Abstract
Several studies including ours reported the detrimental effects of extracellular tau oligomers (ex-oTau) on glutamatergic synaptic transmission and plasticity. Astrocytes greatly internalize ex-oTau whose intracellular accumulation alters neuro/gliotransmitter handling thereby negatively affecting synaptic function. Both amyloid precursor protein (APP) and heparan sulfate proteoglycans (HSPGs) are required for oTau internalization in astrocytes but the molecular mechanisms underlying this phenomenon have not been clearly identified yet. Here we found that a specific antibody anti-glypican 4 (GPC4), a receptor belonging to the HSPG family, significantly reduced oTau uploading from astrocytes and prevented oTau-induced alterations of Ca2+-dependent gliotransmitter release. As such, anti-GPC4 spared neurons co-cultured with astrocytes from the astrocyte-mediated synaptotoxic action of ex-oTau, thus preserving synaptic vesicular release, synaptic protein expression and hippocampal LTP at CA3-CA1 synapses. Of note, the expression of GPC4 depended on APP and, in particular, on its C-terminal domain, AICD, that we found to bind Gpc4 promoter. Accordingly, GPC4 expression was significantly reduced in mice in which either APP was knocked-out or it contained the non-phosphorylatable amino acid alanine replacing threonine 688, thus becoming unable to produce AICD. Collectively, our data indicate that GPC4 expression is APP/AICD-dependent, it mediates oTau accumulation in astrocytes and the resulting synaptotoxic effects.

Abstract
Constantly stimulated by the tumor microenvironment (TME), programmed death 1 (PD‑1) is elevated, and it interacts with PD ligand 1 (PD‑L1), rendering chimeric antigen receptor (CAR)‑T cells dysfunctional. Hence, CAR‑T cells immune to PD‑1‑induced immunosuppression were constructed to improve the function of CAR‑T cells in hepatocellular carcinoma (HCC). Double‑target CAR‑T cells, targeting glypican‑3 (GPC3) [a tumour-associated antigen (TAA)] and hindering PD‑1‑PD‑L1 binding, were established. The expression of GPC3, PD‑L1, and inhibitory receptors was measured using flow cytometry. The cytotoxicity, cytokine release, and differentiation level of CAR‑T cells were determined using lactate dehydrogenase release assay, enzyme‑linked immunosorbent assay, and flow cytometry, respectively. HCC cells were targeted and eliminated by double‑target CAR‑T cells. These double‑target CAR‑T cells limit PD‑1‑PD‑L1 binding and sustain cytotoxicity to PD‑L1+ HCC cells. The relatively low IR expression and differentiation level in double‑target CAR‑T cells in tumour tissues induced tumour‑suppression and extended survival in PD‑L1+ HCC TX models, as opposed to their single‑target counterparts. The results of the present study suggested that the newly constructed double‑target CAR‑T cells exhibit stronger tumour‑suppressing effects in HCC than their single‑target counterparts, which are common, suggesting the potential of strengthening CAR‑T cell activity in HCC treatment.

Abstract
Oxaliplatin (cyclohexane-1,2-diamine; oxalate; platinum [2+]) is a third-generation chemotherapeutic drug with anticancer effects. Oxaliplatin has a role in the treatment of several cancers. It is one of the few drugs which can eliminate the neoplastic cells of colorectal cancer. Also, it has an influential role in breast cancer, lung cancer, bladder cancer, prostate cancer, and gastric cancer. Although oxaliplatin has many beneficial effects in cancer treatment, resistance to this drug is in the way to cure neoplastic cells and reduce treatment efficacy. microRNAs are a subtype of small noncoding RNAs with ∼22 nucleotides that exist among species. They have diverse roles in physiological processes, including cellular proliferation and cell death. Moreover, miRNAs have essential roles in resistance to cancer treatment and can strengthen sensitivity to chemotherapeutic drugs and regimens. In colorectal cancer, the co-treatment of oxaliplatin with anti-miR-19a can partially reverse the oxaliplatin resistance through the upregulation of phosphatase and tensin homolog (PTEN). Moreover, by preventing the spread of gastric cancer cells and downregulating glypican-3 (GPC3), MiR-4510 may modify immunosuppressive signals in the tumor microenvironment. Treatment with oxaliplatin may develop into a specialized therapeutic drug for patients with miR-4510 inhibition and glypican-3-expressing gastric cancer. Eventually, miR-122 upregulation or Wnt/β-catenin signaling suppression boosted the death of HCC cells and made them more sensitive to oxaliplatin. Herein, we have reviewed the role of microRNAs in regulating cancer cells' response to oxaliplatin, with particular attention to gastrointestinal cancers. We also discussed the role of these noncoding RNAs in the pathophysiology of oxaliplatin-induced neuropathic pain.

