Abstract

Drug resistance, a major challenge in cancer chemotherapy, is a result of several mechanistic alterations including resistance to apoptosis. Apoptosis is a well-controlled cell death mechanism which is regulated by several signaling pathways. Alterations in structure, function, and expression pattern of the proteins involved in the regulation of apoptosis have been linked to drug resistance. Programmed Cell Death 10 (PDCD10) protein is recently associated with the regulation of cell survival and apoptosis. However, the role of PDCD10 in drug resistance has not been clearly established. Here, we aimed to figure out the role of PDCD10 in resistance to anti-cancer agents in different cell lines. We found that PDCD10 expression was cell- and anti-cancer agent-specific; down-regulated in doxorubicin- and docetaxel-resistant MCF7 cells while up-regulated in doxorubicin-resistant HeLa cells. Down-regulation of PDCD10 expression by siRNA in parental MCF7 cells increased the resistance while it increased sensitivity in doxorubicin-resistant HeLa cells. Similarly, over-expression of PDCD10 in parental HeLa cells increased the resistance to doxorubicin while it re-sensitized doxorubicin-resistant MCF7 cells. Moreover, the alterations in P...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
