Complementation of the radiosensitive M059J cell line

M059J is a radiosensitive cell line established from a human glioblastoma tumor that fails to express the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs, now known as PRKDC). Another cell line, M059K, established from the same tumor is radioresistant. Neither M059J nor M059K cells have been fully characterized, beyond the lack of expression of PRKDC and low expression of ATM in M059J cells. To determine whether its radiosensitive phenotype is due to a defect in the gene that encodes PRKDC, we show here that M059J cells can be complemented with the PRKDC gene by introducing a fragment of human chromosome 8 containing a copy of the human PRKDC gene. Two hybrid cell lines that retain an extra copy of PRKDC display active kinase activity and are radioresistant, demonstrating that the primary defect in M059J cells is in PRKDC. In addition, these cell lines derived from M059J cells provide us with a closer genetic match to M059J than M059K cells in studies to elucidate the function of DNA-PK.

Thermodynamic properties of an intramolecular DNA four-way junction

We have investigated the thermodynamic properties of two homologous DNA four-way junctions, J4 and J4M, based on 46-mer linear DNA molecules. J4 and J4M have the same base sequence with the only difference that the latter contains an uncharged methylene-acetal linkage, -O3'-CH2-O5', instead of the phosphodiester linkage, -O3'-PO2-O5'-, between the residues T18 and C19. The comparison of the thermal unfolding of the J4 junction and J4M junction serves to investigate the effect of the uncharged methylene-acetal linkage on the stability of the junction. Our analysis is based on CD, UV absorbance spectroscopy, DSC, and chemical footprinting. The aim is to characterize in detail the structure and stability of the junctions. As demonstrated before by NMR, in the presence of 5 mM MgCl2 +/- 50 mM NaCl, both J4 and J4M form a complete four-way junction. This is now evidenced by protection from OsO4 cleavage (chemical footprinting). We can assume that full base pairing occurs throughout the arms even at the center of the junction. CD spectra suggest that the helices within the junctions adopt the regular B-DNA conformation. Almost identical melting temperatures and unfolding enthalpies are obtained for J4 and J4M both by UV and DSC. Furthermore, the Van't Hoff enthalpy (DeltaHVH) derived from UV melting equals the calorimetric enthalpy (DeltaHcal), which means that the melting process of the structures proceeds in a two-state manner. All results taken together support the conclusion that there are no major conformational and energetic differences between J4 and J4M. The inclusion of the uncharged methylene-acetal group into the junction has no effect on its stability.

Root Penetration by Meloidogyne incognita Juveniles Infected with Bacillus Penetrans

Bacillus penetrans inhibited penetration by Meloidogyne incognita second-stage juveniles (J2) into tomato roots in the laboratory and greenhouse. Spores from this Florida population of B. penetrans attached to J2 of M. javanica, M. incognita, and M. arenaria. A greater proportion of J2 of M. javanica were infected than were J2 of either M. incognita or M. arenaria, and a greater number of spores attached to M. incognita than to M. arenaria.
