lncRNA NONRATT021972 siRNA Decreases Diabetic Neuropathic Pain Mediated by the P2X 3 Receptor in Dorsal Root Ganglia
Abstract Long noncoding RNAs (lncRNAs) participate in physiological and pathophysiological processes. Type 2 diabetes mellitus (T2DM) accounts for more than 90 % of all cases of diabetes mellitus (DM). Diabetic neuropathic pain (DNP) is a common complication of T2DM. The aim of this study was to investigate the effects of lncRNA NONRATT021972 small interference RNA (siRNA) on DNP mediated by the P2X3 receptor in dorsal root ganglia (DRG). These experiments showed that the expression levels of NONRATT021972 in DRG were increased in the T2DM rat model (intraperitoneal injection of STZ with 30 mg/kg). The concentra...

Treatment of the metabolic syndrome by siRNA targeting apolipoprotein CIII
AbstractApolipoprotein CIII (apoCIII) is increased in obesity-induced insulin resistance and type-2 diabetes. Emerging evidences support the advantages of small interfering RNAs (siRNAs) to target disease-causing genes. The aim of this study was to develop siRNAs for in vivo silencing of apoCIII and investigate if this results in metabolic improvements comparable to what we have seen using antisense oligonucelotides against apoCIII. Twenty-four siRNAs were synthesized and tested in a dual luciferase reporter assay. The eight best were selected, based on knockdown at 20  nM, and of these, two were selected based on IC50 v...

Resveratrol Promotes Diabetic Wound Healing via SIRT1-FOXO1-c-Myc Signaling Pathway-Mediated Angiogenesis
Conclusion: Our findings indicate that the positive role of RES in diabetic wound healing via its SIRT1-dependent endothelial protection and pro-angiogenic effects involves the inhibition of FOXO1 and the de-repression of c-Myc expression. Introduction Diabetes mellitus is a metabolic disease with an increasing incidence worldwide (Zimmet et al., 2014). The disease often leads to the development of serious complications such as microangiopathy, mainly including retinopathy, nephropathy, neuropathy, and diabetic non-healing skin ulcers (Zheng et al., 2018). Diabetic non-healing skin ulcers such as foot ulcers are ca...

Tangshen Formula Alleviates Hepatic Steatosis by Inducing Autophagy Through the AMPK/SIRT1 Pathway
Conclusion In conclusion, the present study demonstrated that autophagy was involved in relieving the effects of TSF against NAFLD, which were mediated by the AMPK/SIRT1 pathway (Figure 7D). These findings may improve our current understanding of the role of TSF in treating hepatic steatosis and provide an experimental basis for the clinical application of TSF in NAFLD and its related metabolic syndrome. Ethics Statement This study was carried out in accordance with the recommendations in the Guide for the Care and Use of Laboratory Animals of the National Institutes of Health. The protocol was approved by the Ethics Co...

p38α Mitogen-Activated Kinase Mediates Cardiomyocyte Apoptosis Induced by Palmitate.
CONCLUSIONS: These results demonstrate that PA induces p38α activation, and reducing p38α expression attenuates PA-induced cardiomyocyte apoptosis. Our results support a potential mechanism by which high plasma SFA levels through p38α activation may lead to the development of lipotoxic/diabetic cardiomyopathy.

lncRNA uc.48+ regulates immune and inflammatory reactions mediated by the P2X7 receptor in type 2 diabetic mice.
In conclusion, these data suggest that uc.48+ may play an important role in the pathological changes of blood pressure, neurology and abdominal cell function in T2DM via interaction with the P2X7 receptor. PMID: 33224283 [PubMed]

Suppression of Rho-kinase 1 is responsible for insulin regulation of the AMPK/SREBP-1c pathway in skeletal muscle cells exposed to palmitate
ConclusionsOur study indicated that insulin reduced lipotoxicity via ROCK1 and then improved AMPK/SREBP-1c signaling in skeletal muscle under PA-induced insulin resistance.

Ampelopsin Improves Insulin Resistance by Activating PPARγ and Subsequently Up-Regulating FGF21-AMPK Signaling Pathway
by Yong Zhou, Ying Wu, Yu Qin, Lei Liu, Jing Wan, Lingyun Zou, Qianyong Zhang, Jundong Zhu, Mantian Mi Ampelopsin (APL), a major bioactive constituent of Ampelopsis grossedentata, exerts a number of biological effects. Here, we explored the anti-diabetic activity of APL and elucidate the underlying mechanism of this action. In palmitate-induced insulin resistance of L6 myotubes, APL treatment markedly up- regulated phosphorylated insulin receptor substrate-1 and protein kinase B, along with a corresponding increase of glucose uptake capacity. APL treatment also increased expressions of fibroblast growth factor (FGF21) and...

LNK deficiency aggregates palmitate-induced preadipocyte apoptosis.
Abstract LNK (SH2B3) is an intracellular adaptor protein that negatively regulates cellular proliferation or self-renewal of hematopoietic stem cells and some other progenitor cells. LNK is also recognized as a key regulator of insulin resistance and inflammatory responses in several tissues and organs. It is unknown the function of LNK in adipose tissue. We previously demonstrated that type 2 diabetes mellitus (T2DM) mouse model had elevated serum free fatty acids (FFAs) levels and increased preadipocyte apoptosis in visceral fat tissue, showing the occurrence of lipotoxicity. Here we show that, in contrast with ...

LncRNA uc.48+ is involved in the diabetic immune and inflammatory responses mediated by P2X7 receptor in RAW264.7 macrophages.
Abstract High glucose combined with high FFAs can contribute to the unfavorable development of type 2 diabetes mellitus (T2DM) and monocytes/macrophages are important in the occurrence and development of T2DM, which is regarded as a type of low‑grade inflammation. Although our previous study demonstrated that increased expression of P2X7 receptor (P2X7R) in peripheral blood monocytes may alter the innate immune system and that long non‑coding (lnc)RNA uc.48+ was involved in diabetic neuropathic pain, the involvement of uc.48+ mediated by the P2X7R in monocyte/macrophages during T2DM has not been reported. In t...

A Novel Regulator of Preadipocyte Differentiation, Transcription Factor TCF21, Functions Partially Through Promoting LPL Expression
Discussion Excessive fat deposition in chickens can result in many undesirable consequences within the poultry industry, including reduced feeding efficiency (Zhou et al., 2006) and decreased reproductive performance (Walzem and Chen, 2014). Thus, broiler breeders urgently require a more thorough understanding of the molecular mechanism governing chicken adipogenesis. We previously found that broilers from lean and fat lines exhibit clear differences in reproductive performance (Zhang et al., 2018). In addition, TCF21 was found to be related to testis growth and development in these broilers (Zhang et al., 2017). In mice ...

H19 inhibition increases HDAC6 and regulates IRS1 levels and insulin signaling in the skeletal muscle during diabetes
CONCLUSIONS: Our results suggest a critical role for the lncRNA H19-HDAC6 axis in regulating IRS1 levels in the skeletal muscle during diabetes and therefore restoring normal H19 levels might hold a therapeutic potential for the management of aberrant skeletal muscle physiology during insulin resistance and type 2 diabetes.PMID:35842608 | DOI:10.1186/s10020-022-00507-3
