Cancer: Autophagy’s Role
Autophagy is a highly regulated, degradative process that mediates recycling of intracellular components to maintain Autophagy homeostasis or to promote survival under stressful conditions. conditions. The role of autophagy in cancer is multifaceted. On one hand, autophagy promotes promotes tumor cell survival in hypoxic environmen e nvironments ts or in response to cytotoxic therapies. On the other hand, deficits in autophagy in normal tissues can promote cancer initiation by genoto genotoxic xic stress caused by the accumulation of damaged cellular components and pro-inflammatory necrotic cells. Use EMD Millipore’s antibodies, small molecules, inhibitors and cell-based assays for elucidating autophagy mechanisms and identifying activators and inhibitors for this pathway of emerging importance.

Improper localization of LC3 control mutant. HT-1080 cells were transduced with GFP-LC3-G120A control mutant lentiviral particles (Catalogue No. 17-10189). GFP-LC3 displays a dif fuse distribution in both fed cells (A) and starved autophagic cells (B) with no translocation to a punctate cytoplasmic distribution as characteristic of wild-type LC3.

EMD Millipore’s newly released Anti-Anterior gradient protein 2 homolog (AGP2R), clone 7A10 monoclonal antibody has been published in a breast cancer biomarker study. In the D.L. Barraclough et al. paper entitled, The Metastasis-Associated Metastasis-Ass ociated Anterior Gradient 2 Protein Is Correlated with Poor Survival of Breast Cancer Patients** Patients UK cancer researchers, used the clone 7A10 antibody to correlate AGP2R protein expression in breast cancer tumor samples to prognosis. Until recently, recently, AGR2 had been independently reported to be associated with either reduced or increased survival of different groups of patients. This more extensive study with lengthy lengthy patient follow-ups reveals that the presence of AGR2 in the primary tumor was one of o f the most significant independent prognostic indicators in the study and is therefore a possible prognostic indicator of poor patient outcome in breast cancer. *Am. J. Pathol. (2009) 175:1848-1857.

Wang et al. from Albany Medical College report that MCF-7 breast cancer cells treated with NSC207895 show activation of p53, which results in the elevated expression of several proapoptotic genes. They also showed that NSC207895 works additively with Nutlin-3a to activate p53 and diminish the viability of cancer cells. * Mol. Cancer Ther. (2011) 10: 69-79.
