As an interstitial fibrosis disease characterized by diffuse alveolitis and structural alveolar disorders, idiopathic pulmonary (IPF) has high lethality but lacks limited therapeutic drugs. A hospital preparation used for the treatment of viral pneumonia, Qingfei Tongluo mixture (QFTL), is rumored to have protective effects against inflammatory respiratory disease. This study aims confirm whether it a effect on bleomycin-induced IPF in rats elucidate its mechanism action. Male SD were...

Recently, there has been a noticeable increase in disorders of the female reproductive system, accompanied by rise adverse pregnancy outcomes. This trend is increasingly being linked to environmental pollution, particularly through lens Endocrine Disrupting Chemicals (EDCs). These external agents disrupt natural processes hormones, including synthesis, metabolism, secretion, transport, binding, as well elimination. disruptions can significantly impair human functions.

Small molecule BH3 mimetics comprise a promising new chemotherapeutic strategy for treating relapsed or chemoresistant cancer. In this study, we investigated the cellular mechanism of action by which BM-1197, Bcl-xL/Bcl-2 dual inhibitor, triggers apoptosis in panel colorectal cancer (CRC) lines. Using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays, determined that BM-1197 inhibited CRC cell growth concentration- and time-dependent manner. The 50 % inhibitory...

The human epidermal growth factor receptor-2 (ERBB2; formerly HER2)isoform ERBB2ΔEx16 (ERBB2d16) was oncogenic by mediating epithelial-mesenchymal transition (EMT), immune evasion, and resistance cell death to the anti-HER2 (trastuzumab) therapy. However, its physiological implications in gastric cancer were unclear. In this study, we examined a total of 110 patients with either locally advanced or metastatic HER2+ for expression ERBB2d16 EMT markers, infiltration CD3+ T cells tumor tissues,...
