    Insights

    Recurrent mutations in PTPRB and PLCG1 genes were found in angiosarcomas. These genetic alterations may play a role in the development of this rare cancer.

    Area of Science:

    • Oncology
    • Genetics
    • Molecular Biology

    Background:

    • Angiosarcomas are rare, aggressive cancers originating from blood or lymph vessels.
    • Understanding the genetic underpinnings of angiosarcoma is crucial for developing targeted therapies.

    Purpose of the Study:

    • To identify recurrent genetic mutations in angiosarcoma tumors.
    • To investigate the potential role of identified mutations in angiosarcoma pathogenesis.

    Main Methods:

    • Whole-exome sequencing or targeted gene sequencing of angiosarcoma tumor samples.
    • Bioinformatic analysis to identify recurrently mutated genes.

    Main Results:

    • Recurrent mutations were identified in the PTPRB (protein tyrosine phosphatase, receptor type B) gene.
    • Recurrent mutations were also identified in the PLCG1 (phospholipase C gamma 1) gene.

    Conclusions:

    • PTPRB and PLCG1 mutations are recurrent in angiosarcomas.
    • These genetic alterations represent potential drivers of angiosarcoma development and could be therapeutic targets.

    Mechanism of Angiogenesis01:10

    Mechanism of Angiogenesis

    Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

    Regulation of Angiogenesis and Blood Supply

    Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

    Rous Sarcoma Virus (RSV) and Cancer

    Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
    RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

    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...

    Cancer-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.
    Such genes that act...
