Metabolism of neoplastic cells is shifted toward high glucose uptake and enhanced lactate production. Lactate dehydrogenase (LDH), which is comprised of two major subunits, LDH-A and LDH-B, reversibly catalyzes the conversion of pyruvate to lactate or lactate to pyruvate. LDH-A has a higher affinity for pyruvate and is a key enzyme in the glycolytic pathway. Elevated LDH is a negative prognostic biomarker not only because it is a key enzyme involved in cancer metabolism, but also because it allows neoplastic cells to suppress and evade the immune system by altering the tumor microenvironment...

BACKGROUND: Remethylation of homocysteine is catalyzed by B12 dependent methionine synthase (MTR) in all types of cells and by B12 non-dependent betaine homocysteine methyltransferase (BHMT) in liver and kidney cells. Of many etiologies of cancer, an unexplored area is the variations of genes implicated in methylation reaction. OBJECTIVE: The study evaluated the association of BHMT (rs3733890) with acute lymphoblastic leukemia (ALL), followed by in-silico characterization of variations in BHMT gene...

BACKGROUND: Cancer progression has been associated with altered immune cell function and activation. Neopterin, which is secreted by interferon-γ stimulated macrophages, exhibits an association with multiple cancer types and metastatic disease. Chitotriosidase, which is secreted by chronically activated macrophages and granulocyte-macrophage colony-stimulating factor stimulated neutrophils has not been studied in the setting of cancer. OBJECTIVE: The goal of this discovery study was to screen chitotriosidase for diagnostic capacity in detecting cancer and compare its operating characteristics with those of neopterin...

However, the antiapoptotic mechanism of PPAR-α is still unknown. Fenofibrate is a PPAR-α agonist In the present study, we investigate the effects and relevant mechanism of fenofibrate on experimental myocardial ischemia-reperfusion (I/R) injury in rats.

OBJECTIVE: The transcription factor FOXF2 is reported to be down-regulated in HCC. Its deficiency is correlated with shorter disease-free survival and overall survival of HCC patients; however, the mechanism remains to be elucidated. MATERIALS AND METHODS: In this study, we performed qRT-PCR and western blotting to confirm the down-regulated FOXF2 in HCC tissue and cell lines. Then the HCC cell line Huh7 transduced with FOXF2 shRNA was adopted in a series of in vitro and in vivo assays to evaluate the cell phenotype change, migration, invasion, proliferation, colonization of circulating cell and the formation of metastatic nodules...

BACKGROUND: Members of the SIRT family are a highly conserved family of NAD+-dependent enzymes, many of which (SIRT1-7) play an important role in tumor formation. Recently, several studies have suggested that SIRT4 not only regulates glutamine metabolism, but also serves as a tumor suppressor. There are no studies have assessed its clinical significance in endometrioid adenocarcinoma. METHODS: We investigated SIRT4 protein levels in endometrioid adenocarcinoma and its possible association with selected clinico-pathological parameters by immunohistochemical staining of a tissue microarray that included 65 endometrioid adenocarcinoma patients...

BACKGROUND: Bcl-2 interacting mediator of cell death (Bim) appears to have contradictory roles in cancer. It is uncertain whether Bim show prognostic significance in patients with breast cancer. OBJECTIVE: To investigate the correlation between Bim expression and clinicopathological characteristics of breast cancer and to evaluate Bim's effect on overall survival (OS). METHODS: We used immunohistochemistry (IHC) technique to detect the expression of Bim via tissue microarray in 275 breast cancer samples, Kaplan-Meier analysis to perform survival analysis, and Cox proportional hazards regression model to explore the risk factors of breast cancer...

The SerpinE2 pathway is evolutionarily conserved and plays an important role in tumorigenesis. SerpinE2 (a small ubiquitin-related modifier), like ubiquitin, conjugates SerpinE2 proteins onto lysine residues of target proteins. SerpinE2 over-expression has been found in several tumors. Here, we detected the level of SerpinE2 in 72 samples of EC tissue using immunohistochemistry to assess the role of SerpinE2 in EC prognosis. Meanwhile, we knocked down SerpinE2 by siRNA in the HTB-111 and Ishikawa EC cell lines and analyzed the viability and mobility change using an MTT assay, an annexin V/PI apoptosis assay, a wound scratch test and a transwell assay...
