Activation of human alpha1A-adrenergic receptors in PC12 cells causes many second messenger, mitogenic, and transcriptional responses. We examined the role of G protein activation in these responses by uncoupling the receptor through deletion of the first three amino acids from the third intracellular loop (Delta208-210). Expression levels of retrovirus-transfected wild-type and Delta(208-210) ...

Accurate assessment of prognosis of clear cell renal cell carcinoma (ccRCC) is key in optimizing management plans to fit individual patient needs. miRNAs are short noncoding single-stranded RNAs that control the expression of target genes and may act as cancer biomarkers. We analyzed the expression of miR-210 in 276 cases of primary ccRCC and compared its expression in 40 pairs of adjacent norm...

Hypoxia is a key component of the tumor microenvironment and represents a well-documented source of therapeutic failure in clinical oncology. Recent work has provided support for the idea that non-coding RNAs, and in particular, microRNAs, may play important roles in the adaptive response to low oxygen in tumors. Specifically, all published studies agree that the induction of microRNA-210 (miR-...

BACKGROUND In sub-Saharan Africa including South Africa, maternal mortality rates remain unacceptably high due to a shortage of registered nurses with advanced midwifery diplomas. OBJECTIVE To determine the profile of registered nurses (RNs) involved in maternity care in public referral hospitals of the Limpopo Province, South Africa. METHOD A cross-sectional descriptive study was conducted...

Maternal tobacco use in pregnancy increases the risk of neurodevelopmental disorders and neurobehavioral deficits in postnatal life. The present study tested the hypothesis that perinatal nicotine exposure exacerbated brain vulnerability to hypoxic-ischemic (HI) injury in neonatal rats through up-regulation of miR-210 expression in the developing brain. Nicotine was administered to pregnant rat...

OBJECTIVE To analyze the expression and clinical significance of miR-210 in patients with senile chronic obstructive pulmonary disease (COPD) complicating primary lung cancer. 30 cases of COPD PATIENTS AND METHODS: 30 cases of primary lung cancer and 30 cases of COPD complicating lung cancer were selected. MiR-210 can function as the cancer suppressor gene in progress from COPD to primary lung ...
