NRAS (Neuroblastoma RAS viral oncogene homolog)

OS was additionally negatively affected when the ten genes were unmutated. Notably, outcomes were excellent for SAR mutations (2-year LFS 76%, OS 84%), indicating allo-HCT in CR1 can overcome their adverse risk at diagnosis.

Moreover, FTY720 co-treatment resensitized G12D NRAS -mutated M14(R)701 cells to gilteritinib in vivo. Co-treatment inactivated ERK, transcriptionally downregulated SPHK1, and inactivated downstream AKT, p70S6K and BAD, with inactivation abrogated by constitutive SPHK1 expression. The clinically applicable S1PR modulators fingolimod and mocravimod resensitize NRAS -mutated FLT3-ITD AML cells to FLT3 inhibitors, supporting potential clinical efficacy of these combinations.

Here, we show that sotorasib, adagrasib, and the RAS-ON inhibitor RMC-6291 are effective in a neuroblastoma cell line altered by KRAS(G12C). Importantly, sotorasib also decreased ERK phosphorylation in a NRAS(G12C)-altered cell line xenograft model; however, this treatment did not prolong survival as a single agent. These results suggest that combinations of targeted agents that include sotorasib may be required for clinical benefit in pediatric patients with H- or NRAS(G12C)-altered malignancies in addition to those with KRAS(G12C)-altered malignancies.

The ferroptosis inducer erastin also inhibits melanoma growth. Combining the ATAD2 inhibitor BAY-850 with the MEK inhibitor trametinib potently suppresses melanoma growth. Our study identifies ATAD2 as a key driver of melanoma and provides a rationale for targeting ATAD2 in conjunction with the MAPK pathway to treat melanoma.

Clinically, one patient succumbed to disease one month and another patient experienced a recurrence at 43 months, whereas the remaining patients had no evidence of disease at 3-24 months of follow-up. MLA displays unique cytomorphologic features and accurate identification of MLA on cytology should prompt confirmatory tests to exclude potential morphologic mimics and ensure appropriate diagnosis.

Subsequently, multiple hepatic metastases and pelvic dissemination developed, and conventional chemotherapy including bevacizumab was ineffective...Switching to sorafenib led to further progression, but reintroduction of LVB reduced Tg levels...The patient has survived seven years since recurrence, including six years on LVB. The tumor behaved similarly to poorly differentiated thyroid carcinoma, with Tg levels reflecting disease activity and LVB demonstrating the potential for long-term tumor control.

This study identifies NCOA5 and CHD4 as crucial proviral cofactors and NRAS as a potent antiviral factor regulating HBV replication. The findings highlight HBV's profound host dependence, uncover specific molecular mechanisms (involving HNF4A, epigenetic regulation of cccDNA, and cell cycle), and reveal validated host targets for potential therapeutic strategies against HBV infection.

Mucosal and vulvovaginal melanomas are biologically and clinically distinct from cutaneous melanoma and continue to have poor survival outcomes. Their rarity restricts high-quality evidence, highlighting the need for collaborative, innovative research to inform effective treatment strategies.

This study delineated the genetic landscape of pAML in Southwest China and explored the prognostic value of gene fusions and mutations in early and long-term outcomes. These findings provide a foundation for understanding the genetic heterogeneity of pAML and offer evidence for the development of precision medicine approaches.

These data support RRAS Q87L and RRAS2 Q72L as bona fide lung cancer drivers and nominate RRAS/RRAS2-mutant tumors as candidates for pan-RAS-targeted therapeutics. Our findings provide a biologic rationale and preclinical evidence to inform molecular testing paradigms and to prioritize enrollment of patients with RRAS/RRAS2-mutant NSCLC into future clinical trials of pan-RAS inhibitors.
