduce unintended side effects by lowering the prescribed dose of DOX. 相似文献
