Sentence examples for mutations of oncogenes from inspiring English sources

68 An evaluation of 98 models or tumor samples of osteosarcoma showed very few point mutations of oncogenes and tumor suppressor genes commonly mutated in carcinomas; the PI3K pathway did emerge as a recurrently disrupted pathway in a subset of the patients.

Colorectal cancer develops from benign precursors, the adenomatous polyps; there is extensive evidence that polyps transform into cancer in a stepwise manner, and that several molecular abnormalities (mutations of oncogenes, inactivation of tumour suppressor genes and microsatellite instability) accompany and, somehow, determine colorectal tumourigenesis.

Considering the complex strategies developed by tumors to evade immune surveillance, pathological types of tumors, mutations of oncogenes and tumor suppressor genes, the stage of disease, and the number of TILs are all essential factors in determining the suitability of immunotherapy.

However, mutant allele specific imbalance (MASI) has been observed in tumors and cell lines harboring mutations of oncogenes.

In addition to genetic alterations involving mutations of oncogenes and TSGs, carcinogenic progression from benign neoplasm to adenocarcinoma can occur through epigenetic changes in gene promoters [5].

The suppressor pathway, observed in >80% of CRC cases, involves abnormalities of the APC/wingless signalling pathway and is characterized by frequent somatic mutations of oncogenes and loss of heterozygosity of tumor suppressor genes, chromosomal instability, and microsatellite stable (MSS) tumors.

The underlying cause of ampullary cancer is complex, involving mutation of oncogenes, silencing of tumor suppressors, alteration of cell adhesion molecules, and activation of tumor-associated macrophages [ 7– 9].

In cancer cells, the balance of cell death with survival is frequently disturbed by the mutation of oncogenes or tumor suppressor genes and by the alteration of signaling pathways [ 1].

Broad hypomethylation with focal hypermethylation are frequently found in cancer [ 8, 12], thus affecting the expression of tumor suppressor genes, e.g. TP53, DCC, SOCS2, DLEU7 [ 13- 16], and favoring the mutation of oncogenes [ 17].

While FH mutation has yet to be identified in sporadic tumors, NRF2 activation has been reported as a consequence of either direct NRF2 gain-of-function mutation, KEAP1 loss-of-function mutation, or gain-of-function mutation of oncogenes such as MYC, BRAF, and KRAS in disparate cancer types [32]– [32].

Analyses of hyperplastic synovial tissues of patients with RA reveal features of transformed long-living cells such as the presence of somatic mutations, expression of oncogenes, and resistance to apoptosis [ 1- 3].
