Abstract Background This study aimed to investigate the diagnostic function of CD36 in type 2 diabetic (T2DM) sepsis complications (T2DSC) and its effect on β-cell differentiation. Methods First, Age - and sex-matched T2DM patients, T2DSC patients and healthy people (50 cases each) were included. Quantitative polymerase chain reaction was used to measure CD36, FOXO1, PDX1, MAFA, insulin, SOX9, Neurog3 and NANOG expression in blood samples. Second, cultured human β-cell line EndoC-βH1 and the interference and overexpression of CD36. Cell clone, apoptosis, inflammatory cytokine, oxidative stress and β-cell differentiation related proteins were also analysed. Third, examined the role of CD36 in high glucose, LPS-induced β-cell. Results CD36 mRNA, and endocrine progenitor β-cell biomarkers SOX9, Neurog3 and NANOG were significantly increased in T2DM than control group, whereas the β-cell maturation biomarkers FOXO1, PDX1, MAFA and insulin were significantly decreased. Compared with the T2DM group, CD36 and FOXO1 were significantly increased in T2DSC, but PDX1, insulin, MAFA, SOX9, Neurog3 and NANOG were significantly decreased. The receiver operating characteristic curve revealed that CD36 was useful for distinguishing T2MD and T2DSC from the control group. Furthermore, CD36 overexpression increased β-cell apoptosis and the secretion of IL-1β, IL-8 TNF-α, malondialdehyde and reactive oxygen species. CD36 induced cell defferentiation. Lastly, CD36 knockdown could inhibit the high glucose and LPS-induced cell apoptosis, inflammatory, oxidative stress and cell defferentiation. Conclusion Significant increase in CD36 can be used as a biomarker for T2MD and T2DSC. CD36 promotes T2MD or T2DSC development by inducing β-cell inflammatory and oxidative stress and defferentiation.

Abstract Increasing evidence has indicated a close relationship between diabetes mellitus (DM) and disc degeneration. As a potential therapeutic growth factor, osteogenic protein-1 (OP-1) has lots of protective effects on the healthy disc cell’s biology. The present study was aimed to investigate the effects of OP-1 on degenerative changes of nucleus pulposus (NP) cells in a high glucose culture. Rat NP cells were cultured in the baseline medium or the high glucose (0.2 M) culture medium. OP-1 was added into the high glucose culture medium to investigate whether its has some protective effects against degenerative changes of NP cells in the high glucose culture. NP cell apoptosis ratio, caspase-3/9 activity, expression of apoptosis-related molecules (Bcl-2, Bax, and caspase-3), matrix macromolecules (aggrecan and collagen II), and matrix remodeling enzymes (MMP-3, MMP-13, and ADAMTS-4), and immuno-staining of NP matrix proteins (aggrecan and collagen II) were evaluated. Compared with the baseline culture, high glucose culture significantly increased NP cell apoptosis ratio, caspase-3/9 activity, up-regulated expression of Bax, caspase-3, MMP-3, MMP-13 and ADAMTS-4, down-regulated expression of Bcl-2, aggrecan and collagen II, and decreased staining intensity of aggrecan and collagen II. However, the results of these parameters were partly reversed by the addition of OP-1 in the high glucose culture. OP-1 can alleviate high glucose microenvironment-induced degenerative changes of NP cells. The present study provides that OP-1 may be promising in retarding disc degeneration in DM patients.

AbstractMaternal hyperglycemia potentially inhibits the development of the fetal heart by suppressing cardiomyocyte proliferation and promoting apoptosis. Different studies have indicated that miRNAs are key regulators of cardiomyocyte proliferation, differentiation, and apoptosis and play a protective role in a variety of cardiovascular diseases. However, the biological function of miRNA-23a in hyperglycemia-related cardiomyocyte injury is not fully understood. The present study investigated the effect of miRNA-23a-3p on cell proliferation and apoptosis in a myocardial injury model induced by high glucose. H9c2 cardiomyocytes were exposed to high glucose to establish an in vitro myocardial injury model and then transfected with miRNA-23a-3p mimics. After miRNA-23a-3p transfection, lens-free microscopy was used to dynamically monitor cell numbers and confluence and calculate the cell cycle duration. CCK-8 and EdU incorporation assays were performed to detect cell proliferation. Flow cytometry was used to measured cell apoptosis. Upregulation of miRNA-23a-3p significantly alleviated high glucose-induced cell apoptosis and cell proliferation inhibition (p < 0.01 and p < 0.0001, respectively). The cell cycle of the miRNA-23a-3p mimics group was significantly shorter than that of the negative control group (p < 0.01). The expression of cell cycle–activating and apoptosis inhibition-associated factors Ccna2, Ccne1, and Bcl-2 was downregulated by high glucose and upregulated by miRNA-23a-3p overexpression in high glucose-injured H9c2 cells. miRNA-23a-3p mimics transfection before high glucose treatment had a significantly greater benefit than transfection after high glucose treatment (p < 0.0001), and the rescue effect of miRNA-23a-3p increased as the concentration increased. This study suggests that miRNA-23a-3p exerted a dose- and time-dependent protective effect on high glucose-induced H9c2 cardiomyocyte injury.
