Background: Testicular cancer survivors (TCS) are at significantly increased risk for cardiovascular disease (CVD), with metabolic syndrome (MetS) an established risk factor. No study has addressed clinical and genetic MetS risk factors in North American TCS. Patients and Methods: TCS were aged <55 years at diagnosis and received first-line chemotherapy. Patients underwent physical examination, and had lipid panels, testosterone, and soluble cell adhesion molecule-1 (sICAM-1) evaluated. A single nucleotide polymorphism in rs523349 (5-α-reductase gene, SRD5A2 ), recently implicated in MetS risk, was genotyped...

The number of people living with and beyond cancer is at an all time high. These survivors are not necessarily living well, as adverse side effects from cancer and its treatment can last up to 5 years and leave patients at a higher risk of developing secondary cancers and other chronic illnesses. Exercise has been proven to be a safe and effective method of intervention to decrease mortality and overall improve health outcomes. The biological mechanism through which this occurs is an area of research that is in its infancy and not well defined...

INTRODUCTION: High dietary saturated fat intake is associated with higher blood concentrations of low-density lipoprotein cholesterol (LDL-C), an established risk factor for coronary heart disease. However, there is increasing interest in whether various dietary oils or fats with different fatty acid profiles such as extra virgin coconut oil may have different metabolic effects but trials have reported inconsistent results. We aimed to compare changes in blood lipid profile, weight, fat distribution and metabolic markers after four weeks consumption of 50 g daily of one of three different dietary fats, extra virgin coconut oil, butter or extra virgin olive oil, in healthy men and women in the general population...

A phase 1 dose-escalation trial assessed the chemotherapeutic potential of ammonium perfluorooctanoate (APFO). Forty-nine primarily solid-tumor cancer patients who failed standard therapy received weekly APFO doses (50mg-1200mg) for six-weeks. Clinical chemistries and plasma PFOA (anionic APFO) were measured pre-dose and weekly thereafter. Several clinical measures including total cholesterol, high-density lipoproteins (HDL), thyroid stimulating hormone (TSH), and free thyroxine (fT4), relative to PFOA concentrations, were examined by: standard statistical analyses using general estimating equations (GEE) and a probabilistic analysis using probability distribution functions (pdf) at various PFOA concentrations; and a two-compartment pharmacokinetic/pharmacodynamic (PK/PD) model to directly estimate mean changes...

BACKGROUND/PURPOSE: One to three per cent of the world's population has hepatitis C virus (HCV) infection, which is not only a major cause of liver disease and cancer but also associated with an increased risk of atherosclerosis, despite an ostensibly favourable lipid profile. Autoantibodies are frequent in HCV infection and emerging evidence shows that autoantibodies could be valuable for cardiovascular disease (CVD) risk stratification. This study investigated a novel independent biomarker of CVD, autoantibodies to apolipoprotein A-1 (anti-apoA-1 IgG) and lipids in patients with chronic HCV before, during and after direct-acting anti-viral (DAA) therapy...

ATP-binding cassette transporter A1 (ABCA1) has been found to mediate the transfer of cellular cholesterol across the plasma membrane to apolipoprotein A-I (apoA-I), and is essential for the synthesis of high-density lipoprotein. Mutations of the ABCA1 gene may induce Tangier disease and familial hypoalphalipoproteinemia; they may also lead to loss of cellular cholesterol homeostasis in prostate cancer, and increased intracellular cholesterol levels are frequently found in prostate cancer cells. Recent studies have demonstrated that ABCA1 may exert anticancer effects through cellular cholesterol efflux, which has been attracting increasing attention in association with prostate cancer...

BACKGROUND: Scavenger receptor class B type I (SR-BI) has been reported to be involved in carcinogenesis of several human cancers. However, it is currently unknown whether SR-BI plays a role in clear cell renal cell carcinoma (ccRCC). Here, we aimed to evaluate a tumor promotive mechanism for SR-BI in ccRCC. METHODS: The expression of SR-BI was evaluated by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR), Western blot and immunohistochemistry (IHC) in ccRCC tissues and cell lines...

Medulloblastoma is the most common paediatric malignant brain cancer and there is a need for new targeted therapeutic approaches to more effectively treat these malignant tumours, which can be divided into four molecular subtypes. Here, we focus on targeting sonic hedgehog (SHH) subtype medulloblastoma, which accounts for approximately 25% of all cases. The SHH subtype relies upon cholesterol signalling for tumour growth and maintenance of tumour-initiating cancer stem cells (CSCs). To target cholesterol signalling, we employed biomimetic high-density lipoprotein nanoparticles (HDL NPs) which bind to the HDL receptor, scavenger receptor type B-1 (SCARB1), depriving cells of natural HDL and their cholesterol cargo...

