Predictive pharmacogenetic biomarkers for breast cancer recurrence prevention by simvastatin.

Conclusion: Our study provides weak evidence to support the use of genetic variation in ABCB1, SLCO1B1, CYP3A4, and CYP3A5 as biomarkers of breast tumor response to simvastatin. Validation of these findings within adjuvant clinical trials is encouraged. PMID: 32351149 [PubMed - as supplied by publisher]

Abstract Obesity is associated with hypercholesterolemia and is a global epidemic. Epidemiological and animal studies revealed cholesterol is an essential regulator of estrogen receptor positive (ER+) breast cancer progression while inhibition of cholesterol accumulation was found to prevent breast tumor growth. Individually, vitamin D and LXR agonist T0901317 showed anticancer properties. The present study investigated the effects of vitamin D3 (VD3, calcitriol), LXR agonist (T0901317) and a combination of VD3 + T0901317 on cholesterol metabolism and cancer progression in ER+ breast cancer (MCF-7) c...

In conclusion, it remains unclear if brain-specific regional and temporal changes occur in the expression of the different APP variants during AD progression. Since APP is also found in blood cells, assessing the changes in APP mRNA expression in peripheral blood cells from AD patients has been considering an alternative. However, again the quantification of APP mRNA in peripheral blood cells has generated controversial results. Brain APP protein has been analyzed in only a few studies, probably as it is difficult to interpret the complex pattern of APP variants and fragments. We previously characterized the soluabl...

Blood tests can tell us a lot about what’s going on in our bodies—from whether we’re eating too much sugar to whether we’re harboring any infectious diseases. Scientists lately have been working on ways to use similar diagnostic tools for cancer, which have the potential to dramatically increase the amount of information doctors use to figure out the best treatments for their patients. Called liquid biopsies, these tests are designed to pick up genetic material shed by cancer tumors into the blood, which lets doctors avoid the invasive procedures needed to extract samples directly from tumors. That ...

The objective of this study was to assess the possible association of lipid profiles (total cholesterol TC, low-density lipoprotein LDL, very-low-density lipoprotein VLDL, high-density lipoprotein HDL, non-HDL and triglyceride TG), Chitinase-3-Like Protein1 (YKL-40) and changes in the levels of certain trace elements (Cu, Mg, Fe, and Zn), antioxidant status (TAC) and nitric oxide (NO) in benign and breast cancer in Egyptian females population. For 56 females with a benign breast tumor, 58 females with breast cancer, besides 52 healthy controls, Serum lipid profile, YKL-40, TAC, NO, Cu, Fe, Zn, and Mg have been determined. ...

Authors: Alarfi H, Youssef LA, Salamoon M Abstract Preclinical studies support the anticancer activity of statins; however, the existing clinical evidence is inconsistent and not definitive. Our study aimed at evaluating a postulated cancer chemo-sensitizing effect of statin (simvastatin) in a cohort of metastatic breast cancer (MBC) patients. We designed a prospective, single-centered, randomized, double blinded, placebo-controlled trial that encompassed MBC patients with an ECOG Performance Status Scale ≤2 and scheduled to be treated with a chemotherapy regimen consisting of carboplatin and vinorelbine every 3...

In this study, we sought to elucidate the role of VRK-1 in regulation of adult life span in C. elegans. We found that overexpression of VRK-1::GFP (green fluorescent protein), which was detected in the nuclei of cells in multiple somatic tissues, including the intestine, increased life span. Conversely, genetic inhibition of vrk-1 decreased life span. We further showed that vrk-1 was essential for the increased life span of mitochondrial respiratory mutants. We demonstrated that VRK-1 was responsible for increasing the level of active and phosphorylated form of AMPK, thus promoting longevity. A Fisetin Variant, C...

Chemotherapy has led to improved survival in patients with breast cancer; however, it is associated with an increased risk of cardiac dysfunction and heart failure. We investigated the protective effects of rosuvastatin and candesartan, alone and in combination, in a doxorubicin- and trastuzumab-induced rat model of cardiomyopathy.

AbstractPurposeInflammatory breast cancer (IBC) is a rare, poorly understood and aggressive tumor. We extended prior findings linking high body mass index (BMI) to substantial increased IBC risk by examining BMI associations before and after adjustment for well-characterized comorbidities using medical record data for diabetes, insulin resistance, and disturbances of cholesterol metabolism in a general community healthcare setting.MethodsWe identified 247 incident IBC cases diagnosed at Kaiser Permanente Northern California between 2005 and 2017 and 2470 controls matched 10:1 on birth year and geographic area and with &thi...
