Introduction

Phosphorylation-dependent transcription factor that stimulates transcription upon binding to the DNA cAMP response element (CRE), a sequence present in many viral and cellular promoters. Transcription activation is enhanced by the TORC coactivators which act independently of Ser-119 phosphorylation. Involved in different cellular processes including the synchronization of circadian rhythmicity and the differentiation of adipose cells.

ETHNOPHARMACOLOGICAL RELEVANCEType 2 diabetes mellitus (T2DM) has become a public health problem worldwide. There is growing interest in finding drugs to treat T2DM from herbal medicine. Berberidis Cortex is a traditional Tibetan herb commonly used in the treatment of T2DM, and alkaloids are its main active components. However, the anti-diabetic mechanisms of the total alkaloids of Berberidis Cortex (TBC) remain unclear.AIM OF THE STUDYThe aim of this study was to evaluate the anti-T2DM efficacy of TBC and reveal the mechanisms behind its effects.MATERIALS AND METHODSUPLC-Q-Exactive Orbitrap MS technology was employed to qualitatively identify alkaloid components in TBC. T2DM rat models were induced by high-fat diet combined with streptozotocin, and then treated with different doses of TBC (43.5, 87, 174 mg/kg/d) for 40 days. Biochemical parameters, such as fasting blood glucose (FBG), oral glucose tolerance test (OGTT), glycated serum protein (GSP), homeostatic model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C), alongside H&E and PAS staining were used to evaluate the anti-diabetic activity of TBC. More importantly, metagenomics, transcriptomics, targeted metabolomics, and Western blot analysis were integrated to reveal the underlying mechanisms of TBC for T2DM treatment.RESULTSTBC significantly reduced the levels of FBG, OGTT, GSP, HOMA-IR, TC, TG, and LDL-C, and improved the histopathological alterations of pancreatic and liver tissues in T2D rats. It also reduced serum levels of lipopolysaccharide (LPS) and several pro-inflammatory cytokines (IL-6, IL-1β and TNF-α). Gut microbiome analysis by metagenomics proved that TBC could improve gut microbiota dysbiosis, including an increase in some beneficial bacteria (e.g., Bifidobacterium pseudolongum and Lactobacillus acidophilus) and a decrease in some harmful bacteria (e.g., Marvinbryantia and Parabacteroides). Western blot analysis found that TBC significantly up-regulated the expression of three intestinal barrier related tight junction proteins (ZO-1, occludin, and claudin-1), and effectively suppressed several key proteins in the TLR4/MyD88/NF-κB inflammatory cascade, including TLR4, MyD88 and p-NF-κB p65. Moreover, hepatic transcriptomics analysis further revealed the regulatory role of TBC on gluconeogenesis related genes, such as Pgc, and Creb1. Targeted metabolomics and Western blot analysis showed that TBC improved BAs dysregulation in T2DM rats, specifically increasing TCDCA and CA levels, thereby activating several proteins in the FXR/FGF15 signaling axis (i.e., FXR, FGF15 and FGFR4), and then decreased the expression of p-CREB1 and PGC-1α to inhibit liver gluconeogenesis.CONCLUSIONSTBC can significantly improve hyperglycemia, insulin resistance, hyperlipidemia, and inflammation in T2DM rats. The mechanism is related to the regulation of multiple links, including improving gut microbiota dysbiosis, protecting the intestinal barrier by up-regulating the expression of three tight junction proteins, reducing inflammation by inhibiting the LPS/TLR4/MyD88/NF-κB pathway, and inhibiting liver gluconeogenesis by regulating BAs/FXR/FGF15 and CREB1/PGC-1α signaling pathways.

The purpose of this study is to evaluate the influence of phospholipid-polymer nanoparticles (PNPs) on mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) signaling of dopaminergic neurons in degenerated brain. Resveratrol (RES)- and ceftriaxone (CEF)-entrapped PNPs with surface leptin (Lep) and transferrin (Tf) were fabricated to rescue both 1-methyl-4-phenylpyridinium (MPP⁺)-insulted SH-SY5Y cells and Wistar rats. Based on PNPs, anti-apoptosis of RES and CEF, and targeting of Lep and Tf were investigated. Experimental results revealed that 20-30 % alginic acid (Alg) yielded the maximal particle size, physical stability and entrapment efficiency of CEF, and the minimal release percentage of CEF. Increasing Alg content in PNPs decreased the entrapment efficiency of RES, and facilitated the release of RES. Optimized PNP composition was about 40 % Alg, 15 % phosphatidylserine and 45 % poly-ε-caprolactone. Lep-Tf-PNPs ameliorated brain permeability of RES and CEF without jeopardizing the blood-brain barrier, and promoted the viability of MPP⁺-insulted SH-SY5Y cells. Immunofluorescence images and western blots of MPP⁺-insulted SH-SY5Y cells showed that Lep-Tf-RES-CEF-PNPs upregulated dopamine transporter, tyrosine hydroxylase, B-cell lymphoma 2 (Bcl-2), cyclic AMP response element-binding protein and ERK5 expressions, and downregulated Bcl-2-associated X protein (Bax), α-synuclein (α-syn), phosphorylated tau protein (p-tau), c-Jun N-terminal kinase and ERK1/2 expressions. Lep-Tf-RES-CEF-PNPs unveiled a strong capacity to recover Bcl-2, Bax, α-syn and p-tau levels from MPP⁺ injury in the substantia nigra of rats. Hence, Lep-Tf-RES-CEF-PNPs can retard α-syn fibril formation, prevent tau protein from phosphorylation, and moderate MAPK/ERK and phosphatidylinositol 3-kinase/protein kinase B, and are promising for brain- and neuron-targeted pharmacotherapy to manage Parkinson's disease.

BACKGROUNDDysregulated circular RNAs (circRNAs) are involved in osteoarthritis (OA) progression.OBJECTIVEWe aimed to explore the effect of hsa_circ_0044719 (circTRIM25) on the ferroptosis of chondrocytes.METHODSChondrocytes were treated with interleukin (IL)-1β to generate cell model. Cellular behaviours were measured using cell counting kit-8, enzyme-linked immunosorbent assay, relevant kits, propidium iodide staining, and immunofluorescence assay. Quantitative real-time polymerase chain reaction was performed to examine the expression of circTRIM25, miR-138-5p, and cAMP responsive element binding protein 1 (CREB1), and their interactions were assessed using luciferase reporter analysis and RNA pull-down assay.RESULTSCircTRIM25 was upregulated in OA tissues and IL-1β-stimulated chondrocytes. Knockdown of circTRIM25 facilitated the viability and suppressed ferroptosis and inflammation of IL-1β-induced cells. CircTRIM25 served as a sponge of miR-138-5p, which directly targets CREB1. Downregulation of miR-138-5p abrogated the effect induced by knockdown of circTRIM25. Furthermore, enforced CREB1 reversed the miR-138-5p induced effect. Moreover, knockdown of circTRIM25 attenuated cartilage injury in vivo.CONCLUSIONSilencing of circTRIM25 inhibited ferroptosis of chondrocytes via the miR-138-5p/CREB axis and thus attenuated OA progression.
