In this paper, we investigated the anticancer effect and the mechanism of our newly synthesized bibenzyl 8Ae against human lung cancer A549 cells. Compound 8Ae could induce apoptosis by inhibiting the glycolysis in A549 cells. Hexokinase 2 (HK2), the first key enzyme in glycolysis process, was significantly down-regulated by 8Ae.

Dual-specificity tyrosine phosphorylation-regulated kinase A (DYRK1A) is a potential drug target for diabetes. The DYRK1A inhibitor can promote β cells proliferation, increase insulin secretion and reduce blood sugar in diabetes. In this paper, a series β-carboline-cinnamic acid skeletal derivatives were designed, synthesized and evaluated to inhibit the activity of DYRK1A and promote pancreatic islet β cell proliferation.

Thioredoxin interacting protein (TXNIP) is a potential drug target for type 2 diabetes mellitus (T2DM) treatment. A series of quinazoline derivatives were designed, synthesised, and evaluated to inhibit TXNIP expression and protect from palmitate (PA)-induced β cell injury. In vitro cell viability assay showed that compounds D-2 and C-1 could effectively protect β cell from PA-induced apoptosis, and subsequent results showed that these two compounds decreased TXNIP expression by accelerating its protein degradation.

The catalytic conversion of CO or CO/CO mixtures to higher alcohols (HAs) using hydrogenation reactions remains challenging in C1 chemistry and also one of the most promising reactions for the utilization of non-petroleum resources. Here, the experiment and characterization tests of CuCoMn/AlO show that copper is much more dispersed on γ-AlO than cobalt, and the interaction between cobalt and Mn metals is stronger. And, mixed cobalt-manganese oxides are formed in the calcined catalyst, promoting the formation of higher alcohols.

This study aims to explore the role of Ang II in diet-induced obesity by focusing on adipose lipid anabolism and catabolism.

Methods: Rat model of AT1aR gene knockout were established to investigate the special role of Ang II on adipose lipid metabolism.

Introduction: There are few investigations describing the pregnancy-associated listeriosis in China, and the molecular characteristics of causing such infections remain largely unknown. We aim to investigate the phenotypic and genomic profiles of pregnancy-associated isolates and their association with isolates recovered from human and non-human in China.

Materials And Methods: In this study, we conducted a 3-year surveillance of listeriosis in a women's hospital in Zhejiang province, using whole genome sequencing and bioinformatics tools.

Background: As an emerging research area of artificial enzymes, nanozyme, the catalytic nanomaterials with enzyme-like characteristics, have attracted enormous attention in research. Here, a nanozyme probe has been realized by utilizing antigen-labeled mesoporous silica-encapsulated Au-core Pt-shell (Au@Pt@SiO) nanostructures for the diagnosis of rubella virus (RV). Pt nanoparticles have been suggested to act as potent peroxidase mimetics with high activities.

Acute myeloid leukemia (AML) is a devastating hematological malignancy, characterized by differentiation arrest and unscheduled proliferation of immature cells of the myeloid lineage. Inducing AML cell differentiation has emerged as a promising therapeutic strategy for the therapy of AML. Icariside II, an active component of Herba Epimedii, has been well defined to promote osteogenic differentiation.

Background: Mitochondrial pyruvate import via mitochondrial pyruvate carrier (MPC) is a central step in hepatic gluconeogenesis. Berberine inhibits hepatic gluconeogenesis, but the mechanism is incompletely understood. This study aims to investigate whether berberine could reduce excessive hepatic glucose production (HGP) by limiting mitochondrial import of pyruvate through MPC1.

Hepatitis E is believed to occur in both endemic and sporadic forms in developing countries, which causes a major public health problem in Asia and Africa (Meng, 2010; Wang et al., 2016a). Recent studies have documented that the disease is also endemic in many industrialized countries (Wenzel et al.

Background: This study was designed to investigate whether ginsenoside Rb1 (Rb1) and compound K (CK) ameliorated insulin resistance by suppressing endoplasmic reticulum (ER) stress-induced inflammation in adipose tissue.

