This study was undertaken to elucidate whether and how autophagy was regulated in aldosterone (Aldo)-induced podocyte injury and to examine its role in this model both in vitro and in vivo. In cultured podocytes, Aldo increased autophagy flux as indicated by the enhanced expression of LC3-II/LC3-I and the reduction of p62. Autophagy induction with rapamycin (RP) provided a cytoprotective effect...
Aldosterone (ALDO) is a primary endogenous mineralocorticoid, appearing as the main hormone controlling sodium and water homeostasis. Its emerging role in the development of many organs has gained interest over the past few years. In the testis, Leydig cells contain mineralocorticoid receptors and ALDO stimulates androgen synthesis via the mineralocorticoid receptors in rat adult Leydig cells. ...
Interaction between aldosterone (Aldo) and angiotensin II (Ang II) in the cardiovascular system has been highlighted; however, its detailed signaling mechanism is poorly understood. Here, we examined the cross-talk of growth-promoting signaling between Aldo and Ang II in vascular smooth muscle cells (VSMC). Treatment with a lower dose of Aldo (10(-12) mol/L) and with a lower dose of Ang II (10(...
Previous studies have shown that preconditioning rats with a nonpressor dose of angiotensin II (Ang II) sensitizes the pressor response produced by later treatment with a higher dose of Ang II and that Ang II and aldosterone (Aldo) can modulate each other's pressor effects through actions involving the central nervous system. The current studies tested whether Aldo can cross-sensitize the press...
Aldosterone (Aldo) is a major sodium-retaining hormone that reduces renal sodium excretion and also stimulates sodium appetite. In the face of excess Aldo, the sodium-retaining action of this steroid is overridden by an adaptive regulatory mechanism, a phenomenon termed Aldo escape. The underlying mechanism of this phenomenon is not well defined but appeared to involve a number of natriuretic f...
The steroid hormone aldosterone (aldo) contributes to cardiovascular disease in animal models and in humans. Aldo activates the mineralocorticoid receptor (MR), a hormone-activated transcription factor, and indeed, pharmacological MR inhibition improves cardiovascular outcomes. Because the incidence of cardiovascular disease is lower in premenopausal women, we hypothesized that estrogen (E2) si...
According to general doctrine [1] canceroselectivity of Cyclophosphamide is based on different activities of the 4hydroxycyclophosphamide (OHCP) detoxifying cellular enzyme aldehyde dehydrogenase in tumor and normal cells. Aldehyde dehydrogenase converts the OHCP tautomere aldophosphamide (ALDO) to the non-cytotoxic carboxyphosphamide. Due to different activities of the detoxifying enzyme more ...
OBJECTIVES We hypothesized that the increased urinary Ca2+ and Mg2+ excretion and bone loss that accompanies aldosteronism is aggravated with furosemide and is attenuated by spironolactone. BACKGROUND Furosemide, a loop diuretic, is commonly used in patients with congestive heart failure (CHF), in which chronic, inappropriate (dietary Na+) elevations in plasma aldosterone (ALDO) and a catabol...
Aldosterone (ALDO) may induce cardiac hypertrophy by nonhemodynamic mechanisms that are not completely defined. Cardiotrophin-1 (CT-1) is a cytokine that exerts hypertrophic actions on isolated cardiomyocytes and promotes cardiac hypertrophy in vivo. We investigated whether ALDO induces CT-1 expression in HL-1 cardiomyocytes aiming at the possibility that the cytokine is involved in ALDO-induce...
BACKGROUND/AIM Aldosterone (Aldo), a mediator of kidney fibrosis, is implicated in the pathogenesis of chronic kidney diseases (CKD). The aim of this study was to evaluate the regulatory role of rapamycin (Rap) in Aldo-induced tubulointerstitial inflammation and fibrosis. METHODS Uninephrectomized, Sprague-Dawley rats were given 1% NaCl (salt) to drink and were randomized to receive treatment...
