Summary
Functional genomic screens rapidly prioritize glioblastoma (GBM) cancer genes. Researchers identified six candidate GBM oncogenes, validating RINT1 as a novel oncogene conferring tumorigenicity in vivo.
Area of Science:
- Oncology
- Genomics
- Cancer Biology
Background:
- Large-scale cancer genomics projects identify numerous somatic genomic alterations in glioblastoma (GBM).
- Differentiating driver mutations from passenger mutations necessitates functional validation of each gene.
- Prioritizing genomic alterations requires integrating biological evidence with statistical significance.
Purpose of the Study:
- To demonstrate the feasibility of in vitro functional genomic screens for systematically prioritizing candidate GBM genes.
- To identify high-probability oncogenes for further in vivo validation.
Main Methods:
- Utilized low-complexity gain- and loss-of-function screens based on genomic data.
- Integrated in vitro functional screening with large-scale cancer genomics data.
- Conducted in vivo validation of candidate genes.
Main Results:
- Identified six candidate glioblastoma (GBM) oncogenes through integrated genomic and functional screening.
- Validated RINT1 as a novel GBM oncogene.
- Demonstrated RINT1's ability to confer tumorigenicity to primary murine astrocytes in vivo.
Conclusions:
- Cancer genomics-guided functional screens offer a rapid method for prioritizing high-value targets.
- This approach facilitates downstream mechanistic and translational studies in glioblastoma research.

01:20The Retinoblastoma Gene
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,...

03:18Non-LTR Retrotransposons
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...
02:38The Ras Gene
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.

02:39lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
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.
