Risk Evaluation of Proton Pump Inhibitors for Panitumumab-Related Hypomagnesemia in Patients with Metastatic Colorectal Cancer.

Hypomagnesemia commonly occurs as a side effect of panitumumab treatment. In severe cases, temporary discontinuation or dose reduction of panitumumab may be necessary. Proton pump inhibitors (PPIs) are reportedly potential risk factors for hypomagnesemia.

A novel selective androgen receptor modulator, NEP28, is efficacious in muscle and brain without serious side effects on prostate.

Age-related androgen depletion is known to be a risk factor for various diseases, such as osteoporosis and sarcopenia. Furthermore, recent studies have demonstrated that age-related androgen depletion results in accumulation of β-amyloid protein and thereby acts as a risk factor for the development of Alzheimer's disease. Supplemental androgen therapy has been shown to be efficacious in treating osteoporosis and sarcopenia.

XLGαolf regulates expression of p27Kip1 in a CSN5 and CDK2 dependent manner.

XLGα(olf) is an extra large transcriptional variant of the heterotrimeric G protein, Gα(olf), which we previously reported to be localized in the Golgi apparatus and interacted with Rab3A and Rab8A through its N-terminal region. However, many physiological functions of XLGα(olf) remain to be elucidated. In this study, performance of yeast two-hybrid screening with XLGα(olf) allowed isolation of COP9 signalosome subunit 5 (CSN5), known to regulate the p27(Kip1) protein level through a proteasome dependent pathway.
