Peroxisome proliferator-activated receptor gamma (PPAR gamma) agonists are commonly used to treat cardiovascular diseases, and are reported to have several effects on cardiovascular function that may be due to PPAR gamma-independent signaling events. Select angiotensin receptor blockers (ARBs) interact with and modulate PPAR gamma activity, thus we hypothesized that a PPAR gamma agonist may exert physiologic effects via the angiotensin II type 1(A) receptor (AT1(A)R). In AT1(A)R-overexpressing HEK 293 cells, both angiotensin II (Ang II) and the PPAR gamma agonist troglitazone (Trog) enhanced AT1(A)R internalization and recruitment of endogenous beta-arrestin 1/2 (beta arr1/2) to the AT1(A)R. A fluorescence assay to …

Background: Recent studies demonstrate that diverse antidepressant agents increase the cellular production of the nucleolipid CDP-diacylglycerol and its synthetic derivative, phosphatidylinositol, in depression-relevant brain regions. Pharmacological blockade of downstream phosphatidylinositide signaling disrupted the behavioral antidepressant effects in rats. However, the nucleolipid responses were resistant to inhibition by serotonin receptor antagonists, even though antidepressant-facilitated inositol phosphate accumulation was blocked. Could the neurochemical effects be additional to the known effects of the drugs on monoamine transmitter transporters? To examine this question, we tested selected agents in serotonin-depleted brain tissues, in PC12 cells devoid of serotonin transporters, and on the enzymatic activity of …

Vasomotor symptoms (VMS) are among the most bothersome complaints of postmenopausal women. To date, the most widely studied and effective treatment for VMS is hormone replacement therapy, consisting of estrogen (in women without a uterus) or estrogen plus progestin (in women with a uterus). Traditionally, oral estrogens have been used for treatment. However, over the years, additional estrogen formulations have been developed including transdermal patches; vaginal rings, creams, and tablets; and injectable preparations. Two newer formulations are transdermal estrogen spray and estradiol topical emulsion. This review evaluates the current literature assessing the use of these two newer formulations for the …
