Obese diabetic rats have lowered ABCA1 expression, cholesterol efflux block, and cholesterol accumulation in the pancreatic tissue. MS-275 nmr Exenatide can up-regulate ABCA1 expression and promote cholesterol efflux to reduce cholesterol content in the pancreatic tissue and improve islet function in obese diabetic rats.

To analyze the species, abundance and structure differences of intestinal flora between patients with type 2 diabetes mellitus (T2D) and healthy individuals and explore the correlation between intestinal flora changes and T2D.

We collected a total of 133 clinical fecal samples from 78 healthy individuals and 55 patients with T2D. Hiseq2500 was used for high-throughput sequencing of the V3+V4 regions of the 16S rRNA gene. Usearch and QIIME were used for data splicing and filtering, classification and species annotation. The Alpha diversity index and Beta diversity index of the samples were analyzed using R language data packets to compare the richness and diversity of the sample flora. The flora differences were compared between the two groups and the disease marker flora was screened after correction of the relevant factors. PICRUST software was used to predict the function of different flora.

There was significant difference in the intestinal flora diversity between the two groups. Cluster analysis shombalance.
To establish animal models epidermal growth factor receptor inhibitor-related skin rashes using cetuximab, gefitinib or erlotinib.

Female SCID mice were randomly divided into blank control group and high-, moderate-, and low-dose cetuximab groups. The mice in control group received intraperitoneal injection of saline, and those in the 3 cetuximab groups were injected with 80, 40, and 20 mg/kg cetuximab (3 times a week for 4 weeks), respectively. The general skin appearance and skin pathologies of the mice were observed. Female BN rats were randomly divided into blank group, ovalbumin group, gefitinib group and erlotinib group, and in the latter 3 groups, the rats were given ovalbumin (1 mg), gefitinib (37.5 mg/kg), and erlotinib (23.5 mg/kg) by lavage once daily for 45 days, respectively. Skin pathologies of the rats were observed, and serum levels of TNF-
, IL-6 and other inflammatory factors were detected using ELISA.

Intraperitoneal injection of cetuximab did not induce typical skin rashes, scabs or skin rashes in SCID mice. Lavage of gefitinib, but not erlotinib, can be used to establish models of epidermal growth factor receptor inhibitor-related rashes in BN rats.
To investigate the mechanism by which amentoflavone inhibits polarization of THP-1-derived foam cells to M1 phenotype.

Human monocyte cell line THP-1 was stimulated to differentiate into M1-type macrophages using phorbol 12-myrislate13-acetate (PMA) combined with lipopolysaccharide (LPS) and recombinant human interferon-γ (rhlFN-γ). M1 polarization of THP-1-derived macrophages was confirmed by observing morphological changes of the cells and detecting the mRNA expression of L-6 and TNF-
with RT-qPCR. THP-1-derived foam cells treated with 5 or 10 μmol/L amentoflavone for 24 h were examined for cytokines using ELISA. The mRNA and protein expressions of IL-6, IL-10, TNF-
, TGF-β, PPAR-
/
, Arg-1 and Fizz1 in the cells were detected using RT-qPCR and Western blotting.

Amentoflavone prevented induced M1 polarization of THP-1 cells. Amentoflavone down-regulated the mRNA expressions of IL-6 and TNF-
, up-regulated mRNA expressions of IL-8 and TGF-β mRNA (
< 0.05), and increased the protein expressions of PPAR-
/
, Arg-1 and Fizz1. Molecular docking simulation showed that amentoflavone could bind to the surface of PPAR

.

Amentoflavone can inhibit the differentiation of macrophages into M1 type by activating PPAR-

and restoring the expressions of the gene Arg-1 and Fizz1.

To explore the effect of estradiol (E2) binding to its receptor ERβ on the proliferation and apoptosis of C28I2 cells.

We cloned the sequence of ESR2 into a recombinant adenovirus plasmid (pAd-ESR2) and packaged the plasmid in HEK293 cells. Normal human chondrocyte C28I2 cells were transfected with Ad-ESR2 or small interfering RNA targeting ESR2-siRNA (ESR2-siRNA), and the effects of treatment with DMSO or E2 on the expression of the proteins associated with endoplasmic reticulum (ER) stress and cell apoptosis were determined using Western blotting. qRT-PCR was used to detect the expressions of proliferation-related marker genes, and an EdU kit and flow cytometry were used to assess cell proliferation and apoptosis. We also tested the effects of U0126 (an ERK pathway inhibitor) and E2, alone or in combination, on ER stress, apoptosis and the ERK signaling pathway in C28I2 cells infected with Ad-ESR2 using Western blotting.

Overexpression of Ad-ESR2 in C28I2 cells significantly promoted the expressions of IRE1
, PERK, XBP1s, and cleaved caspase-12, inhibited proliferation related marker genes PCNA, cyclin B1, cyclin D1, and decreased the level of ERK phosphorylation following E2 treatment (all
< 0.05). Interference of ESR2 caused significant reduction in the expressions of ER stress-related proteins and apoptosis-related proteins, up-regulated the genes related to cell proliferation, and increased intracellular pERK/ERK ratio in C28I2 cells. The effect of E2 binding to ERβ, which promoted the expressions of ER stress associated proteins and apoptosis related proteins, was obviously antagonized by treatment of the cells with U0126.

The binding of E2 to ERβ promotes ER stress and apoptosis in human chondrocytes by activating ERK pathway phosphorylation inhibit cell proliferation.
