Insights

Genetic mutations in the CASP3 gene, crucial for apoptosis, were found in various human tumors. These CASP3 gene alterations suggest its occasional role in cancer development.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Apoptosis, or programmed cell death, is a critical process often disrupted in cancer.
  • Caspase-3 is an executioner caspase essential for apoptosis, making its gene (CASP3) a candidate for cancer-related mutations.

Purpose of the Study:

  • To investigate somatic mutations within the CASP3 gene across a wide spectrum of human tumors.
  • To determine if genetic alterations in CASP3 contribute to the development of various human cancers.

Main Methods:

  • Analysis of the entire coding region and splice sites of the human CASP3 gene.
  • Screening for somatic mutations in 944 tumor samples from diverse cancer types.

Main Results:

  • Fourteen distinct somatic mutations were identified in the CASP3 gene.
  • Mutations included missense, silent, intronic, and untranslated region alterations.
  • CASP3 mutations were detected in colon, non-small cell lung, non-Hodgkin lymphoma, stomach, hepatocellular, and multiple myeloma tumors.

Conclusions:

  • This study provides the first evidence of CASP3 gene mutations in human tumors.
  • The CASP3 gene is occasionally altered in human cancers, suggesting a potential role in tumorigenesis.

Caspases01:24

Caspases

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside cells.
Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

The Ras Gene02:38

The 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.
Ras is a superfamily...
Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
Somatic cells are...
Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

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.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
