Article Abstract
Pediatric low-grade gliomas (LGGs) frequently do not engraft in immunocompromised mice, limiting their use as an experimental platform. In contrast, murine Neurofibromatosis-1 () optic LGG stem cells (o-GSCs) form glioma-like lesions in wild-type, but not athymic, mice following transplantation. Here, we show that the inability of athymic mice to support o-GSC engraftment results from impaired microglia/macrophage function, including reduced expression of Ccr2 and Ccl5, both of which are required for o-GSC engraftment and optic glioma growth. Impaired Ccr2 and Ccl5 expression in athymic microglia/macrophages was restored by T-cell exposure, establishing T-cell-microglia/macrophage interactions as critical stromal determinants that support NF1 LGG growth.

Objective: CXCR4 and integrin αβ play important roles in tumor biology and are highly expressed in multiple types of tumors. This study aimed to synthesize, preclinically evaluate, and clinically validate a novel dual-targeted PET imaging probe Ga-pentixafor-c(RGDfK) for its potential in imaging tumors.
Methods: The effects of Ga-pentixafor-c(RGDfK) on cell viability, targeting specificity, and affinity were assessed in the U87MG cells.

Preferentially expressed antigen in melanoma (PRAME), which is highly expressed in melanoma, is associated with tumor progression and malignancy. Notably, melanoma cells often exhibit inactivation of the tumor suppressor p53 despite carrying the wild-type p53 gene. Here, we investigated the functional interplay between PRAME and p53.

Aberrant activation of fibroblast growth factor receptors (FGFRs) plays a critical role in tumorigenesis across multiple cancer types, driving the development of various FGFR inhibitors. Despite clinical advances, therapeutic efficacy remains limited by the emergence of drug resistance, primarily mediated by gatekeeper mutations in FGFRs. To overcome this challenge, we designed and synthesized a novel series of 7-(1-methyl-1-indole-3-yl)-5-pyrrolo[2,3-]pyrazine derivatives as covalent pan-FGFR inhibitors targeting both wild-type and gatekeeper mutants.
