A Study of Radiation-Induced Telomere Instability Using multiplex Ligation-Dependent Probe Amplification (mLPA)

引用

Advances in Biological Chemistry 2024年第3期14卷 73-85页

作者： Alan Chant Ahmad Chaudary christina m. Kraemer-Chant Department of microbiology and molecular Genetics University of Vermont Burlington VT USA Department of Public and Allied Health Bowling Green State University Bowling Green OH USA Department of Chemistry Saint Michaels College Colchester VT USA

The integrity of the chromosomes for two WIL2-derived lymphoblastoid cell lines (TK6 and WTK1) in the presence and absence of ionizing radiation was analyzed by multiplex Ligation-Dependent Probe Amplification (mLPA). The TK6 cell line has the native p53 tumor-suppressor gene, whereas WTK1 cells contain a p53 mutation. Each cell line was isolated pre- and post-irradiation (2 and 3 Gy) and analyzed by mLPA. The impact of irradiation on these two cell lines was investigated using probes that target specific regions on chromosomes associated with subtelomeric regions. Results indicate that WTK1 and TK6 are impacted differently after irradiation, and that each cell line presents its own unique mLPA profile. The most notable differences are the appearance of a number of probes in the post-irradiated mLPA profile that are not present in the controls, and two unique probe signals only seen in WTK1 cells. These results build on our previous studies that indicate how different human cell lines can be affected by radiation in significantly different ways depending on the presence or absence of wild type p53.

Androgen receptor(AR)is a major transcription factor that plays a role in inflammatory response including interleukin-6(IL6)signaling.1 While AR regulation through paracrine loop signaling in prostate tissue is well-studied,its impact through an IL6 autocrine loop in the lung has not been wellstudied despite the organ's response to respiratory viral *** inhibition and RNA knockdown of AR identified a bZIP transcription factor mAF to be a common target of inflammation using these perturbations in lung cells.
