Su, JUDY Y., AND WILLIAM F. FRIEDMAN. Comparison of the responses of fetal and adult cardiac muscle to hypoxia. Am. J. Physiol. 224(6): 1249-1253. 1973.-The responses of cardiac tissue isolated from fetal and adult sheep were compared after selective inhibition of aerobic and anaerobic metabolism. The frequency of contraction of adult right atria was significantly more depressed by oxygen depri...

Glucose is one of the most important sources of cellular nutrition and glucose deprivation induces various cellular responses. In Schizosaccharomyces pombe, zinc finger protein Rst2 is activated upon glucose deprivation, and regulates gene expression via the STREP (stress response element of Schizosaccharomyces pombe) motif. However, the activation mechanism of Rst2 is not fully understood. We ...

To explore the molecular pathways underlying thiazolidinediones effects on pancreatic islets in conditions mimicking normo- and hyperglycemia, apoptosis rate and transcriptional response to Pioglitazone at both physiological and supraphysiological glucose concentrations were evaluated. Adult rat islets were cultured at physiological (5.6 mM) and supraphysiological (23 mM) glucose concentrations...

BACKGROUND AND AIMS Hypothermia provides neuroprotection after cardiac arrest, hypoxic-ischemic encephalopathy, and in animal models of ischemic stroke. However, as drug development for stroke has been beset by translational failure, we sought additional evidence that hypothermia protects human neurons against ischemic injury. METHODS Human embryonic stem cells were cultured and differentiate...

AbstractIn the present work we set out to investigate the neuroprotective effects of noscapine (0.5-2 µM) in presence of D-glucose on primary murine foetal cortical neurons after oxygen–glucose deprivation/24 hrs recovery. Cell viability, nitric oxide production and intracellular calcium ([ca2+]i) levels were evaluated by MTT assay, the modified Griess method and Fura-2 respectively. 25 and 100...

Oncogenic Kaposi’s sarcoma-associated herpesvirus (KSHV) is causally linked to several human cancers including Kaposi’s sarcoma and primary effusion lymphoma. Despite intensive studies, little is known about how KSHV alters cellular metabolism during cellular transformation. Using a novel model of KSHV-induced cellular transformation of primary rat embryonic metanephric mesenchymal stem cells (...

OBJECTIVE Pioglitazone, metformin, and gliclazide lower HbA(1c) and fasting plasma glucose in patients with type 2 diabetes. We compared the effects of these three drugs, used as monotherapy and in combination, on postload glycemia and composite insulin sensitivity index (CISI) in these patients. RESEARCH DESIGN AND METHODS Postload glycemia and CISI were analyzed for 940 patients who had ora...

Astrocytes are important for protecting neurons in the central nervous system. It has been reported that some antioxidants could protect astrocytes from ischemia/reperfusion-induced dysfunction. Cinnamtannin B-1 is a naturally occurring A-type proanthocyanidin that exhibits anti-oxidant properties. In this study, we investigated the effects of cinnamtannin B-1 on spinal cord astrocytes. Astrocy...
