(Submitter supplied) Diabetes is a risk factor for the development of cardiovascular diseases that are associated with impaired angiogenesis or increased endothelial cell apoptosis. Here is it shown that angiogenic repair of ischemic hind limbs was impaired in Lepr db/db mice, a leptin receptor deficient model of diabetes, compared to wild-type C57BL/6 (WT) mice as evaluated by laser Doppler flow and capillary density analyses. more...

(Submitter supplied) Experiment protocol: Experiment was performed on 10 to 15 weeks old male NMRI mice (Harlan, Holland) housed in standard conditions (temperature 22°C, humidity 60 ± 10 %, artificial light from 8.00 am to 8.00 pm, normally 5 animals per cage). Animals had free access to tap water and food pellets (R36, Labfor, Stockholm, Sweden). Animals were randomly divided into healthy and diabetic groups. The diabetic group received a single peritoneal injection of streptozotocin (STZ, Sigma-Aldrich, France, 180 mg/kg) dissolved in sodium citrate buffer solution (0.1 mol/l, pH 4.5) to induce experimental diabetes similar to type 1. more...

Analysis of experimental type 1 diabetic skeletal muscle subjected to endurance training. Diabetic muscle atrophy is accompanied by changes in the extracellular matrix (ECM). Results suggest the diabetes-induced decrease in gene expression of ECM proteins is partially attenuated by training.

(Submitter supplied) Purpose: The goal of this study was to compare the genome-wide promoter methylation alterations in macrophages and endothelial cells during hindlimb ischemia among normal, hyperlipidemic and type-2 diabetic mice. Methods: Unilateral hindlimb ischemia was induced by ligating femoral artery proximal to the bifurcation of superficial and deep femoral artery in mice deficient of LDL receptor and expressing only apolipoprotein B100 (LDLR-/-ApoB100/100, C57BL/6J background) (The Jackson Laboratory, Bar Harbor,USA) and mice with β-cell specific over-expression of insulin-like growth factor-2 in atherosclerotic background (IGF-II/LDLR-/-ApoB100/100, C57BL/6J background) with type 2 diabetic features on high-fat diet (TD 88173, Harlan Teklad: 42% of calories from fat and 0.15% from cholesterol, no sodium cholate) 8 weeks prior to surgery and continued throughout the study 1. more...

(Submitter supplied) Objective: To define the role of epigenetics, particularly DNA methylation in adaptive vascular growth in hyperlipidemic and type 2 diabetic mouse models of hind limb ischemia Methods: Unilateral hindlimb ischemia was induced by ligating femoral artery proximal to the bifurcation of superficial and deep femoral artery. DNA was isolated from ischemic muscles collected at day 7 after ischemia induction using DNeasy Tissue kit (Qiagen). more...

(Submitter supplied) Common acute injuries to skeletal muscle can lead to significant pain and disability. The current therapeutic approaches for treating muscle injuries are dependent on the clinical severity but not on the type of injury. The aim of this study was to compare the molecular events accompanying the degeneration and repair phases of contraction- and trauma-induced muscle injuries by applying DNA microarray methodology to two well-characterized mouse models of skeletal muscle injury, i.e., eccentric contraction-induced injury (CI) and traumatic injury induced by freezing (FI). more...

(Submitter supplied) Background: Lower-limb peripheral artery disease (PAD) is one of the major complications of diabetes mellitus. PAD is associated with poor limb and cardiovascular prognoses, along with a dramatic decrease in life expectancy. Despite major medical advances in the treatment of diabetes, a substantial therapeutic gap remains in the PAD population. Praliciguat is an orally available soluble guanylate cyclase (sGC) stimulator that has been reported both pre-clinically and in early-stage clinical trials to have favorable effects in metabolic and hemodynamic outcomes, suggesting that it may have a potential beneficial effect in PAD. more...
