Abstract
The development of heart disease involves interconnected factors such as oxidative stress, inflammation, and vascular dysfunction. Andrographolide (AG), known for its potent antioxidant and anti-inflammatory properties, has the potential to counteract lipopolysaccharides (LPS)-induced endothelial dysfunction by reducing oxidative stress and inflammation. Our research aimed to investigate the effects of AG on alleviating vascular endothelium dysfunction, oxidative stress, and inflammation in an experimental model induced by LPS. To create chronic vascular endothelium dysfunction, inflammation, and oxidative stress, rats received weekly injections of LPS via their tail vein over a 6-week period. The study evaluated the therapeutic effects of orally administered AG (50 mg/kg/day) on diseased conditions. We conducted aortic histology and measured nitric oxide (NO) thresholds, superoxide dismutase (SOD) activity, constitutive nitric oxide (cNOS) activity, and inducible nitric oxide (iNOS) levels, alongside several inflammatory biomarkers. To evaluate endothelial dysfunction, we assessed endothelium-dependent and endothelium-independent vasorelaxation in aortas through histopathological and various immunoassays examinations. Vascular Endothelial inflammatory activity was consequently enhanced in LPS groups animals when compared to normal control, also endothelial performance were dependently improved by AG therapy. IL-1β and tumors necrosis factor levels in the aorta decreased in a dose-dependent manner after exogenous AG delivery to LPS-treated rats. However, in current research work aortic SOD activity, NO levels, and cNOS activity increased, whereas aortic malondialdehyde levels and iNOS activity decreased after the AG treatment. These findings suggest that long-term AG therapy could be considered as a potential therapy to avoid vascular endothelial dysfunction and major nonobstructive coronary artery disease.

Abstract
BACKGROUND AND AIMS Aberrant acinar to ductal metaplasia (ADM), one of the earliest events involved in exocrine pancreatic cancer development, is typically studied using pancreata from genetically engineered mouse models. METHODS We used primary, human pancreatic acinar cells from organ donors to evaluate the transcriptional and pathway profiles during the course of ADM. RESULTS Following 6 days of three-dimensional culture on Matrigel, acinar cells underwent morphological and molecular changes indicative of ADM. mRNA from 14 donors' paired cells (day 0, acinar phenotype and day 6, ductal phenotype) was subjected to whole transcriptome sequencing. Acinar cell specific genes were significantly downregulated in the samples from the day 6 cultures while ductal cell-specific genes were upregulated. Several regulons of ADM were identified including transcription factors with reduced activity (PTF1A, RBPJL, and BHLHA15) and those ductal and progenitor transcription factors with increased activity (HNF1B, SOX11, and SOX4). Cells with the ductal phenotype contained higher expression of genes increased in pancreatic cancer while cells with an acinar phenotype had lower expression of cancer-associated genes. CONCLUSION Our findings support the relevancy of human in vitro models to study pancreas cancer pathogenesis and exocrine cell plasticity.
