Identification of mechanisms underlying sensitivity and response to targeted therapies, such as the BRAF inhibitor vemurafenib, is critical in order to improve efficacy of these therapies in the clinic and delay onset of resistance. Glycolysis has emerged as a key feature of the BRAF inhibitor response in melanoma cells, and importantly, the metabolic response to vemurafenib in melanoma patients can predict patient outcome. Here, we present a multiparameter genome-wide siRNA screening dataset of genes that when depleted improve the viability and glycolytic response to vemurafenib in BRAF mutated melanoma cells. These datasets are suitable for analysis of genes involved in cell viability and glycolysis in steady state conditions and following treatment with vemurafenib, as well as computational approaches to identify gene regulatory networks that mediate response to BRAF inhibition in melanoma.

Background: Pediatric low-grade gliomas (pLGGs) have an overall survival of over 90%; however, patients harboring a BRAF alteration may have worse outcomes, particularly when treated with classic chemotherapy. Combined BRAF/MEK inhibition following incomplete resection demonstrated improved outcome in BRAF altered pLGG compared to combined carboplatin/vincristine chemotherapy and is now considered the standard FDA-approved treatment for this group of tumors. The aim herein was to investigate the efficacy and tolerability of single agent BRAF inhibitor treatment in BRAF altered pLGG.

BRAF mutation leads to constitutive activation of the MAPK pathway and is associated with the immune-activating molecular subtype of colorectal cancer. Targeted therapy for mutant metastatic colorectal cancer (CRC) has significantly improved outcomes for these patients when combined with anti-epithelial growth factor receptor (EGFR) therapy. However, most patients ultimately develop disease progression.

: Although BRAF inhibitors, such as vemurafenib, produce a marked response in patients with advanced melanoma with a BRAF V600 mutation, they eventually develop resistance to this treatment. To address this issue, vemurafenib is increasingly combined with the MEK inhibitor cobimetinib, leading to improved response rates and enhanced survival. However, this treatment modality is associated with numerous side effects.

BRAF inhibitors (BRAFi) represent a cornerstone in melanoma therapy due to their high efficacy. However, the emergence of resistance causes a significant challenge to their clinical utility. This study aims to investigate the potential of diclofenac as a sensitizer for BRAFi therapy in melanoma and to elucidate its underlying mechanism.

Erdheim-Chester disease (ECD) is a non-LCH, characterized by multi-organ involvement, typical imaging findings, and confirmatory histological studies. A case with multi-organ involvement and histological confirmation is presented.