Breast cancer is amongst the most common cancers causing death of women worldwide. Breast cancer occurrence is more prominent in people with diabetes. A recent trend is management of diabetes and cancer has evolved to be natural remedy including single molecule therapy or combination. In this study, we investigated the effect of inotodiol on breast cancer growth in diabetic conditions. Inotodiol is a lanostane triterpenoid found in natural resources like edible mushroom Inonotus obliquus. We established a rat model of diabetic-breast cancer by treating female Sprague-Dawley rats with streptazotocin (STZ) at 35 mg/kg followed by induction of breast cancer by administration of 7,12-dimethylbenz(a)anthracene (DMBA) at 10 mg/kg...

BACKGROUND: Subclinical hypothyroidism is associated with dyslipidemia and atherosclerosis. Whether part of these effects are mediated via direct effects of TSH on peripheral TH metabolism and/or concentrations of serum lipids is not clear. OBJECTIVE: To examine whether thyroid stimulating hormone (TSH) has direct effects on peripheral thyroid hormone (TH) metabolism and serum lipids. METHODS: We retrospectively analyzed 82 patients with differentiated thyroid cancer...

Allium hookeri has been widely cultivated and used as a vegetable and medicine in Asia, but its anti-obesity effects have not been previously reported. In this study, the effects of a leaf extract of A. hookeri on obesity were investigated by administering a high-fat diet (HFD) to mice. Male Institute of Cancer Research mice (n = 32; 5 weeks old) were randomly divided into four groups: normal-diet group, HFD group, HFD containing 200 mg/kg/day A. hookeri leaf extract (HFD-A1), and HFD containing 400 mg/kg/day A...

Cardiovascular morbidity is closely associated with serum lipid level. We aimed to investigate the effects of different aromatase inhibitors, including letrozole, anastrozole, and exemestane, on the lipid profile of eastern Chinese breast cancer patients. We evaluated a retrospective cohort of eastern Chinese postmenopausal women with early-stage breast cancer who received aromatase inhibitors. A total of 116 postmenopausal women with early-stage breast cancer without prior cardiovascular disease were included...

BACKGROUND: Epidemiologic evidence for a serum cholesterol-prostate cancer link is mixed. Prostate-specific antigen (PSA) is positively correlated with cholesterol, potentially increasing PSA-driven biopsy recommendations in men with high cholesterol, though biopsy compliance may be lower in men with comorbid conditions. These potential biases may affect PSA-driven biopsy rates and subsequent prostate cancer detection in men with high serum cholesterol. Our objective was to test the association between serum cholesterol and prostate cancer risk in men receiving PSA independent, study-mandated prostate biopsies...

BACKGROUND: The alterations of lipid profile in cancer has been reported to be associated with cancer development. However, the prognostic value of serum lipid markers level in cancer is currently under debate. Here we performed a meta-analysis to investigate the prognostic significance of serum blood total cholesterol (TC), Triglycerides (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) for cancer. METHODS: We systematically searched in PubMed and EMBASE for follow-up studies to evaluate the association between blood TC, TG, HDL-C, LDL-C and overall survival (OS) or disease-free survival (DFS) in patients with cancer...

BACKGROUND: Arterial stiffness is known to be associated with a number of clinical conditions including hypertension, diabetes and dyslipidemia, and may predict cardiovascular events and mortality. However, causal links are hard to establish. Results from genome-wide association studies have identified only a few single nucleotide polymorphisms associated with arterial stiffness, the results have been inconsistent between studies and overlap with other clinical conditions is lacking. Our aim was to investigate a potential shared set of risk single nucleotide polymorphisms between relevant cardiometabolic traits and arterial stiffness...

Background: Metabolic syndrome is associated with cardiovascular diseases and is characterized by insulin resistance. Recent studies suggest that the triglyceride/high-density lipoprotein cholesterol (TG/HDLC) ratio predicts insulin resistance better than individual lipid levels, including TG, total cholesterol, low-density lipoprotein cholesterol (LDLC), or HDLC. We aimed to elucidate the relationship between the TG/HDLC ratio and metabolic syndrome in the general Korean population. Methods: We evaluated the data of adults ≥20 years old who were enrolled in the Korean National Health and Nutrition Examination Survey in 2013 and 2014...
