An OA rat model was developed with unilateral anterior cruciate ligament transection (ACLT). Interventions comprised of BAI treatment and intra-articular administration of miR-766-3p inhibitor. For evaluation, histopathological staining was conducted to investigate the pathological severity of knee cartilage injury. The levels of oxidative stress (OS) indicators including MDA, SOD, and GSH-Px, were quantified using colorimetric assays. Inflammatory factors (IFs; TNF-?, IL-1?, and IL-6) in knee joint lavage fluids were assessed using ELISA, while RT-PCR was employed to quantify miR-766-3p expression. TUNEL apoptosis staining was utilized to detect chondrocyte apoptosis, and western blotting examined autophagy-related markers (LC3, Beclin, p62), extracellular matrix (ECM) synthesis-associated indices (COL2A, ACAN, MMP13), and apoptosis-inducing factor mitochondrion-associated 1 (AIFM1). Histological examination revealed a marked amelioration of cartilage injury in the BAI-treated OA rat models compared to controls. BAI treatment significantly reduced inflammation and OS of knee joint fluid, activated autophagy, and decreased chondrocyte apoptosis and ECM degradation. Interestingly, the inhibitory effects of BAI on these pathological markers were significantly decreased by the miR-766-3p inhibitor. Further assessment revealed that BAI efficiently promoted miR-766-3p expression while inhibiting AIFM1 protein expression. BAI potentially mitigates articular cartilage injury in OA rats, likely through modulation of miR-766-3p/AIFM1 axis.

Weight bearing, especially during growth, may be important to achieve normal acetabulum development. This study aimed to investigate whether hip bone morphologies were affected by hindlimb suspension (HS) in 4 week-old rats. In HS groups, tail suspension was applied for 0, 2, 4, and 8 weeks. Age-matched rats were used as controls. The complex of hip bones with lumbar and sacral vertebrae were assessed based on morphological indexes using three-dimensional reconstructed images from X-ray computed tomography. Acetabular widths (measured from cranial to caudal) unchanged and depths became larger in both groups with age. Acetabular lengths (from the ventral side to the dorsal side) became larger in control groups but unchanged in HS groups with age. In HS groups, acetabular width, length, and depths were smaller than the control groups at 4 and/or 8 weeks. Acetabular versions became enlarged (rotated inwards) with age in both groups, although this was particularly pronounced in HS groups. Histologically, triradiate cartilage layers in the acetabulum were thinner with age and almost disappeared at 8 weeks in both groups. However, HS decreased Safranin O staining and prolonged the presence of hypertrophic chondrocyte indicating alterations in the chondral ossification processes. Iliac wing angles remained unchanged and anterior superior iliac crest (ASIC) distances increased with age in controls. In contrast, HS groups showed narrowed iliac wing angles with small ASIC distances. These results suggest that reduced mechanical loading during growth can interfere with hip joint formation.

Eight-month-old female Sprague-Dawley rats were divided into four groups: 1) LLE: 18-month LLE training starting at 8 months of age, 2) Old moderate-intensity continuous training (OMICT): 8 months of moderate-intensity continuous training starting at 18 months of age, 3) Adult sedentary (ASED): 8 month-old adult sedentary control group, and 4) Old sedentary (OSED): a 26-month-old sedentary control group. Hematoxylin eosin staining was performed to observe the pathological changes of kidney tissue injury in rats; Masson's staining to observe the deposition of collagen fibers in rat kidney tissues; and western blotting to detect the expression levels of IL-6, IL 1beta, p53, p21, TNF-alpha, GPX4, KAEP 1, NRF2, SLC7A11, and other proteins in kidney tissues. Results: Compared with the ASED group, the OSED group showed significant morphological changes in renal tubules and glomeruli, which were swollen and deformed, with a small number of inflammatory cells infiltrated in the tubules. Compared with the OSED group, the expression levels of inflammation-related proteins such as IL-1beta, IL-6, TNF alpha, and MMP3 were significantly lower in the LLE group. Quantitative immunofluorescence analysis and western blotting revealed that compared with the ASED group, KAEP 1 protein fluorescence intensity and protein expression levels were significantly enhanced, while Klotho and NRF2 protein fluorescence intensity and protein expression levels were reduced in the OSED group. Compared with the OSED group, KAEP 1 protein fluorescence intensity and protein expression levels were reduced in the LLE and OMICT groups. Klotho and KAEP 1 protein expression levels and immunofluorescence intensity were higher in the LLE group than in the OSED group. The expression levels of GPX4 and SLC7A11, two negative marker proteins associated with ferroptosis, were significantly higher in the LLE group than in the OSED group, while the expression of p53 a cellular senescence-associated protein that negatively regulates SLC7A11, and the downstream protein p21 were significantly decreased. LLE may ameliorated aging-induced oxidative stress, inflammatory response, apoptosis, and ferroptosis by regulating Klotho and synergistically activating the NRF2/KAEP 1 pathway.

