Amplification leads to an excess production of HER2 protein while deletion results in reduced levels. Both scenarios disrupt normal signaling pathways involved in controlling cell proliferation and survival.
On the other hand, tumor suppressor genes act as guardians against uncontrolled cell growth by inhibiting tumor formation through various mechanisms such as DNA repair regulation or inducing programmed cell death (apoptosis). Loss-of-function mutations caused by chromosomal deletions can render these protective genes inactive.
The TP53 gene (also known as p53) is often referred to as “the guardian of the genome” due to its critical role in preventing abnormal cells from proliferating uncontrollably. However, TP53 is frequently mutated or deleted in many types of cancer.
Chromosome 17p deletion, where TP53 resides, can lead to the loss of its tumor-suppressing function and contribute to cancer development.
Understanding the specific genes affected by chromosome deletions in different cancers is crucial for developing targeted therapies. Advances in genomic technologies have enabled researchers to identify these alterations more accurately and efficiently than ever before.
For instance, next-generation sequencing techniques allow scientists to analyze entire genomes or specific regions of interest with unprecedented precision. By comparing the genetic profiles of tumor cells with normal cells from the same individual, researchers can pinpoint chromosomal deletions that may be driving cancer progression.
Furthermore, recent studies have shown promising results using gene editing tools like CRISPR-Cas9 to correct chromosomal deletions in oncogenNavient is one of the largest student loan servicers in the United States, managing loans for millions of borrowers.
