Abstract Macrophages are polarized into functional classically activated and alternatively (M2) phenotypes depending on their microenvironment, these cells play an important role in the immune system. M2-like polarization of tumor-associated macrophages (TAMs) is by various secretions from cancer cells; however, interaction between TAMs not well understood. Recent studies showed that cell–derived extracellular vesicles (EVs) contribute to tumor development modulation microenvironment. In...

The metabolism in tumor cells shifts from oxidative phosphorylation to glycolysis even an aerobic environment. This phenomenon is known as the Warburg effect. effect regulated mainly by polypyrimidine tract‐binding protein 1 ( PTBP ), which a splicer of m RNA for rate‐limiting enzymes glycolysis, pyruvate kinase muscle and 2 PKM 2). In present study, we demonstrated that miR‐133b reduced expression at translational level levels were significantly downregulated gastric cancer clinical samples...

Serine and arginine rich splicing factor 3 (SRSF3), an SR-rich family protein, has oncogenic function in various kinds of cancer. However, the detailed mechanism had not been previously clarified. Here, we showed that SRSF3 splicer regulated expression profile pyruvate kinase, which is one rate-limiting enzymes glycolysis. Most cancer cells express kinase muscle 2 (PKM2) dominantly to maintain a glycolysis-dominant energy metabolism. Overexpression SRSF3, as well another splicer,...

The Warburg effect is a well-known feature in cancer-specific metabolism. We previously reported on the role of microRNA (miR)-145 as tumor-suppressor human bladder cancer (BC) cells. In this study, we reveal that miR-145 decreases by silencing KLF4 BC expression levels were significantly lower clinical samples and cell lines compared to those normal tissues HUC Luciferase assay results showed directly bound 3'UTR KLF4, which was shown be overexpressed using Western blot analysis...

Epigenetic modifications control cancer development and clonal evolution in various types. Here, we show that loss of the male-specific histone demethylase lysine-specific 5D (KDM5D) encoded on Y chromosome epigenetically modifies methylation marks alters gene expression, resulting aggressive prostate cancer. Fluorescent situ hybridization demonstrated segmental or total deletion cells is one causes decreased KDM5D mRNA expression. The result ChIP-sequencing analysis revealed preferably...

Abstract Background Currently, only limited knowledge is available regarding the phenotypic association between fibroblast growth factor receptor 3 (FGFR3) alterations and tumor microenvironment (TME) in bladder cancer (BLCA). Methods A multi-omics analysis on 389 BLCA 35 adjacent normal tissues from a cohort of OMPU-NCC Consortium Japan was retrospectively performed by integrating whole-exome RNA-sequence dataset clinicopathological record. median follow-up duration all 31 months. Results...

We developed an automated enzymatic method for determination of the branched-chain amino acids (BCAAs; valine, isoleucine, leucine) and tyrosine in serum, applied it to clinical evaluation patients with various hepatic diseases. Analytically, test results were acceptably precise reproducible, correlated well obtained acid analyzer. Clinically, we found that a decrease BCAAs, increase tyrosine, BCAAs/tyrosine ratio serum paralleled severity parenchymal damage. conclude this BCAAs is simple...

Abstract The Warburg effect is a well-known feature of cancer cells. However, its' functional significance hasn't been elucidated yet. Pyruvate kinase muscle (PKM), which rate-limiting glycolytic enzyme, has 2 isoforms, PKM1 and PKM2. It reported that PKM2 tumor-specific isoform promotes the effect. Also, it thought tumor cells switch their PKM from to during development. Here, we showed this switching machinery was induced only in limited cases, based on expression normal tissues...

Recently, several systemic inflammation-based scores, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte (PLR), lymphocyte-to-monocyte (LMR), modified Glasgow prognostic score (GPS), and nutritional index (PNI), have been proposed factors for cancers. In this study, we aimed to determine the influence of scores nutrition status on outcome in patients receiving chemotherapy unresectable pancreatic cancer.A total 93 consecutive who underwent cancer at Osaka Medical College...

Evidence for the occurrence of bound serotonin was not demonstrated by various physicochemical procedures using rabbit blood platelets. Thus, when separated completely from platelet proteins, ultrafiltrate a homogenate contained same concentration as unfiltered and, at equilibrium after dialysis homogenate, outside bag practically equal to that on inside. The absorption platelets stimulated glucose and this stimulation inhibited inhibitors oxidation an uncoupler oxidative phosphorylation....

MicroRNAs (miRNAs) are small RNAs present in extracellular vesicles (EVs) that, when transferred to a target cell, affect its biological functions. Plant miRNAs regulate the expression of certain mammalian genes. Here, we characterized EVs fruit and vegetable juice, their miRNA cargo, investigated whether such miRNA-containing could be taken up by enterocytes vitro. Using filtration ultra-centrifugation methods, were purified from commercially available manually squeezed plant juice. EV...
