Roles and Mechanisms of Choline Metabolism in Nonalcoholic Fatty Liver Disease and Cancers.

Choline participates in three major metabolic pathways: oxidation, phosphorylation, and acetylation. Through oxidation, choline is converted to betaine and contributes to methyl metabolism and epigenetic regulation. Through phosphorylation, choline participates in phospholipid metabolism, and serves as the precursor of phosphocholine, phosphatidylcholine, glycerophosphocholine, and other essential compounds, thereby modulating lipid metabolism and transport.

EGFRvⅢ-targeted immunotoxin combined with temozolomide and bispecific antibody for the eradication of established glioblastoma.

EGFRvⅢ is an established target for immunotherapy of glioblastoma (GBM). Current study aims to explore the efficacy of EGFRvⅢ-targeted immunotoxin combined with temozolomide (TMZ) or T cell-engaged bispecific antibody for the treatment of GBM. We generated three rabbit monoclonal antibodies (R1, R2, and R6) that specifically bound to EGFRvⅢ, but not EGFR, with high affinity.

Strengthening of antitumor effects in breast cancer from a novel B7-H4- and CD3-targeting bispecific antibody by an oncolytic virus.

Background: For programmed cell death protein 1/programmed death-ligand 1 (PD-L1)-positive triple-negative breast cancer (TNBC), the addition of immune checkpoint inhibitors (ICIs) to chemotherapy has been shown to increase the objective response rate (ORR) by only 13.4-16.3%.

Degradation study of rutin as template from magnetic composite molecularly imprinted polymer supernatant samples by liquid chromatography-mass spectrometry.

Compound structure change of the template molecule from rutin samples might affect the selectivity and adsorption of molecularly imprinted polymers based on magnetic halloysite nanotubes (MHNTs@MIPs). In the present study, not only MHNTs@MIPs were successfully characterized by TEM, SEM, EDS, FT-IR, TGA and VSM, but related compounds and potential degradation factors of template molecule rutin were also investigated in the polymerization and elution process of MHNTs@MIPs by high-performance liquid chromatography together with photodiode array and tandem mass spectrometry (HPLC-PDA-MS/MS) in negative ion mode. Nine flavonol components were detected in rutin active pharmaceutical ingredient samples, such as rutin, isoquercetrin, kaempferol-3-O-rutoside, isorhamnetin-3-O-rutoside, quercetin, kaempferol, isorhamnetin and two unknown triglycosides.

Generation of TIM3 inhibitory single-domain antibodies to boost the antitumor activity of chimeric antigen receptor T cells.

Targeting inhibitory immune checkpoint molecules has significantly altered cancer treatment regimens. T cell immunoglobulin and mucin domain 3 (TIM3) is one of the major inhibitory immune checkpoints expressed on T cells. Blocking the engagement of TIM3 and its inhibitory ligand galectin-9 may potentiate the effects of immunotherapy or overcome the adaptive resistance to the therapeutic blockade of programmed cell death protein 1, cytotoxic T-lymphocyte-associated protein 4, B- and T-lymphocyte attenuator and lymphocyte-activation gene 3, amongst others, as each of these immune checkpoints harbors unique properties that set it apart from the rest.

Angptl7 promotes insulin resistance and type 2 diabetes mellitus by multiple mechanisms including SOCS3-mediated IRS1 degradation.

Angptl7 is a secreted and circulating cytokine that belongs to Angiopoietin-like family. The current knowledge about the function of Angptl7 is still limited, and its biological role is only marginally known, such as in the promotion of angiogenesis and inflammation. Here, we demonstrated that Angptl7 promotes insulin resistance and type 2 diabetes mellitus (T2DM).
