Diagnostic Assay for Determining Patient Response to Apoptosis-related Cancer Therapy
Abstract: Many known chemotherapeutic drugs kill abnormal cells through a process called apoptosis. Bcl-2 proteins are negative regulators of apoptosis that control cell survival and death. Increased expression of anti-apoptotic Bcl-2 proteins commonly occurs in up to 30% of all cancers, providing cancer cells a pro-survival advantage to evade cell...
