RAS GENES Meaning and
Definition
-
Ras genes refer to a group of proto-oncogenes that play a vital role in controlling cell growth and division. Proto-oncogenes are normal genes present in all cells that can be mutated or altered to become oncogenes, which are genes that contribute to the development of cancer.
The ras genes encode proteins called Ras proteins, which act as molecular switches within the signaling pathways that regulate cell growth, differentiation, and survival. These proteins are involved in transducing extracellular signals from growth factors to the cell nucleus, where they help control gene expression and coordinate cellular responses.
Mutations in ras genes can lead to the constitutive activation of Ras proteins, causing dysregulation of cell signaling and promoting uncontrolled cell growth. Such mutations are commonly found in various types of cancers, including pancreatic, lung, and colorectal cancer. The mutated Ras proteins continuously transmit growth signals, driving the abnormal proliferation of cancer cells and hindering the body's ability to regulate cell growth and division.
Due to their prominent role in cancer development, ras genes have been extensively studied, and targeted therapies have been developed to inhibit the function of mutant Ras proteins. These therapies aim to restore normal signaling and halt cancer progression. However, the high prevalence of Ras mutations and the complexity of Ras signaling pathways pose significant challenges in the development of effective treatments for Ras-driven cancers.
