After ruxolitinib therapy, he later developed leukocytosis and 2% circulating blasts. Repeat marrow demonstrated ≥ 15% ring sideroblasts. Retrospectively, the initial biopsy fulfills ICC 2022 criteria for MDS/MPN-SF3B1-T, highlighting the diagnostic value of genetics-integrated classification in fibrotic marrows.
Overall, our findings suggest that TMZ may induce oncogenic miRNA expression as part of an adaptive response, while ruxolitinib may counteract this effect. Targeting miRNA-mediated regulatory networks in combination with pathway inhibition may represent a promising strategy to overcome therapeutic resistance in glioblastoma.

Knockdown of NTRK1, which encodes TrkA, reduced cell viability and sensitized ATC cells to paclitaxel. Entrectinib was well tolerated at the administered dose, with no significant changes in body weight and serum biochemical markers. Collectively, these findings identify TrkA as a potential therapeutic target in ATC and support further investigation of entrectinib-based combination strategies to improve ATC treatment outcomes.

NTRK1 (Neurotrophic tyrosine kinase, receptor, type 1)
Treatment strategies included supportive care, interferon, hydroxyurea, and ruxolitinib. PMF and SMF demonstrate distinct clinical phenotypes despite sharing bone marrow fibrosis as a common endpoint. The mutational landscape highlights the genetic heterogeneity of MF and underscores the importance of integrating clinical, pathological, and molecular information to improve disease characterization and guide individualized management.
