Nischarin-positive cells release fewer exosomes, and cell survival is decreased. J Clin Invest. 04/2011; 71(8 Supplement):2196-2196. Exosomes from Nischarin-Expressing Cells Reduce Breast Cancer Cell Motility and tumor growth, Cancer Research (2019). Knockdown of both nischarin and LKB1 enhanced cell migration, which was due to elevated PAK1 and LIMK1 (601329) phosphorylation. Jain P, Baranawal S, Alahari SK. We found that silencing Nischarin greatly promoted the motility of both rat and mouse derived neuronal cells, indicating that it is a negative regulator in neuronal migration. Co-culturing breast cancer cells with Nischarin-positive exosomes decreases tumor growth and lung metastasis. In humans, Nischarin is underexpressed in breast cancers. Suresh Alahari, professor of biochemistry and molecular biology at LSU Health New Orleans School of Medicine, discovered the protein, Nischarin. To confirm that Nischarin prevents cancer cell mi-gration, we performed a time course wound healing assay with our previously published MDA-MB-231 and. Cancer is most deadly when it metastasizes, and the investigators wanted to know how Nischarin was involved in this process. Carcinoma, Ductal, Breast Subject Areas on Research 14-3-3zeta Cooperates with ErbB2 to promote ductal carcinoma in situ progression to invasive breast cancer by inducing epithelial-mesenchymal transition. Developing tumor metastasis and invasion is the most important cause of. (Abstract) 9. Breast cancer is now the most frequently diagnosed cancer and leading cause of cancer death in women worldwide. Research conducted by Suresh Alahari, PhD, Professor of Biochemistry and Genetics at LSU Health New Orleans School of Medicine, has found that metformin, a commonly prescribed drug for Type 2 Diabetes, may be effective in treating cancers that lack a protein called Nischarin. Researchers at Louisiana State University found Nischarin, a novel. 04/2011; 71(8 Supplement):2196-2196. Alahari discovered Nischarin, a protein involved in many biological processes that also acts as a tumor suppressor. Nischarin is ubiquitously expressed, and encodes a novel cytoplasmic protein that inhibits Mapping of the gene for Nischarin, a Novel Integrin Binding. 1391 genes with high or low expression in HEK 293T relative to other cell lines from the BioGPS Cell Line Gene Expression Profiles dataset. Scott Cancer Center in the Clinical Sciences Research Building. Read "The β-catenin signaling pathway induces aggressive potential in breast cancer by up-regulating the chemokine CCL5, Experimental Cell Research" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. Nischarin expression levels from a microarray analysis of 286 breast cancer patients were averaged, and patients were then stratified either into the low-nischarin group (below mean expression, n = 158) or the high-nischarin group (above mean expression, n = 128). Exosomes from Nischarin-positive cells reduce breast cancer cell motility and adhesion, as well as tumor volume. Overexpression of Nischarin profoundly inhibits cell migration and invasion via altering actin. Co-culturing breast cancer cells with Nischarin-positive exosomes decreases tumor growth and lung metastasis. >Currently working in the areas of pre-clinical research and characterizing the molecular mechanism of novel targets for colon cancer stem cells. 11 (UPI) --A novel protein could hold the key for slowing or preventing the spread of breast cancer, new research suggests. Nischarin-positive cells release fewer exosomes, and cell survival is decreased. Angiogenesis inhibitors interfere in several ways with various steps in blood vessel growth. thailandcancerhelp. Characterization of tumor suppressor function of Nischarin in vitro and in vivo approaches using breast cancer cell lines. Expression of Nischarin negatively correlates with estrogen receptor and alters apoptosis, migration and invasion in human breast cancer. Radiation therapy can lower risk of breast cancer recurrence in patients with 'good risk' DCIS. 10 women from same family who all had breast cancer celebrate getting all-clear - Metro. Hrgovic, I. Carcinoma of Unknown Primary Site. These findings have added clinical significance because Nischarin expression is frequently reduced in human breast cancer, especially triple negative breast cancers, and is associated with reduced. The same cocultures formed xenograft tumors of significantly reduced volume following injection into mice. that Nischarin may affect anchorage independent growth as well as tumor growth in nude mice and thus Nischarin may be an important regulator of cancer progression. Much of his research on this novel protein has been in breast cancer. Co-culturing breast cancer cells with Nischarin-positive exosomes decreases tumor growth and lung metastasis. 7 percent of cancer deaths, according to the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. 766 proteins co-occuring with the tissue mda-mb-231 cell in abstracts of biomedical publications from the TISSUES Text-mining Tissue Protein Expression Evidence Scores dataset. Research studies have implicated nischarin in the regulation of invasion and metastasis of breast cancer (7,8). Alahari discovered Nischarin, a protein involved in many biological processes that also acts as a tumor suppressor.
