Salubrinal Exposes Anticancer Properties in Inflammatory Breast Cancer Cells by Manipulating the Endoplasmic Reticulum Stress Pathway.

The endoplasmic reticulum (ER) regulates protein folding, post-translational modifications, lipid synthesis, and calcium signaling to attenuate the accumulation of misfolded proteins causing ER stress and maintains cellular homeostasis. The tumor microenvironment is rich in soluble cytokines, chemokines, growth, and angiogenic factors and can drive the ER's abnormal functioning in healthy cells. Cancer cells adapt well to the tumor microenvironment induced ER stress.

Cholesteryl Ester Transfer Protein Inhibitors: Trials and Tribulations.

The cholesteryl ester transfer protein (CETP) is a plasma protein that plays an important role in the transfer of lipids between plasma lipoproteins. The CETP inhibitors have been widely studied as a pharmacologic therapy to target plasma cholesterol in order to reduce the risk of atherosclerotic cardiovascular disease . Using CETP inhibitors as cholesterol modifiers was based on the genetic research that found correlations between CETP activity and cholesterol levels.
