This study investigates the role of SPARC in hypertension, focusing on its impact on endothelial dysfunction.Using the GSE75815 dataset from the GEO database, we identified 71 differentially expressed genes (DEGs) associated with hypertension.

In this study, we investigated the anti-lung cancer activity of lotusine, a natural alkaloid, in the A549 (non-EGFR mutant), and EGFR-mutant HCC827 NSCLC cell line (deletion in exon 19). Our results demonstrated that lotusine significantly inhibited cell proliferation in a concentration- and time-dependent manner of HCC827 cells in comparison to A549 cells. Mechanistic analysis revealed that lotusine induced apoptosis in HCC827 cells, as evidenced by increased expression of pro-apoptotic markers (Bax and cleaved caspase-3) and decreased levels of anti-apoptotic proteins (Bcl-2). Cell cycle analysis indicated that lotusine caused G0/G1 phase arrest. Importantly, lotusine exerted its effects through the inhibition of the epidermal growth factor receptor (EGFR) EGFR-Akt-ERK signaling pathway, as evidenced by reduction of p-EGFR, p-Akt, and p-ERK in a western blot analysis in HCC827 cells. These findings suggest that lotusine exerts potent anti-cancer effects via a multifaceted mechanism, including inhibition of proliferation, apoptosis induction, and cell cycle arrest, predominantly mediated by EGFR suppression.

CCK-8 experiment and flow cytometry were used to detect cell proliferation and apoptosis in each group. ELISA is used to detect the levels of TNF-α, IL-8, and IL-6. Western blot was used to detect protein levels of Bax, Bcl-2, Cleaved Caspase-3, Aggrescan, Col II, MMP-1, MMP-13, BMP2, and p-Smad1/5 in each group. Fifty rats were randomly divided into a control group, a model group, a BMSCs group, a BMSCs + empty body group, and a BMSCs + IGF-1 group using a random number table method, with 10 rats in each group. We evaluated cartilage repair using the O'Driscoll scoring system and Mankin's scoring system. HE staining was used to observe pathological changes in cartilage tissue. qRT-PCR and Western blot were used to detect the expression levels of cartilage repair-related genes OC, GSK-3β, and Runx2 in various cartilage tissues.
