AIM: To investigate the potential inhibitory effect of pterostilbene on the endothelial-to-mesenchymal transition(EndMT)induced by high glucose conditions in human retinal microvascular endothelial cells(HRMECs).METHODS: The optimal concentration of pterostilbene for treating HRMECs was determined using the CCK-8 assay, with 12.5 and 25 μmol/L concentrations selected for subsequent experiments. Four experimental groups were established: control group, high glucose group, high glucose combined with 12.5 μmol/L pterostilbene treatment group, and high glucose combined with 25 μmol/L pterostilbene treatment group. The expression levels of HDAC7 and EndMT-associated markers were detected via Western blot analysis. Cell migration ability was assessed using Transwell migration assays and scratch wound healing tests, while vasculogenic capability was evaluated through tube formation assays.RESULTS: The CCK-8 assay revealed that pterostilbene at a concentration of 22.07 μmol/L inhibited 50% of cell viability in HRMECs. Western blot analysis demonstrated that compared with the control group, the expression levels of HDAC7, ZEB1, Vimentin, and Snail were significantly upregulated in HRMECs cultured in high glucose(all P<0.01), while the expressions of VE-cadherin and CD31 were significantly reduced(all P<0.01). Compared to the high glucose group, the treatment with 12.5 and 25 μmol/L pterostilbene significantly reduced the expression of HDAC7, ZEB1, Vimentin, and Snail under high glucose conditions(all P<0.01). Notably, 25 μmol/L pterostilbene enhanced the expression of VE-cadherin and CD31(all P<0.01). Scratch wound healing tests revealed that HRMECs treated with high glucose exhibited a significantly increased cell migration rate compared to the control group(P<0.05), while the application of 25 μmol/L pterostilbene significantly suppressed HRMECs migration under high glucose conditions(P<0.01). Transwell migration assays demonstrated that the cell migration rate in the high glucose group was significantly higher than that in the control group(P<0.01), with cell migration rate markedly reduced following treatment with both of 12.5 and 25 μmol/L pterostilbene(all P<0.01). The tube formation assay revealed that the ability of HRMECs to form tubular structures was significantly enhanced under high glucose conditions(P<0.01), and both 12.5 and 25 μmol/L of pterostilbene effectively inhibited this effect(all P<0.01).CONCLUSION: Pterostilbene can inhibit HDAC7 expression, suppress EndMT-mediated migration of HRMECs, and impair tube formation under high-glucose conditions.

Pyroptosis, an inflammatory caspase-dependent programmed cell death, plays a vital role in maintaining tissue homeostasis and activating inflammatory responses. Orthodontic tooth movement (OTM) is an aseptic force-induced inflammatory bone remodeling process mediated by the activation of periodontal ligament (PDL) progenitor cells. However, whether and how force induces PDL progenitor cell pyroptosis, thereby influencing OTM and alveolar bone remodeling remains unknown. In this study, we found that mechanical force induced the expression of pyroptosis-related markers in rat OTM and alveolar bone remodeling process. Blocking or enhancing pyroptosis level could suppress or promote OTM and alveolar bone remodeling respectively. Using Caspase-1-/- mice, we further demonstrated that the functional role of the force-induced pyroptosis in PDL progenitor cells depended on Caspase-1. Moreover, mechanical force could also induce pyroptosis in human ex-vivo force-treated PDL progenitor cells and in compressive force-loaded PDL progenitor cells in vitro, which influenced osteoclastogenesis. Mechanistically, transient receptor potential subfamily V member 4 signaling was involved in force-induced Caspase-1-dependent pyroptosis in PDL progenitor cells. Overall, this study suggested a novel mechanism contributing to the modulation of osteoclastogenesis and alveolar bone remodeling under mechanical stimuli, indicating a promising approach to accelerate OTM by targeting Caspase-1.

