Citrate is one of the major substrates for intracellular metabolism. The extracellular level of citrate is stable in blood but varies locally, with slightly increased levels in brain and high levels in prostate. Recent metabolomics research suggests that citrate level is a potential harbinger of different pathophysiological states; its decrease has been correlated with male infertility, brain diseases and metastatic cancer. In this review we Read More

Metastasis, the main cause of mortality in cancer patients, is a complex process consisting of several sequential, interlinked, and highly-selective steps. Fibroblast growth factor-inducible 14 (Fn14) is one member of the tumor necrosis factor receptor family, which is influential in controlling cell division, life, and death. The role of Fn14 in tumor metastasis regulation is slowly being unraveled, including roles in the regulation of the Read More

Atherosclerosis and its complications represent the leading death cause worldwide, despite many therapeutic developments. Atherosclerosis is a complex, multistage disease whereby perturbed lipid metabolism leads to cholesterol accumulation into the vascular walls and plaque formation. Generation of apoE-/- and LDLR-/- atherosclerosis mouse models opened the avenue for investigating the mechanisms of action for spec Read More

Ectonucleotide pyrophosphatase/phosphodiesterase 2 (ENPP2) also known as Autotaxin, is a secreted lysophospholipase D, which hydrolyzes lysophosphatidylcholine (LPC) into Lysophosphatidic acid (LPA). LPA is the bioactive product of ENPP2 enzyme, which induces diverse signalling pathways via six LPA-G-protein coupled receptors (GPCRs). ENPP2 is an essential protein for normal development and its altered express Read More

The protein serine/threonine phosphatases-1 and -2A are major cellular phosphatases, playing a fundamental role in organisms from prokaryotes to eukaryotes. They contribute to 90% dephosphorylation in eukaryote proteins. In the eye, both phosphatases are highly expressed and display important functions in regulating normal eye development. Moreover, they are implicated in pathogenesis through modulation of stress- Read More

Homeobox (HOX) transcript antisense RNA (HOTAIR), a long nuclear-retained noncoding RNA (lncRNA), is overexpressed in a variety of human cancers. Increasing evidence shows that HOTAIR plays a vital role in cancer initiation and progression by affecting cell cycle progress, apoptosis and invasion. However, whether HOTAIR serves as a target of therapeutic potential and the underlying mechanism in head and neck squam Read More

Burkholderia pseudomallei is the causative agent of melioidosis and represents a potential bioterrorism threat. In this study, the transcriptomic responses of B. pseudomallei infection of a human macrophage cell model were investigated using whole-genome microarrays. Gene expression profiles were compared between infected THP-1 human monocytic leukemia cells with or without treatment with Daboia russelli russelli Read More

Lipodystrophy is a common complication in HIV-infected patients taking highly active antiretroviral therapy. Its early diagnosis is crucial for timely modification of antiretroviral therapy. We hypothesize that mitochondrial DNA in plasma may be a potential marker of LD in HIV-infected individuals. In this study, we compared plasma mitochondrial DNA levels in HIV-infected individuals and non-HIV-infected individuals to investigate its Read More

Alzheimer’s disease (AD) is a neurodegenerative disorder which mainly affects elderly population. MicroRNAs (miRNA) are small RNA molecules that fine-tune gene expression at posttranscriptional level and exert important functions in AD. MicroRNA-124 (miR-124) is a kind of miRNA abundantly expressed in the central nervous system. It is highly conserved from Caenorhabditis elegans to humans. However, its function in AD is st Read More

Aberrant activation of Wnt/β-catenin signaling pathway is commonly associated to cancer development. However, molecular mechanisms controlling Wnt/β-catenin signaling pathway have been clarified only in part. Here, we show that β-catenin is differently modulated in patients with multiple sclerosis (MS), displaying that different pharmacological treatments used for clinical MS management cause different nuclear e Read More
