Post-SSRI Sexual Dysfunction (PSSD): Biological Plausibility, Symptoms, Diagnosis, and Presumed Risk Factors.

Introduction: Post-SSRI sexual-dysfunction (PSSD) is an iatrogenic syndrome, the underlying neurobiological mechanisms of which are unclear. Symptom onset follows cessation of serotonergic antidepressants i.e.

Filamin A is a novel caveolin-1-dependent target in IGF-I-stimulated cancer cell migration.

Caveolin-1 is an essential structural constituent of caveolae which is involved in regulation of mitogenic signaling and oncogenesis. Caveolin-1 has been implicated in cell migration but its exact role and mechanism of action in this process remained obscure. We have previously reported that expression of caveolin-1 in stably transfected MCF-7 human breast cancer (MCF-7/Cav1) cells up-regulates phosphorylation of a putative Akt substrate protein, designated pp340 [D.

Cancer multidrug resistance: a review of recent drug discovery research.

Conventional cancer chemotherapy is seriously limited by tumor cells exhibiting multidrug resistance (MDR), caused by changes in the level or activity of membrane transporters that mediate energy-dependent drug efflux and of other proteins that affect drug metabolism and/or drug action. Many inhibitors of MDR transporters have been identified and some are undergoing clinical trials, but currently none are in clinical use. Here we briefly review the status of MDR drugs, outline novel approaches designed to suppress or circumvent MDR mechanisms and discuss the future of MDR therapy in oncology.