Methods: To induce ER stress, epididymal adipose tissue from mice or differentiated 3T3 adipocytes were exposed to high glucose. The effects of Rb1 and CK on reactive oxygen species production, ER stress, TXNIP/NLRP3 inflammasome activation, inflammation, insulin signaling activation, and glucose uptake were detected by western blot, emzyme-linked immunosorbent assay, or fluorometry.

To investigate the changes of physiological and biochemical indexes, male mice were fed a regular diet or short time high fat diet (HFD) for 10 days with oral administration of saline, metformin, resveratrol, or injected intraperitoneally (ip) with digoxin respectively every day. Food intake and body weight were recorded simultaneously. Blood was collected after mice were sacrificed and then tested with commercial kits.

This study aims to investigate the effects of metformin and resveratrol on muscle insulin resistance with emphasis on the regulation of lipolysis in hypoxic adipose tissue. ICR mice were fed with high fat diet (HFD) for 10days with administration of metformin, resveratrol, or intraperitoneal injection of digoxin. Adipose hypoxia, inflammation and cAMP/PKA-dependent lipolysis were investigated.

Objective: This study was designed to investigate the hypothesis that metformin and resveratrol exhibited the same effect on inhibition of NLRP3 inflammasome activation with regulation of AMPK in adipose tissue exposed to high glucose.

Methods: To induce adipose tissue dysfunction, we treated epididymal adipose tissue of mice or differentiated 3T3-L1 adipocytes with high glucose (33 mM) for 24 h. Meanwhile, mice were injected with streptozotocin STZ to induce diabetes and followed by oral administration of metformin (200 mg/kg), resveratrol (50 mg/kg) or ER stress inhibitor TUDCA (50 mg/kg) for 7 days.

Background And Purpose: Hypoxic activation of hypoxia-inducible factor 1α (HIF-1α) and fibrosis in adipose tissue contribute to adipose dysfunction. This study was designed to investigate the effects of metformin and resveratrol on the regulation of HIF-1α and fibrosis in hypoxic adipose tissue.

Experimental Approach: Mice were fed a high-fat diet to induce hypoxia and fibrosis in adipose tissue; adipose tissue incubated in vitro in 1% O2 showed a similar change.

Embryonic mortality during the implantation period strongly affects litter size in pigs. To analyze the differentially expressed genes (DEGs) in the endometrium during implantation and further to identify candidate genes for litter size, tissues of endometrial attachment sites and intersites were collected from nine pregnant sows on Days 13, 18, and 24 of pregnancy. Endometrium tissue was also collected from another three nonpregnant sows.

α-Keto acid of pefloxacin mesylate (PFLX) can form the complex with Terbium(III). The intramolecular energy from PFLX to Terbium(III) ion takes place when excited, and thus Terbium(III) excited state is formed and then emits the characteristic fluorescence of Terbium(III), locating at 490, 545, 580, and 620 nm. The second-order scattering (SOS) peak at 545 nm also appears for the complex with the exciting wavelength of 273 nm.

Hepatitis E virus (HEV) genotypes 1 and 2 are restricted to humans, whereas genotypes 3 (HEV 3) and genotype 4 (HEV 4) infect humans and a variety of animal species. Cross-species infections by animal strains raise potential public health concerns for zoonotic HEV transmission. Therefore, a real-time reverse transcription polymerase chain reaction (RT-qPCR) combining the HEV 3-tpye specific RT-qPCR assay with the HEV 4-tpye specific assay was developed.

Neuropeptide Y (NPY) mediates stress-induced obesity in adult male mice by activating its Y2 receptor (Y2R) in visceral adipose tissue (VAT). Here, we studied whether the NPY-Y2R system is also activated by maternal low-protein diet (LPD) and linked to obesity in offspring. Prenatal LPD offspring had lower birth weights compared to normal-protein diet (NPD) offspring.
