Splet13. sep. 2011 · Overexpression of Pdx1 protein resulted in an upregulation of Ins1 and Ins2 mRNA expression seen as early as day 10 for Ins1 and day 14 for Ins2, and they reached maximum levels at day 17 ( Fig. 1A ). Ins1 is express only in pancreas, whereas Ins2 is expressed in both pancreas and brain [26], [27]. Splet01. jun. 2009 · Overexpression of Pdx1 in mouse pancreatic ductal cells (PDCs) was sufficient to activate endogenous Ngn3 mRNA levels as compared with cells transduced with the empty vector (Figure 5 B). Figure 5 Pdx1 regulates Ngn3, at least in part, via its direct occupancy of a conserved upstream enhancer of Ngn3.
Splet10. mar. 2024 · Pancreatic cancer is driven by risk factors such as diabetes and chronic pancreatic injury, which are further associated with gut dysbiosis. Intestinal toxins such as bile acids and bacterial endotoxin (LPS), in excess and persistence, can provoke chronic inflammation and tumorigenesis. Of interest is that many intestinal toxins are negatively … Preferential overexpression in PDX1 LOW /MAFA LOW (immature) β-cells was confirmed using Pdx1-BFP reporter islets 26, which read out endogenous Pdx1 levels.

Splet28. jan. 2024 · On the other hands, pancreatic and duodenal homeobox factor 1 (Pdx1) is an important transcription factor for various β-cell-related genes including insulin gene and thereby contributes to the maintenance of mature β-cell function. The aim of this study was to evaluate how Ffar1 expression in β-cells is altered under diabetic conditions. Splet29. dec. 2010 · However, Pdx1 overexpression upregulated Mafa mRNA expression, increased insulin content and increased insulin secretion in both low and high glucose concentrations. The expression patterns of Mafa and Pdx1 during the neonatal period were distinct even though both have been implicated in regulating expression of the other [13, …
Splet29. jan. 2024 · In addition, Pdx1 overexpression in vitro revealed that Pdx1 plays a role in maintaining β-cell phenotypes [20]. Thus, among the extensive in vitro and in vivo studies performed, there have been no direct in vivo studies showing whether the sustained expression of Pdx1 in β cells protects or improves β-cell function under diabetic …
