Dual farnesyl and geranylgeranyl transferase inhibitor thwarts mutant KRAS-driven patient-derived pancreatic tumors
Purpose: Mutant KRAS is a major driver of pancreatic oncogenesis and therapy resistance, yet KRAS inhibitors are lacking in the clinic. KRAS requires farnesylation for membrane localization and cancer-causing activity prompting the development of farnesyltransferase inhibitors (FTIs) as anti-cancer agents. However, KRAS becomes geranylgeranylated and active when cancer cells are treated with FTIs. To overcome this geranylgeranylation-dependent resistance to FTIs, we designed FGTI-2734, a RAS C-terminal...

Radiosensitization by Histone H3 Demethylase Inhibition in Diffuse Intrinsic Pontine Glioma
Purpose: Radiation therapy (RT) has long been and remains the only treatment option for diffuse intrinsic pontine glioma (DIPG). However, all patients show evidence of disease progression within months of completing radiation therapy. No further clinical benefit has been achieved using alternative radiation strategies. Here we tested the hypothesis that histone demethylase inhibition by GSK-J4 enhances radiation-induced DNA damage, making it a potential radiosensitizer in the treatment of DIPG....

Sensitive and quantitative probing of pseudouridine modification in mRNA and long non-coding RNA [Method]
Pseudouridine () is the most abundant RNA modification in cellular RNA present in tRNA/rRNA/snRNA and also in mRNA and long non-coding RNA. Elucidation of function in mRNA/lncRNA requires mapping and quantitative assessment of its modification fraction at single-base resolution. The most widely used mapping method for mRNA/lncRNA relies on its reaction with N-Cyclohexyl-N'-(2-morpholinoethyl)carbodiimide (CMC), forming an adduct with the base in RNA that is detectable by reverse transcription...

Anti-Leukemia Effects of Notch-Mediated Inhibition of Oncogenic PLK1 in B-Cell Acute Lymphoblastic Leukemia
In B cell acute lymphoblastic leukemia (B-ALL), activation of Notch signaling leads to cell-cycle arrest and apoptosis. We aimed to harness knowledge acquired by understanding a mechanism of Notch-induced cell death to elucidate a therapeutically viable target in B-ALL. To this end, we identified that Notch activation suppresses Polo-like kinase 1 (PLK1) in a B-ALL specific manner. We identified that PLK1 is expressed in all subsets of B-ALL, and is highest in Philadelphia-like (Ph-like) ALL,...

Paraneoplastic and Therapy-Related Immune Complications in Thymic Malignancies
Opinion statement The thymus is a key organ involved in establishing central immune tolerance. Thymic epithelial tumors (TETs) include thymomas and thymic carcinomas. Thymomas, which are histologically distinct from thymic carcinomas, lead to dysregulated thymopoiesis via decreased thymic epithelial expression of AIRE and MHC Class II, as well as via alterations in thymic architecture, thereby resulting in autoimmune complications that manifest as paraneoplastic disorders (PNDs)....
