Since our collection of cell lines is completely genetically annotated — which means that mutations and expression changes in each line's genes have been documented — we should be able to identify in advance patients who will benefit from specific combinations.

For extended modules, many different combinations of perturbed genes could incapacitate the module, as a result of which mutations in different genes will appear to lead to the same phenotype (e.g., hypertrophic cardiomyopathy).

One commonly held theory is that autism results from the chance combinations of commonly occurring gene mutations, which are otherwise harmless.

This study is intended to evaluate whether the combinations of these drugs are effective in the treatment of 2 different types of metastatic melanomas depending on whether there is a mutation of the BRAF gene.

We conclude that the large number of mouse mutants and human de novo mutations may be due to the combination of the Chd7 gene being a large target and the fact that many heterozygous carriers of the mutations are viable individuals with a readily detectable phenotype.

They identified several causal variations in CCDC115 gene: a homozygous missense mutation, c. 92T > C (p.Leu31Ser) and this one was also compound heterozygous in combination with a heterozygous deletion of CCDC115 (in one family) and a homozygous missense mutation, c. 31G > T (p.Asp11Tyr).

Invivoscribe's clinical laboratories also offer comprehensive MyAML ®, MyHeme ®, MyMRD ®, and custom gene panels, that when used in combination with Invivoscribe's proprietary MyInformatics ® Software can identify and track primary driver mutations as well as the subclonal architecture and emergence of new driver mutations in patients with hematologic disease.

This is in accordance with previous reports that decitabine and 5 - azacytidine produce a marked synergistic effect in combination with suberoylanilide hydroxamic acid and romidepsin in T - lymphoma cell lines by modulating cell cycle arrest and apoptosis.26, 27 As a mechanism of action, KMT2D mutations of B - lymphoma cells promote malignant outgrowth by perturbing methylation of H3K4 that affect the JAK - STAT, Toll - like receptor, or B - cell receptor pathway.28, 29 Here our study indicated that dual treatment with chidamide and decitabine enhanced the interaction of KMT2D with the transcription factor PU.1, thereby inactivating the H3K4me - associated signaling pathway MAPK, which is constitutively activated in T - cell lymphoma.13, 30,31 The transcription factor PU.1 is involved in the development of all hematopoietic lineages32 and regulates lymphoid cell growth and transformation.33 Aberrant PU.1 expression promotes acute myeloid leukemia and is related to the pathogenesis of multiple myeloma via the MAPK pathway.34, 35 On the other hand, PU.1 is also shown to interact with chromatin remodeler and DNA methyltransferease to control hematopoiesis and suppress leukemia.36 Our data thus suggested that the combined action of chidamide and decitabine may interfere with the differentiation and / or viability of PTCL - NOS through a PU.1 - dependent gene expression program.
