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.

alphaB-crystallin is a novel predictor of resistance to neoadjuvant chemotherapy in breast cancer.

Aims: alphaB-crystallin is an anti-apoptotic protein commonly expressed in poor prognosis basal-like breast tumors, which are largely triple (estrogen receptor (ER), progesterone receptor (PR), and HER2) negative. We examined whether alphaB-crystallin expression in breast cancer was associated with a poor response to neoadjuvant (preoperative) chemotherapy.

Methods: One hundred and twelve breast cancer patients who received neoadjuvant chemotherapy and who had post-chemotherapy tumor specimens available for analysis were included in the study.

Reduction mammaplasty is a functional operation, improving quality of life in symptomatic women: a prospective, single-center breast reduction outcome study.

Breast hypertrophy creates a functional disability, adversely affecting quality of life because of disproportionate upper body weight. No study to date has prospectively shown or statistically proved (using validated questionnaires) the functional benefits of breast reduction surgery. Moreover, no study has quantified the physical findings seen in these patients.
