Despite significant advances in combinations of radiotherapy and chemotherapy, altered fractionation schedules and image-guided radiotherapy, many cancer patients fail to benefit from radiation. A prevailing hypothesis is that targeting repair of DNA double strand breaks (DSBs) can enhance radiation effects in the tumor and overcome therapeutic resistance without incurring off-target toxicities. Unrepaired DSBs can block cancer cell proliferation, promote cancer cell death and induce cellular senescence. Given the slow progress to date translating novel DSB repair inhibitors as radiosensitizers, we have explored drug repurposing, a proven route to improving speed, costs and success rates of drug development...

Atrial remodeling is considered to be any persistent change in atrial structure or function, and is responsible for the development and perpetuation of atrial fibrillation (AF). Oxidative stress and intracellular pH regulation may also be linked to AF; however it remains unclear whether eicosapentaenoic acid (EPA) or statins have beneficial therapeutic effects. The aim of the present study was to investigate the effects of EPA and pitavastatin on the electrophysiology of and gene expressions in mice with rapidly-paced atria...

There are many speculations about the safety of statins which are widely used drugs. In contrast, statins are safer than many widely used drugs. Rhabdomyolysis, the most important adverse event is closely related to plasma drug levels which take drug interactions into account. The most important drugs among interacting drugs are fibrates, antiretroviral drugs and macrolid antibiotics, and, pitavastatin seems to be more advantageous than other statins. Similarly, pitavastatin has better myopathy profile when compared to other statins...

Managing dyslipidaemia is central to the management of cardiovascular disease. Statins are the cornerstone of cardiovascular prevention for general population, and in patients with type 2 diabetes mellitus. However, statin therapy predisposes to type 2 diabetes, particularly in patients with predisposition to this condition. Some statins have been associated with increases in blood glucose in patients, and others have shown to have neutral effects, varying from one another their glucose or diabetogenic capacity...

HMG-CoA reductase inhibitors (statins) represent the most effective class of LDL lowering drugs with an overall positive safety and tolerability profile. They have also consistent benefit in terms of reduced cardiovascular (CV) events in both primary and secondary prevention. Pitavastatin is a new member of the statin class. This review provides a current overview of pravastatin's role in CV risk reduction. In brief pitatastatin has pleitrophic effects as the other statins. It has been shown that it reduces plaque atheroma volume in acute coranary settings...

Epidemiological studies have shown that low HDL predicts cardiovascular risk just as much as elevated LDL cholesterol levels. However, today we know that HDL functionality is more important than HDL levels. As a group effect, statins increase HDL levels. They are also thought to increase functional HDL. Pitavastatin is a new statin with a different structure, shown to increase HDL levels more than other statins as well as functionality. Studies have shown that plaque regression occurs with pitavastatin. These findings provide the expectation that it will also decrease cardiovascular events...

In short-term, phase III or IV studies in Asian and European patients, pitavastatin 1, 2 and 4 mg once daily reduced LDL-Cholesterol (LDL-C) 34%, 42% and 47%, respectively. Pitavastatin provided sustained LDL-C-lowering efficacy over up to 60 weeks' therapy in extension studies. In comparative studies pitavastatin 4 mg and simvastatin 40 mg reduced LDL-C similarly, reduction in triglycerides and increase in HDL-Cholesterol (HDL-C) was more prominent with pitavastatin. In comparative studies with atorvastatin, pitavastatin 4mg was found to be more effective than 20 mg of atorvastatin, and a little less effective than 40 mg of atorvastatin...

Prenylation is a posttranslational lipid modification required for the proper functions of a number of proteins involved in cell regulation. Here, we show that prenylation inhibition is important for renal cell carcinoma (RCC) growth, survival and response to chemotherapy, and its underlying mechanism may be contributed to mitochondrial dysfunction. We first demonstrated that a HMG-CoA reductase inhibitor pitavastatin inhibited mevalonate pathway and thereby prenylation in RCC cells. In addition, pitavastatin is effective in inhibiting growth and inducing apoptosis in a panel of RCC cell lines...

OBJECTIVES: The aim of the present study was to assess the effect of early statin therapy on fibrous-cap thickness in coronary plaques of patients with acute coronary syndrome (ACS) by using optical coherence tomography. BACKGROUND: Statins can contribute to the stabilization of coronary plaques. METHODS: This is a prospective, randomized, active-controlled, single-center study. Patients with ACS and untreated dyslipidemia were enrolled and randomly allocated (ratio 1:1) to either the early statin group (received pitavastatin 4 mg/day from baseline) or the late statin group (received pitavastatin 4 mg/day from 3 weeks after the baseline)...

