Renal vascular response to angiotensin 1-7 in rats: the role of Mas receptor

Research in Pharmaceutical Sciences, 2018
Recently a cross talk between angiotensin 1-7 (Ang1-7) receptor (MasR) and angiotensin II receptors types 1 and 2 (AT1R and AT2R) has been highlighted. The effects of MasR antagonist (A779) compared to the vehicle on the renal blood flow (RBF) and renal ...

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

Advanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Immunohistochemical detection of angiotensin receptors AT1 and AT2 in adrenal tumors.

Folia Histochemica et Cytobiologica, 2008
Angiotensin II is well known to affect the adrenal cell growth and function. Angiotensin receptors AT1 and AT2 were found to be present in the normal adrenal gland.

Desensitization of angiotensin receptor function

Kidney International, 1994
Angiotensin II is an eight amino acid peptide which plays a major role in the regulation of cardiovascular homeostasis. The physiologic effects of angiotensin (Ang) II are mediated by a G-protein coupled receptor, termed AT1, which activates phospholipase C.

Tumor‐Induced Splenic Remodeling: Mechanisms of Systemic Immunosuppression and Emerging Therapeutic Opportunities

Advanced Science, EarlyView.
ABSTRACT Despite the transformative impact of cancer immunotherapies such as immune checkpoint blockade, durable clinical responses remain limited. Increasing evidence indicates that antitumor immunity is governed not only by the tumor microenvironment, but also by systemic immune regulation mediated by peripheral immune organs. Among these, the spleen

The E3 Ligase RNF115 Aggravates Pathological Cardiac Hypertrophy via Ubiquitin‐Mediated Degradation of SPTBN1

Advanced Science, EarlyView.
In response to hypertrophic stimuli, increased c‑JUN phosphorylation upregulates RNF115, leading to SPTBN1 ubiquitination and degradation. which promotes F‑actin depolymerization and YAP activation, driving cardiac hypertrophy. The RNF115 inhibitor DTD effectively suppresses SPTBN1 ubiquitination and cardiac hypertrophy.

Role of Angiotensin Receptor Type I and Type II in the Development of Common Cardiac Problems

Journal of the Practice of Cardiovascular Sciences
The renin–angiotensin system is crucial for maintaining blood pressure and fluid balance. Central to this system are the angiotensin receptors, type I (AT1R) and type II (AT2R), which mediate the effects of angiotensin II (Ang-II).

Structural determinants for binding to angiotensin converting enzyme 2 (ACE2) and angiotensin receptors

Frontiers in Pharmacology, 2015
Angiotensin converting enzyme 2 (ACE2) is a zinc carboxypeptidase involved in the renin angiotensin system (RAS) and inactivates the potent vasopressive peptide angiotensin II (Ang II) by removing the C-terminal phenylalanine residue to yield Ang1-7 ...

Mechanical Activation of Piezo1 Drives Osteoarthritis Through Kdm5c‐Mediated Epigenetic Silencing

Advanced Science, EarlyView.
Excessive mechanical stress activates Piezo1, triggering Ca2+‐dependent cytoskeletal forces that deform the nucleus and reduce H3K4me3. Kdm5c demethylates H3K4me3 at Col2a1 and Runx3 promoters. Kdm5c knockout rescues degradation. Repurposed telmisartan directly inhibits Kdm5c, blocking this axis and showing disease‐modifying efficacy in mouse OA models
