Research to advance cancer therapy
Share

New Orleans, LA – Research led by Suresh Alahari, PhD, the Fred Brazda Professor of Biochemistry and Molecular Biology at LSU Health New Orleans School of Medicine, has found a new role for a protein discovered by his lab in preventing the growth and spread of breast cancer. The results of the study, which could have a significant impact on cancer therapy, are published in the OnlineFirst section of the journal Cancer Research, available at http://cancerres.aacrjournals.org/content/early/2019/01/11/0008-5472.CAN-18-0842.

Dr. Alahari discovered the novel protein, Nischarin, which is involved in a number of biological processes including the regulation of breast cancer cell migration and movement. Although his lab has shown that Nischarin functions as a tumor suppressor, research continues to uncover new information that may lead to better treatments.

In the current study, the research team investigated Nischarin’s function in exosome release. Exosomes are nano-sized vesicles (fluid-filled sacs) containing proteins, genetic and other material involved in both physiological and pathological processes. Tumor-derived exosomes contain various signaling messengers for intercellular communication involved in tumor progression and metastasis of cancer. Tumor exosomes influence the interactions of various types of cells within the tumor microenvironment, regulating tumor development, progression and metastasis. Primary tumors release exosomes