The average survival for patients with Pancreatic Ductal Adenocarcinoma (PDA) is merely 6 months, underscoring the need for new therapeutic approaches. During PDA progression, pancreatic acinar cells lose activity of the ClassI/II bHLH factors that regulate quiescence. We previously found that promoting transcriptional activity of the Class I bHLH factor E47 in highly aggressive PDA cells induced stable growth arrest in vitro and in vivo. To translate these findings for clinical utility, we developed a high throughput screening platform to identify small molecule inducers of Class I/II bHLH activity...

BACKGROUND: There is a residual risk of coronary heart disease (CHD) despite intensive statin therapy for secondary prevention. The aim of this study was to investigate whether coronary plaque regression and stabilization are reinforced by the addition of eicosapentaenoic acid (EPA) to high-dose pitavastatin (PTV). METHODS: We enrolled 193 CHD patients who underwent percutaneous coronary intervention (PCI) in six hospitals. Patients were randomly allocated to the PTV group (PTV 4mg/day, n=96) or PTV/EPA group (PTV 4mg/day and EPA 1800mg/day, n=97), and prospectively followed for 6-8 months...

AIMS: We evaluated whether exercised-based cardiac rehabilitation (CR) can ameliorate the HDL function, i.e., cholesterol efflux capacity (CEC) and paraoxonase-1 activity in patients with acute coronary syndrome (ACS). METHODS: This study is a retrospective analysis of stored serum from patients with ACS following successful percutaneous coronary intervention. The CEC, measured by a cell-based ex vivo assay using apolipoprotein B-depleted serum and (3)H-cholesterol labeled macrophages and arylesterase activity (AREA) at the onset or early phase of ACS, and the follow-up periods were compared between 69 patients who completed the five-month outpatient CR program (CR group) and 15 patients who did not participate and/or dropped out from CR program (non-CR group)...

Only 40% of patients with advanced ovarian cancer survive more than 5 years. We have previously shown that pitavastatin induces regression of ovarian cancer xenografts in mice. To evaluate whether the response of ovarian cancer cells to pitavastatin is potentiated by farnesyl diphosphate synthase inhibitors or geranylgeraniol transferase I inhibitors, we evaluated combinations of pitavastatin with zoledronic acid, risedronate and GGTI-2133 in a panel of ovarian cancer cells. Pitavastatin (IC50 = 0.6-14 μM), zoledronic acid (IC50 = 21-57 μM), risedronate (IC50 > 100 μM) or GGTI-2133 (IC50 > 25 μM) inhibited the growth of ovarian cancer cell cultures...

Statins have pleiotropic effects that are considered beneficial in preventing cerebral vasospasm and delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage (aSAH). Many studies using statins have been performed but failed to show remarkable effects. We hypothesized that a long-acting statin would be more effective, due to a longer half-life and stronger pleiotropic effects. Patients with aSAH were randomly assigned to a pitavastatin group (4 mg daily; n = 54) and a placebo group ( n = 54) after repair of a ruptured aneurysm...

Purpose: The pleiotropic effects of statins (antioxidant and anti-inflammation) have been reported by previous studies. Therefore, we aimed to determine whether pitavastatin has protective effects against pentylenetetrazol (PTZ)-induced kindling in mice and also whether pitavastatin improves the brain antioxidant capacity and attenuates the oxidative injuries in kindled mice. Methods: Twenty-four mice were randomly divided into four groups (each group n=6); control, PTZ-kindling and PTZ-kindled rats treated with pitavastatin (1&4 mg/kg)...

Statins are competitive inhibitors of 3-hydroxy-3-methylglutaryl-CoA (HMG-A) reductase, and studies have shown that statins also have anti-inflammatory and immunomodulatory properties. The purpose of this study was to investigate the anti-asthmatic effects of pitavastatin, a type of statin, in an asthma mouse model. Mice were sensitized and challenged with ovalbumin (OVA) to establish the asthma model. These mice were then treated with inhaled pitavastatin (5 mg/kg) or dexamethasone (2 mg/kg), the latter of which served as a positive control...

REVIEW
Angela Pirillo, Alberico L Catapano
Low high density lipoprotein cholesterol (HDL-C) levels represent an independent risk factor for cardiovascular disease; in addition to the reduced HDL-C levels commonly observed in patients at cardiovascular risk, the presence of dysfunctional HDL, i.e. HDL with reduced atheroprotective properties, has been reported. Despite the established inverse correlation between HDL-C levels and cardiovascular risk, several clinical trials with HDL-C-increasing drugs (such as niacin, CETP inhibitors or fibrate) failed to demonstrate that a significant rise in HDL-C levels translate into a cardiovascular benefit...
