Article Abstract

B7-H3 is a common oncogene found in various cancer types. However, the molecular mechanisms underlying abnormal B7-H3 expression and colorectal cancer (CRC) progression need to be extensively explored. B7-H3 was upregulated in human CRC tissues and its abnormal expression was correlated with a poor prognosis in CRC patients. Notably, gain- and loss-of-function experiments revealed that B7-H3 knockdown substantially inhibited cell proliferation, migration, and invasion , whereas exogenous B7-H3 expression yielded contrasting results. In addition, silencing of B7-H3 inhibited tumor growth in a xenograft mouse model. Mechanistically, our study demonstrated that the N6-methyladenosine (m6A) binding protein YTHDF1 augmented B7-H3 expression in an m6A-dependent manner. Furthermore, rescue experiments demonstrated that reintroduction of B7-H3 considerably abolished the inhibitory effects on cell proliferation and invasion induced by silencing YTHDF1. Our results suggest that the YTHDF1-m6A-B7-H3 axis is crucial for CRC development and progression and may represent a potential therapeutic target for CRC treatment.

NUTM2A-AS1 is an emerging long noncoding RNA (lncRNA) that has garnered significant attention due to its multifaceted roles in cancer biology. As a member of the ceRNA network, NUTM2A-AS1 modulates gene expression by sequestering microRNAs, thereby influencing key oncogenic pathways. This review aims to provide a comprehensive overview of the current understanding of NUTM2A-AS1 in the development, progression, and metastasis of various cancers, including gastric cancer, hepatocellular carcinoma, neuroblastoma, colorectal cancer, glioma, lung adenocarcinoma, prostate cancer, and renal cell carcinoma.

Background: Triple-negative breast cancer (TNBC) represents a subtype of breast cancer with poorest prognosis due to limited effective targeted therapies. Chimeric antigen receptor T cell (CAR-T) therapy has shown remarkable efficacy in treating hematological cancers, but its application in TNBC requires further development. One major obstacle is the lack of suitable tumor-specific target in TNBC.

Anaplastic thyroid carcinoma (ATC) represents a rare yet highly malignant histotype of thyroid cancer. Cancer-associated fibroblasts (CAFs) play a pivotal role in tumor cell invasion, migration, and angiogenesis and present a potential target for cancer treatment. We aimed to investigate the effects of modulating specific subsets of CAFs on the proliferation, invasion, and migration of ATC.

Small-cell lung cancer (SCLC) is a tobacco-associated neuroendocrine tumor comprising ~15% of lung cancers (~150,000 cases/year). For decades, outcomes stagnated: most patients present with extensive-stage disease, screening rarely detects early tumors, surgery is seldom feasible, and platinum-etoposide remained the first-line standard with median overall survival (OS) <12 months. Radiotherapy (including consolidative thoracic RT) and prophylactic cranial irradiation or MRI surveillance offered incremental gains.

Colorectal cancer (CRC) remains a leading cause of cancer-related morbidity and mortality worldwide. Despite advances in various treatment approaches, outcomes for patients with metastatic CRC (mCRC) remain poor, and treatment-associated side effects significantly impact quality of life. While immunotherapy has shown promise in certain malignancies, its efficacy in CRC is limited to a minority of patients, highlighting the urgent need for novel therapeutic targets to improve treatment efficacy while minimizing off-target effects.
