It may become a oncogene.

An oncogene is a mutated gene with the ability to cause cancer. A proto-oncogene is a gene that regulates normal cell division before it becomes mutated into an oncogene. These genes are frequently mutated or overexpressed in tumor cells. When critical functions are altered or malfunctioning, most normal cells will endure a programmed form of rapid cell death.

Oncogenes are a structurally and functionally diverse group of genes, the protein products of which act pleiotropically and influence multiple complex regulatory cascades inside the cell. They govern cell proliferation, growth, and differentiation, in addition to cell cycle and apoptosis control.

DENIUS [597]

The inner layer of the serosal pericardium is a thin, transparent layer of simple squamous epithelium called the "visceral pericardium."

<h3>What is serosal pericardium?</h3>

A fibrous pericardium (parietal covering), which would be mirrored around the roots of the main veins to cover the whole surface of the heart, is lined by a layer of serosa called the serous pericardium (visceral layer).

Some key features of serosal pericardium are-

  • There might be a little hole between the parietal & visceral layers that a small quantity of fluid might fill.
  • The epicardium is the region of a visceral layer which surrounds the heart but not the major vessels.
  • There are two sinuses formed by the serous pericardium as it reflects off different cardiac structures: the transverse sinus as well as the oblique sinus.
  • A cul-de-sac formed by two left pulmonary circulation on one side and also the two pulmonary artery veins on the other, the oblique sinus extends superiorly from of the inferior vena cava.
  • In between four pulmonary veins, its posterior wall of a left atrium forms its anterior wall. The left atrium has room to expand thanks to the oblique sinus.
  • The visceral serosal pericardium is reflected from the posterior portions of the pulmonary and aortic veins onto the superior surface of the atrium to produce the transverse sinus, which is open at both ends.
