The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.8K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

13.6K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

The Ras Gene02:38

The Ras Gene

7.4K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Area of Science:

  • Genetics and developmental biology.
  • Investigating the genetic underpinnings of rare skin and congenital disorders.

Background:

  • The etiology of Becker's nevus and Becker's nevus syndrome remains largely unknown.
  • Previous research has not identified the specific genetic causes for these conditions.

Purpose of the Study:

  • To elucidate the genetic basis of Becker's nevus and Becker's nevus syndrome.
  • To explore potential molecular pathways involved in these disorders.

Main Methods:

  • Genetic analysis of affected individuals.
  • Investigating the role of the ACTB gene and beta-actin protein.
  • Exploring potential links to the Hedgehog signaling pathway.

Main Results:

  • Evidence suggests lethal mutations in the ACTB gene, coding for beta-actin, cause these disorders.
  • These ACTB mutations may disrupt Hedgehog pathway signaling.
  • Findings provide a genetic explanation for Becker's nevus and related syndromes.

Conclusions:

  • ACTB gene mutations are implicated in the etiology of Becker's nevus and Becker's nevus syndrome.
  • Disruption of beta-actin function and Hedgehog signaling are potential mechanisms.
  • This research opens new avenues for clinical genetics and hair research.
