Abstract:
Aim- pancreatic ductal adenocarcinoma is one of the most aggressive oncological disease with early metastasis and high mortality rate. CSF1R is a gene with progenitor activity, which is also associated with different malignant diseases. In this study our objective was to analyze expression of CSF1R in pancreatic cancer tissues and nerve invasive cancer cells. Quantitative real time polymerase chain reaction (QRT-PCR) was used to analyze the expression of CSF1R mRNA in nine cultured pancreatic cancer cell lines and pancreatic bulk tissues of the normal pancreas, chronic pancreatitis (n=20/20) and pancreatic ductal adenocarcinoma (n=58). Nerve invasive clones of two pancreatic cancer cell lines was also used. QRT-PCR analysis revealed a significant up-regulation of CSF1R mRNA expression in pancreatic adenocarcinoma tissues compared to normal tissues and low expression of this gene indicated a tendency for better survival of pancreatic cancer patients. Expression of CSF1R mRNA was present in all tested pancreatic cancer cell lines with comparably low to moderate expression levels. The CSF1R was significantly overexpressed in nerve invasive pancreatic cancer cells. Increased expression of CSF1R in pancreatic cancer might be related to perineural invasion and poor prognosis. CSF1R might be an important factor during the development and malignant transformation of tissues.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
