- Description:
- The formation of neuronal inclusions is one of the hallmarks of neurodegenerative diseases. These structures are composed of aggregated proteins, molecular chaperones, and components of the ubiquitin-proteasome system (UPS). Co-localization of aggregated proteins with cell-homeostasis maintaining machinery indicates that the cell may be failing in an attempt to clear these...

- Physiological linkage (i.e., the covariation of moment-to-moment physiology between individuals) is thought to play an important role in relationship functioning. The present study examined physiological linkage across interbeat interval (IBI) and skin conductance levels (SCL) in a sample of married spouses (N=106) during both a pleasant and a conflict conversation...

- Prostate cancer (PCa) is the most common non-cutaneous cancer among U.S. men. Lack of effective treatments for advanced disease make it a significant public health concern. However, PCa’s long natural history makes it an excellent target for prevention approaches that reduce overtreatment of indolent disease, treatment related morbidity, and mortality....

- Description:
- Some of the oldest drugs targeting metabolism are the antifolates such as aminopterin and methotrexate (MTX). MTX started being used in the 1950s to treat rheumatoid arthritis. Aminopterin and MTX both target one carbon metabolism and inhibit proliferation of cells. MTX was a potent inhibitor of inflammation, because it prevented...

- In the United States, allergic disease affects approximately 60 million people and impacts more people every year. While prevalence of allergic disease has steadily increased, there has concurrently been an increase in rates of metabolic syndrome—characterized by increased abdominal girth, decreased sensitivity to insulin, and higher levels of circulating blood...

- A prominent cause of premature ovarian insufficiency (POI) is gonadotoxic cancer therapies, which deplete the ovarian reserve of follicles, oocytes, and hormone-producing cells. Current fertility preservation methods include the removal and cryopreservation of ovarian tissue prior to gonadotoxic treatment. This cryopreserved tissue can be transplanted back and has been found...

Here, we used a CRISPR activation screen to identify genes that promote enzalutamide resistance in the metastatic castration-sensitive prostate cancer cell line LNCaP. We found that activation of the TGF-β target gene, PRRX2, promoted...