Abstract
Obesity, especially visceral obesity, is associated with insulin resistance and metabolic syndrome. We previously identified the cell surface proteoglycan glypican-4 as differentially expressed in subcutaneous versus visceral white fat depots. Here we show that glypican-4 is released from cells and adipose tissue explants of mice, and that circulating glypican-4 levels correlate with BMI and insulin sensitivity in humans. Furthermore, glypican-4 interacts with the insulin receptor, enhances insulin receptor signaling, and enhances adipocyte differentiation. Conversely, depletion of glypican-4 results in reduced activation of the insulin receptor and prevents adipocyte differentiation in vitro by inhibiting insulin-mediated C/EBPβ phosphorylation. These functions of glypican-4 are independent of its glycosylphosphatidylinositol membrane anchorage, as a nonmembrane-bound mutant of glypican-4 phenocopies the effects of native glypican-4 overexpression. In summary, glypican-4 is a novel circulating insulin sensitizing adipose-derived factor that, unlike other insulin sensitizers, acts directly on the insulin receptor to enhance signaling.

Abstract
OBJECTIVE To construct glypican-3 (GPC3)-green fluorescent protein eukaryotic expression vector pEGFP-c3-GPC3, and analyze the effect of GPC3 on the proliferation of human hepatoma cell line MHCC-97L. METHODS The eukaryotic expression vector pEGFP-c3-GPC3 was constructed with recombinant DNA technique and transfected into MHCC-97L cells via Lipofectamine 2000. The cells stably expressing GPC3 were screened by flow cytometry and G418. The mRNA expression of GPC3 was detected by RT-QPCR method, and the protein expression by Western blotting and fluorescence microscope. The effect of GPC3 gene on the growth of the cells was examined by MTT assay. RESULTS Restriction endonuclease analysis and DNA sequencing verified correct construction of the recombinant plasmid. The green fluorescence was detected in the transfected MHCC-97L cells under fluorescence microscope. RT-QPCR and Western blotting both confirmed successful expression of GPC3 in MHCC-97L cells. The growth curve showed a significant acceleration of the proliferation of the transfected MHCC97-Lsol;GPC3 cells as compared with MHCC97-L and MHCC97-L/C3 cells (P<0.001). CONCLUSION We have successfully constructed the eukaryotic expression vector pEGFR-c3-GPC3, which allows stable GPC3 expression in MHCC97-L/GPC3 cells. The upregulation of GPC3 expression can stimulate the growth of hepatoma cell line MHCC97-L in vitro.

Abstract
Simpson-Golabi-Behmel syndrome (SGBS) is an X-linked condition shown to be the result of deletions of the glypican-3 (GPC3) gene. GPC3 is a proteoglycan localized to the cell membrane via a glycosylphosphatidyl-inositol (GPI) anchor. To further elucidate the GPC3 function(s), we have screened various cell lines for proteins that interact with GPC3, resulting in the isolation of a 115 kDa protein, identified as CD26. The interaction occurred with both the glycosylated and unglycosylated forms of GPC3 and led to the inhibition of CD26 peptidase activity. Moreover, introduction of CD26 into Cos-1 cells was accompanied by the up-regulation of cell growth, while inclusion of recombinant GPC3 in the media reduced the growth of CD26 transfected Cos-1 cells, drastically. Furthermore, HepG2 C3A cells containing CD26 underwent apoptosis in the presence of recombinant GPC3 in both concentration and time-dependant manner. In light of the fact that inhibition of CD26 reduces the rate of cell proliferation, we propose that a number of physical findings observed in SGBS patients may be a consequence of a direct interaction of GPC3 with CD26. Furthermore, GPC3 without the GPI anchor is capable of inducing apoptosis indicating that neither the GPI anchor nor the membrane attachment is required for apoptosis induction.
