BACKGROUND The effects of the anti-anginal drug fendiline on intracellular Ca2+ concentrations ([Ca2+]i) in human PC3 prostate cancer cells were examined. METHODS [Ca2+]i was measured using the fluorescent dye fura-2. RESULTS Fendiline (0.5-100 microM) increased [Ca2+]i in a concentration-dependent

Ranolazine, a piperazine derivative, is currently approved for the treatment of chronic angina. However, its ionic mechanisms in other types of cells remain unclear, although it is thought to be a selective blocker of late Na(+) current. This study was conducted to evaluate the possible effects of

The potassium channel activator nicorandil, under evaluation for antianginal management, has been shown to decrease neutrophil respiratory burst. Since our laboratory has demonstrated that reactive oxygen species (ROS) increase tumor necrosis factor (TNF) production, we hypothesized that nicorandil

Anti-invasive effects of riluzole and ranolazine, a neuro-protectant and an antianginal drug, respectively, on Mat-LyLu rat prostate cancer (PCa) cells were tested in vitro (i) at non-toxic doses and (ii) under both normoxic and hypoxic conditions, the latter common to growing tumours. Tetrodotoxin

BACKGROUND

Voltage-gated Na⁺ channels (VGSCs) are functionally upregulated in rat and human prostate cancer (PCa) where channel activity promotes cellular invasiveness in vitro and metastasis in vivo. Ranolazine is a clinically used VGSC inhibitor/anti-anginal drug,

BACKGROUND Human epidermal growth factor receptor HER3 has been implicated in promoting the aggressiveness and metastatic potential of breast cancer. Upregulation of HER3 has been found to be a major mechanism underlying drug resistance to EGFR and HER2 tyrosine kinase inhibitors and to endocrine

BACKGROUND Asymptomatic episodes of myocardial ischemia in clinically stable patients seem to occur frequently and may hint at a worse prognosis. OBJECTIVE This study was undertaken to determine whether surgical patients with coronary artery disease (CAD) have a higher risk of cardiac ischemia

BACKGROUND Platinum-based chemotherapeutic regimens, including BEP (bleomycin, etoposide, cisplatin) represent the standard of care, first line therapy in non-epithelial ovarian tumours. Cardiovascular toxicity is a rare adverse effect of bleomycin. METHODS A 41-year-old woman with ovarian granulosa

Modulating the metabolism by trimetazidine enhances myoblast differentiation and promotes myogenesis in cachectic tumor-bearing c26 mice.

Trimetazidine (TMZ) is a metabolic reprogramming agent able to partially inhibit mitochondrial free fatty acid β-oxidation while enhancing glucose oxidation. Here we have found that the metabolic shift driven by TMZ enhances the myogenic potential of skeletal muscle progenitor cells leading to MyoD,

Fluorouracil (5-FU), a commonly used anticancer agent, has potent cardiotoxicity that is mediated by vascular endothelial injury and vasospasm. Here, we report a patient demonstrating atrial fibrillation (AF), which was most likely induced by vasospasm mediated by 5-FU. A 69-year-old man presented

Sir James Black developed β-blockers, one of the most useful groups of drugs in use today. Not only are they being used for their original purpose to treat angina and cardiac arrhythmias, but they are also effective therapeutics for hypertension, cardiac failure, glaucoma, migraine and anxiety.

We have reported that anthracyclines and nonanthracycline chemotherapeutics caused diastolic dysfunction in cancer patients without cardiovascular risk factors. Diastolic dysfunction occurred as early as 1 week after the last chemotherapy cycle and manifested as impaired myocardial relaxation at

OBJECTIVE Continuous postoperative epidural analgesia with bupivacaine (BUP) and morphine (MS) may be associated with a decreased incidence of postoperative myocardial ischemia (ISCH) and infarction (MI). This study evaluated the incidence of ISCH and MI in patients with two or more risk factors for
