Gal-3 does not suppress cisplatin-induced apoptosis in A-375 melanoma cells

Abstract

Melanoma is the most aggressive of all skin cancers and is exceptionally resistant to therapies. During melanoma progression, cancer cells reprogram their proliferation and survival pathways and achieve resistance to treatment-induced apoptosis. Galectin-3 (gal-3) is a member of the lectin family and is involved in such biological processes as cell adhesion, growth and differentiation, the cell cycle, and apoptosis. Gal-3 also plays an important role in tumor development and metastasis. The relationship between gal-3 expression and these processes is specific to the tumor type and the stage of cancer progression. The biological functions of gal-3 depend on its localization in the cell. In the present study, human metastatic melanoma A-375 cells, characterized by weak endogenous expression of gal-3, were transfected with gal-3 cDNA and cisplatin-induced apoptosis was measured. Data from AnnexinV and mitochondrial membrane potential analysis revealed that gal-3 did not protect the A-375 melanoma cells against cisplatin. This result probably is associated with its nuclear localization in the cells.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

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.

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
