Finally, we also found that CDKN2A deletion negatively correlated with the expression of T-cell markers in many other cancer types. In conclusion, CDKN2A deletion could inhibit T cell infiltration by inhibiting chemokine expression in a cell cycle dependent manner.

In conclusion, CDKN2A deletion could inhibit T cell infiltration by inhibiting chemokine expression in a cell cycle dependent manner. Model explaining how CDKN2A deletions are generated. In this model we propose that the HDs arise in two steps. In the first step, one of the homologues (Homologue 2) may sustain a deletion (the whole arm or interstitial) leading to a LOH. A second break may occur due to interference between replication forks and MTAP or other genes (MIR31HG, CDKN2A).

Detection of homozygous deletions of CDKN2A (also called p16) by FISH is useful to distinguish malignant pleural mesothelioma (MPM) and diffuse malignant peritoneal mesothelioma (DMPM) from reactive mesothelial hyperplasia (RMH) and epithelial ovarian cancer (EOC). 2017-06-19 · CDKN2A (or CDKN2A/B) homozygous deletion was identified as the sole driver alteration in 1.2% (16 of 1,322) RCC cases and also in other disease types, including 15.2% of salivary gland acinic cell tumors, 14.3% of bone giant-cell tumors, and 11.3% of bone chordomas (Table 1). 2020-10-20 · High percentage CDKN2A homozygous deletion is a rare event in primary IDHm astrocytomas and is more common in recurrent tumors. a shows the frequency distribution of the percent of tumor cells with homozygous CDKN2A deletion by FISH in primary IDHm astrocytomas (n = 108). Finally, we also found that CDKN2A deletion negatively correlated with the expression of T-cell markers in many other cancer types. In conclusion, CDKN2A deletion could inhibit T cell infiltration by inhibiting chemokine expression in a cell cycle dependent manner.

2008-08-01 · Some studies have suggested that CDKN2A deletion is a poor prognostic factor , , , , whereas such correlation has not been found by others , . In addition to deletions, the CDKN2A locus can also be inactivated by hypermethylation of the CpG islands in the promoter region or by point mutations, both resulting in gene silencing . that the prevalence of CDKN2A deletion in malignant mesothe-lioma is up to 72% among primary tumors and may be even higher in mesothelioma cell lines (7–9). In addition, as in other cancer types, studies of mesothelioma have described CDKN2A promoter methylation as an alternative mechanism of CDKN2A inactivation in some nondeleted cases (10). 2020-07-08 · In addition, homozygous focal deletions of the cyclin-dependent kinase inhibitor 2A (CDKN2A) gene, located at 9p21, have been observed at high frequency in anaplastic meningiomas [1, 3, 4, 9, 13].
