Overexpression of miR-199a and miR-497 led to a statistically significant decrease in viable cells in a dose-dependent fashion after exposure to rituximab and various chemotherapeutics relevant in multi-agent lymphoma therapy. Our data indicate that elevated miR-199a and miR-497 levels are associated with improved survival in aggressive lymphoma patients most likely by modifying drug sensitivity to immunochemotherapy. This functional impairment may serve as a potential novel therapeutic target in future treatment of patients with DLBCL. Overexpression of the individual miRNAs did not result in any difference in cell viability, cell growth or apoptosis.

Unusual Activation of Pro-survival Pathway (UAPP)

Key Molecule: Neurogenic locus notch homolog protein 1 (NOTCH1) [8]

• Molecule Alteration: Mutation; .
• Resistant Disease: Chronic lymphocytic leukemia [ICD-11: 2A82.0]
• Experimental Note: Identified from the Human Clinical Data

• Experiment for Molecule Alteration: Next-generation sequencing assay

• Mechanism Description: Mutations in NOTCH1 result in increased stability of an activated intracellular NOTCH1 isoform, which confers cell survival and apoptosis resistance, in part by sustaining expression of the anti-apoptotic protein Mcl-1, and promoting the activity of the key translational regulator eIF4E. Compared with wild-type cases, NOTCH1-mutated cases have progressive disease and significantly shorter survival, and demonstrate resistance to the anti-CD20 monoclo.l antibody rituximab, a phenotype thought to be associated with the low CD20 levels and dysregulation of histone deacetylases(HDAC)-mediated epigenetic repression of CD20 expression observed in NOTCH1-mutated CLL.

B cell lymphoma [ICD-11: 2A86]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Aberration of the Drug's Therapeutic Target (ADTT)

Key Molecule: B-lymphocyte antigen CD20 (CD20) [3]
