Description: The New Investigators Committee (NIC) of the International Society of Hypertension (ISH) is a dynamic group of junior doctors and scientists, actively involved in various society activities. This report highlights the events (scientific meetings and summer schools) and activities (social media, mentorship and networking) during 2019 including May Measurement Month and collaborative efforts with the ISH Women in Hypertension Research Committee (WiHRC). The ISH NIC is proud to sponsor awards for outstanding work by junior and emerging researchers at hypertension conferences and also provides opportunities to showcase their work on our social media features such as 'Our Fellows Work' and the New Investigator Spotlight of the month. In 2020, the ISH NIC aims to promote women in leadership roles and to foster strong collaborations with and between society committees and other scientific organizations.

Description: Cardiovascular disease, including cardiac hypertrophy, is common in patients with kidney disease and can be partially attenuated using blockers of the renin-angiotensin system (RAS). It is unknown whether cardiac microRNAs contribute to the pathogenesis of cardiac hypertrophy or to the protective effect of RAS blockade in kidney disease. Using a subtotal nephrectomy rat model of kidney injury, we investigated changes in cardiac microRNAs that are known to have direct target genes involved in the regulation of apoptosis, fibrosis, and hypertrophy. The effect of treatment with the angiotensin-converting enzyme (ACE) inhibitor ramipril on cardiac microRNAs was also investigated. Kidney injury led to a significant increase in cardiac microRNA-212 and mi- croRNA-132 expression. Ramipril reduced cardiac hypertrophy, attenuated the increase in microRNA-212 and microRNA-132, and significantly increased microRNA-133 and microRNA-1 expression. There was altered expression of caspase-9, B cell lymphoma-2, transforming growth factor-Î², fibronectin 1, collagen type 1A1, and forkhead box protein O3, which are all known to be involved in the regulation of apoptosis, fibrosis, and hypertrophy in cardiac cells while being targets for the above microRNAs. ACE inhibitor treatment increased expression of microRNA-133 and microRNA-1. The inhibitory action of ACE inhibitor treatment on increased cardiac NADPH oxidase isoform 1 expression after subtotal nephrectomy surgery suggests that inhibition of oxidative stress is also one of mechanism of ACE inhibitor-mediated cardioprotection. These finding suggests the involvement of microRNAs in the cardioprotective action of ACE inhibition in acute renal injury, which is mediated through an inhibitory action on profibrotic and proapoptotic target genes and stimulatory action on antihypertrophic and antiapoptotic target genes. © 2015 the American Physiological Society.
