Neuregulin-1 attenuates stress-induced vascular senescence

The PAI-1 Antagonist TM5441 Attenuates L-NAME-Induced Hypertension and Vascular Senescence

Vaccine-induced inflammation attenuates the vascular responses to mental stress.

Inflammation is associated with poorer vascular function, with evidence to suggest that inflammation can also impair the vascular responses to mental stress. This study examined the effects of vaccine-induced inflammation on vascular responses to mental stress in healthy participants. Eighteen male participants completed two stress sessions: an inflammation condition having received a typhoid v...

PTTG1 Attenuates Drug-Induced Cellular Senescence

As PTTG1 (pituitary tumor transforming gene) abundance correlates with adverse outcomes in cancer treatment, we determined mechanisms underlying this observation by assessing the role of PTTG1 in regulating cell response to anti-neoplastic drugs. HCT116 cells devoid of PTTG1 (PTTG1(-/-)) exhibited enhanced drug sensitivity as assessed by measuring BrdU incorporation in vitro. Apoptosis, mitosis...

Plasminogen activator inhibitor-1 antagonist TM5441 attenuates Nω-nitro-L-arginine methyl ester-induced hypertension and vascular senescence.

BACKGROUND Long-term inhibition of nitric oxide synthase by L-arginine analogues such as N(ω)-nitro-l-arginine methyl ester (L-NAME) has been shown to induce senescence in vitro and systemic hypertension and arteriosclerosis in vivo. We previously reported that plasminogen activator inhibitor-1 (PAI-1)-deficient mice (PAI-1(-/-)) are protected against L-NAME-induced pathologies. In this study, ...

Diosgenin attenuates cardiac oxidative stress in streptozotocin- induced diabetic rat

Background and Objective: Chronic diabetes mellitus (DM) leads to cardiovascular dysfunction. Diosgenin is a natural steroidal saponin with cardiovascular protective potential. In this research study, the beneficial effect of diosgenin was evaluated on some markers of oxidative stress in cardia tissue of streptozotocin (STZ)-diabetic rats. Materials and Methods: Male Wistar rats (n = 28) were ...
