OBJECTIVE
Fatigue is the most common and distressing symptom reported by cancer patients during and after treatment. Tumor growth increases oxidative stress and cytokine production, which causes skeletal muscle wasting and cardiac dysfunction. The purpose of this study was to determine whether
The mitochondrial electron transport chain (ETC) is necessary for tumour growth1-6 and its inhibition has demonstrated anti-tumour efficacy in combination with targeted therapies7-9. Furthermore, human brain and lung tumours display robust glucose oxidation by
High consumption of dietary fat promotes colon carcinogenesis. While this effect is well known the underlying mechanism is not understood. Fatty acid hydroperoxides (LOOH) arise from unsaturated fatty acids in the presence of oxygen and elevated temperature during food processing. An approach was
We previously reported the identification of a novel zinc-finger gene, designated ZSG, fused to Ewing sarcoma gene (EWS) by a submicroscopic paracentric inversion of 22q12 in a small round cell sarcoma presenting a translocation t(1;22)(p34;q12). We report here the molecular cloning and
Recently, we identified a novel therapeutic target and a small molecule for regulating angiogenesis. Our study showed that ubiquinol-cytochrome c reductase binding protein (UQCRB) of the mitochondrial complex III plays a crucial role in hypoxia-induced angiogenesis via mitochondrial reactive oxygen
Isoflavonoids have been shown to inhibit tumor proliferation and metastasis by activating cell death pathways. As such, they have been widely studied as potential therapies for cancer prevention. The second generation synthetic isoflavan analogues ME-143 and ME-344 also exhibit anti-cancer effects,
Introduction: Cancer-related fatigue (CRF) is the most debilitating symptom with the greatest adverse side effect on quality of life. The etiology of this symptom is still not understood. The purpose of this study was to examine the relationship between mitochondrial gene expression,
Patients with non-seminoma testicular cancer (NSTC) cancer can be subfertile or infertile, and present reduced sperm quality, but the underlying mechanisms are unknown. The aim of this study was to compare the sperm proteome of patients with NSTC, who cryopreserved their sperm before Ubiquinol-cytochrome C reductase core protein II (QCR2) is essential for mitochondrial functions, yet, its role in cancer development has remained elusive.The expression of QCR2 in cancer patients was assessed by immunohistochemistry. The proliferation of BACKGROUND
There is evidence that both carnitine and coenzyme Q 10 (Co Q), which are important for the functioning of myocardial mitochondria, are deficient in patients with congestive heart failure, in association with increased pro-inflammatory cytokines. It is possible that supplementation with
We investigated the role of mitochondrial function in the invasiveness of human colorectal cancer (CRC) cell lines, using paired primary SW480 and metastatic SW620 cells, and appraised the clinical relevance of the alteration of mtDNA copy number in 33 pairs of CRC specimens after surgical
Ubiquinol (QH), a reduced form of coenzyme Q10, is a lipid antioxidant that is hydro-soluble and is commonly formulated in commercial supplements. Ubiquinol has been increasingly reported to exert antioxidant functions, in addition to its role in the cell energy-producing system of mitochondria and
Generation of toxic oxygen metabolites followed by oxidant- and inflammatory-mediated tissue injury plays a crucial role in the pathogenesis of ischemia and reperfusion (IR). Ubiquinol, the reduced form of coenzyme Q10, is recognized for its potent antioxidant and anti-inflammatory properties in
Withaferin A (WA), a steroidal lactone derived from a medicinal plant (Withania somnifera), inhibits cancer development in transgenic and chemically-induced rodent models of breast cancer but the underlying mechanism is not fully grasped. We have shown previously that WA treatment causes apoptotic
Purpose: Pancreatic ductal adenocarcinoma (PDAC) is a malignant disease with a poor prognosis. One prominent aspect of PDAC that contributes to its aggressive behavior is its altered cellular metabolism. The aim of this study was to characterize the oncogenic effects of ubiquinol-cytochrome c
