Glossary Oncogenic Mutations

changes in DNA that can lead to cancer

Oncogenic mutations, also known as cancer-causing mutations, are changes in the DNA that can transform a normal cell into a cancerous one. These mutations often occur in genes that regulate cell growth, division, and death, such as oncogenes and tumor suppressor genes, leading to uncontrolled cell proliferation and tumor formation.

research LB1011 Oncogenic ras mutation induces spatiotemporally specific tissue deformation through converting fluctuated into sustained ERK activation

July 2022 in “Journal of Investigative Dermatology”

This study found that the KrasG12D mutation alters ERK signal dynamics in hair follicle stem cells, leading to tissue deformation, and suggests a collective effect of mutant cells is necessary for disruption.

research Oncogenic Kras induces spatiotemporally specific tissue deformation through converting pulsatile into sustained ERK activation

September 2022 in “bioRxiv (Cold Spring Harbor Laboratory)”

In this study, researchers using live mice observed that oncogenic Kras mutation disrupts hair follicle architecture by sustaining ERK signal activation, which affects stem cell behavior and tissue integrity.

research Expanding phenotype of hereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis caused by FAM111B mutations: Report of an additional family raising the question of cancer predisposition and a short review of early-onset poikiloderma

23 citations , March 2017 in “JAAD case reports”

This study reports a new family with hereditary fibrosing poikiloderma (POIKTMP) and identifies a pancreatic cancer occurrence in a family member, raising questions about FAM111B's role as a potential cancer predisposition gene.

research Author response: Crosstalk with keratinocytes causes GNAQ oncogene specificity in melanoma

November 2021

This study found that the survival and proliferation of mouse melanocytes expressing the GNAQQ209L oncogene were impaired by interactions with the epidermal microenvironment, suggesting a possible mechanism for the rarity of these mutations in epidermal melanomas.