In the present study, we explored protein abundance and parameters related to oxidative stress in heart homogenates of rats exposed to chronic mild HHcy. Using two-dimensional gel electrophoresis followed by MALDI-TOF/TOF mass spectrometry 22 altered proteins (6 upregulated and 14 downregulated) were identified. For eight proteins the altered abundances were validated by Western blot analysis. Identified proteins are primarily involved in energy metabolism (mainly enzymes of glycolysis, pyruvate dehydrogenase complex, citric acid cycle, and ATP synthase), cardiac muscle contraction (alpha-actin and myosin light chains), stress response (heat-shock protein beta1 and alphaB-crystallin) and antioxidant defense (glutathione peroxidase 1). Diminished antioxidant defense was confirmed by decreases in total antioxidant capacity and GSH/GSSG ratio. Consistent with the decline in enzymatic and non-enzymatic antioxidant defense the protein oxidative modification, as determined by tyrosine nitration, was significantly increased.

Emerging evidence indicated that long non-coding RNA-regulator of reprogramming (linc-ROR) can promote epithelial-mesenchymal transition (EMT) in a variety of cancer cells. Nevertheless, the function of linc-ROR in EPC EndMT has not been well elucidated. The present study investigated the effect and possible mechanisms of function of linc-ROR on the EndMT of EPCs. A linc-ROR overexpression lentiviral vector (LV linc-ROR) or a linc-ROR short hairpin RNA lentiviral vector (LV-shlinc-ROR) was used to up or downregulate linc-ROR expression in EPCs isolated from human umbilical cord blood. Functional experiments demonstrated that LV-linc-ROR promoted the proliferation and migration of EPCs, but inhibited EPC angiogenesis in vitro. In the meantime, reverse transcription-quantitative PCR and western blotting results showed that the expression of the endothelial cell markers vascular endothelial-cadherin and CD31 was decreased, while the expression of the mesenchymal cell markers ?-smooth muscle actin and SM22? was increased at both mRNA and protein levels in LV-linc-ROR-treated EPCs, indicating that linc-ROR induced EPC EndMT. Mechanistically, the dual-luciferase reporter assay demonstrated that microRNA (miR/miRNA)-145 was a direct target of linc-ROR, and miR-145 binds to the 3'-untranslated region of Smad3. Moreover, LV-shlinc-ROR increased the expression of miR-145, but decreased the expression of Smad3. In conclusion, linc-ROR promotes EPC EndMT, which may be associated with the miR-145/Smad3 signaling pathway.

There are currently rare researches on the effect of vitamin supplementation on GDM pregnant mother and their offspring on animal and cell levels systematically. This work supplemented the GDM pregnant mouse model with vitamin D and found that vitamin D can effectively alleviate the hyperglycemia in GDM pregnant mice, increase blood insulin and adiponectin concentrations, and improve GTT and ITT in pregnant mice. In addition, vitamin D can reduce the incidence of death and high birth weight of offspring caused by GDM. The offspring of GDM pregnant mice had higher blood glucose levels in the first 5 weeks after birth compared to the normal group, and then returned to normal levels. Vitamin D can alleviate abnormal glucose metabolism in newborn mice. The therapeutic effect exhibited by vitamin D may be due to their anti-inflammatory effects, as vitamin D supplementation significantly reduces the levels of TFN-?, MCP-1, IL-1? and IL-8 in the blood. Vitamin D also regulates liver lipid metabolism, resulting in a decrease in liver lipid accumulation and a decrease in blood triglycerides (TG) and cholesterol (CHO).