ObjectiveTo observe the effect of Shufeng Jiedu capsule (SFJD)-containing serum on human lung epithelial cells infected by influenza A virus, and investigate the protective effect of the drug on the cells and the potential antiviral effect. MethodThe SFJD-containing serum was prepared and used to treat human lung epithelial cells (BEAS-2B) cultured in vitro. The viability of cells treated with different concentrations of SFJD-containing serum was measured by the cell counting kit-8 (CCK-8), and the optimal concentration of SFJD-containing serum was screened for subsequent experiments. BEAS-2B cells were classified into normal control, virus infection, and SFJD-containing serum groups, and the CCK-8 method was used to detect the survival rate of BEAS-2B cells after virus infection and drug administration. The expression of influenza virus nucleic acid in the cells of each group was determined, and the apoptosis of cells in different groups was observed by fluorescence microscopy. Real-time PCR was employed to determine the mRNA levels of influenza virus nucleoprotein (NP), Toll-like receptor 4 (TLR4), and myeloid differentiation primary response gene 88 (MyD88) in each group of cells. The immunofluorescence assay was used to detect the fluorescence intensities of TLR4, MyD88, and phosphorylated nuclear factor-κB (p-NF-κB) in lung epithelial cells. ResultCompared with that in the control group (normal serum), the cell survival rates in the blank serum and the SFJD-containing serum (5%, 10%, and 20%) groups were 100.00%±0.00%, 89.05%±4.80%, 87.13%±5.90%, 93.83%±6.03%, and 99.33%±3.39%, respectively (P<0.01). The SFJD-containing serum of 20% was selected as the optimal treatment for subsequent experiments. Compared with the normal control group, the virus infection group showed reduced cell survival rate (P<0.01), and the reduction was increased by the SFJD-containing serum (P<0.01). Compared with the virus infection group, SFJD-containing serum reduced the virus load (P<0.01) to decrease apoptosis. Compared with the normal control group, the virus infection group showed up-regulated mRNA levels of NP, TLR4, and MyD88 (P<0.01), and the up-regulation was down-regulated by the SFJD-containing serum (P<0.05, P<0.01). The fluorescence intensities of TLR4, MyD88, and p-NF-κB proteins in the cells increased after virus infection compared with those in the normal control (P<0.05, P<0.01), and they were decreased after administration with the SFJD-containing serum (P<0.05). ConclusionThe SFJD-containing serum can inhibit influenza virus in vitro by increasing the survival rate, reducing the apoptosis, and down-regulating the protein levels of TLR4, MyD88, and p-NF-κB in BEAS-2B cells.

OBJECTIVE To explore the impact and mechanism of curcumin on endometriosis (EMS) model rats based on Notch1 signaling pathway. METHODS Female SD rats with synchronized estrous cycles were implanted with autologous endometrium on the abdominal wall to construct EMS model. EMS rats were randomly divided into model group, low-, medium- and high-dose groups of curcumin (60, 120, 240 mg/kg), and Notch 1 inhibitor DAPT group (7 mg/kg). The sham surgery group was also established, with 10 rats in each group. Rats in each group received intragastric administration or injection via caudal veins with the corresponding drugs for 4 weeks. Endometriotic lesions were observed and measured using ultrasound and visual inspection, and their volumes were calculated. Histopathological morphology of the lesion tissues was observed. The levels of interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α) in the abdominal cavity fluid, as well as the mRNA and protein expression levels of Notch1, matrix metalloproteinase-9 (MMP-9), and vascular endothelial growth factor (VEGF) in the endometriotic lesions were measured. RESULTS Compared with the model group, the volume of endometriotic lesions in the low- , medium- and high-dose groups of curcumin and the DAPT group was significantly decreased (P<0.05); atrophy or disappearance of columnar epithelium, cyst disappearance; the levels of IL-1β, IL-6, and TNF- α (except for the low-dose curcumin group) in the abdominal cavity fluid, as well as the mRNA (except for MMP-9 and VEGF in the low-dose curcumin group) and protein (except for MMP-9 in the low-dose curcumin group) expression levels of Notch1, MMP-9, and VEGF in the endometriotic lesions were significantly decreased (P<0.05). The curcumin high-dose group and DAPT group showed superior results in most indicators compared to the curcumin low- and medium-dose groups. CONCLUSIONS Curcumin has an improving effect on EMS, and its mechanism may be related to inhibiting Notch1 signaling pathway, reducting local inflammatory responses, and inhibiting ectopic endometrial invasion and angiogenesis.
