Transcriptome analysis in a radiosensitive and a radioresistant cell line after ionizing radiation

ABSTRACT: Differential gene expression profiling was performed in two lymphoblastoid cell lines with different radiosentivitity, one radiosensitive (RS) and another radioresistant (RR), after different post-irradiation times. A greater and a prolonged transcriptional response after irradiation was induced in the RS cell line. Functional analysis showed that 24 h after irradiation genes involved in DNA damage response, negative regulation of the cell cycle and apoptosis were still differentially up-regulated in the RS cell line but not in the RR cell line. Sham-irradiated and irradiated (2 Gy) cell cultures of the RS and the RR cell line were incubated at 37ÂºC for 4 and 24 h and 14 days. After that, RNA was extracted and sequenced with QuantSeq technology

DNA copy number alteration analysis of radioresistant and radiosensitive prostate cancer cell lines

Project description:Prostate cancer cell lines DU145 and LNCaP were purchased from the American Type Culture Collection. Radioresistant (RR) sublines were generated form these original parental radiosensitive (RS) cell lines. aCGH profiles of radiosensitive (RS) and radioresistant (RR) prostate cancer cell lines were measured and compared to normal DNA.

Gene Expression data from human radioresistant and radiosensitive Nasopharyngeal Carcinoma Cells

Project description:Most of the NPC patients suffer from local recurrences and distant metastases within 1.5 years after radiotherapy due to radioresistance. Distinct patterns of gene expression and signatures were found in NPC, and have been used to associate them with cell proliferation, apoptosis, invasion and metastasis, but few gene expression profiling studies have been focused on the tumor radioresistance.We used gene expression microarray analyses to identify the difference of mRNA in radioresistant NPC CNE2-IR cells and radiosensitive CNE2 cells. Radioresistant subclone of nasopharyngeal carcinoma CNE2-IR cell line was cultured and produced according to the experienment schedule to undergo five rounds of sublethal dose of irradiation (11 Gy), and the parent cell line CNE2 cell line sensitive to radiotherapy as the control

Transcription profiling of human xenografted radioresistant and radiosensitive tumors before and after irradiation

Project description:Nu61, a radiation-resistant human tumor xenograft, was selected from a parental radiosensitive tumor SCC-61 by eight serial cycles of passage in athymic nude mice and in vivo irradiation. Obtained tumors were profiled using Affymetrix U133A arrays. Most abundant gene pattern associated with radioresistant phenotype was presented by IFN-inducible, Stat1-dependent pathway Experiment Overall Design: Obtained tumors were established as xenografts in nude mice. RNA were purified from each xenograft, normalized by concentration and used for hybridization with each array. Three arrays were used for each group (un-treated nu61 and SCC61 and irradiated nu61 and SCC61 5 and 24 hours post-IR). Each group contained from 5 animals; tumors were randomized by size and three tumors from each group were used for profiling

Interferon response of radioresistant and radiosensitive human head&neck tumor cell lines

Project description:Nu61, a radiation-resistant human tumor xenograft, was selected from a parental radiosensitive tumor SCC-61 by eight serial cycles of passage in athymic nude mice and in vivo irradiation. Obtained tumors xenografts were profiled in two independent experiments using Affymetrix U133A arrays. Most abundant gene pattern associated with radioresistant phenotype was presented by IFN-inducible, Stat1-dependent pathway. In these experiments we detected genes responding to IFN alpha, beta and gamma in nu61 and SCC61 Keywords: Pair-wise comparison of un-treated and treated tumor cell lines

Differentially expressed genes in radioresistant nasopharyngeal cancer cells

Project description:The NPC parental cell lines were seeded at a density of 1 x 105/T25 flask (30% to 40% confluency) in complete medium. After 24 hours of cell seeding, various doses from 6 to 14 Gy were administered to determine the sublethal dose for each cell line. The radiation was delivered at room temperature at 300 cGy/min with a linear accelerator (2100EX, Varian, VA, USA). To establish RR subclone, the NPC cells were received the sublethal dose of irradiation. After treatment, the surviving cells were selected and cultured to produce first generation of the subline cells. Again, the subline cells were received sublethal dose of irradiation and the surviving cells were cultured to produce next generation of the subline cells. Up to four generations of NPC cells were produced and defined the forth generation cells as RR subclone. Keywords: Parental vs. subclone cell line comparison
