Global cellular response to chemotherapy-induced apoptosis
How cancer cells globally struggle with a chemotherapeutic insult before succumbing to apoptosis is largely unknown. Here we use an integrated systems-level examination of transcription, translation, and proteolysis to understand these events central to cancer treatment. As a model we study myeloma cells exposed to the proteasome inhibitor bortezomib, a first-line therapy. Despite robust transc...
متن کاملChromatin-associated proteins HMGB1/2 and PDIA3 trigger cellular response to chemotherapy-induced DNA damage.
The identification of new molecular components of the DNA damage signaling cascade opens novel avenues to enhance the efficacy of chemotherapeutic drugs. High-mobility group protein 1 (HMGB1) is a DNA damage sensor responsive to the incorporation of nonnatural nucleosides into DNA; several nuclear and cytosolic proteins are functionally integrated with HMGB1 in the context of DNA damage respons...
متن کاملThe role of BRCA1 in the cellular response to chemotherapy.
Germline mutations of the BRCA1 gene account for approximately 5% of breast and ovarian cancer cases, and lower than normal BRCA1 expression or function may be an important contributing factor in sporadic cancers. The major role of BRCA1 is to respond to DNA damage by participating in cellular pathways for DNA repair, mRNA transcription, cell cycle regulation, and protein ubiquitination. Becaus...
متن کاملSTAT1: a modulator of chemotherapy-induced apoptosis.
The anthracyclines, such as doxorubicin, are widely used in the treatment of breast cancer. Previously, we showed that these drugs could activate the transcription factor, nuclear factor kappaB, in a DNA damage-dependent manner. We now show that these drugs can potentiate the activation of signal transducer and activator of transcription 1 (STAT1) in MDA-MB 435 breast cancer cells treated with ...
متن کاملCellular response to ionizing radiation: A microRNA story
MicroRNAs (miRNAs) represent a class of small non-coding RNA molecules that regulate gene expression at the post-transcriptional level. They play a crucial role in diverse cellular pathways. Ionizing radiation (IR) is one of the most important treatment protocols for patients that suffer from cancer and affects directly or indirectly cellular integration. Recently it has been discovered that mi...
