Abstract

Gastric cancer is a common global malignancy that requires detailed study of its development mechanisms. Although LncRNA FIRRE is known to play a crucial role in the progression and treatment resistance of several cancers, its effect on gastric cancer is not well understood. This study confirms the impact of FIRRE on the malignant behavior of gastric cancer. Using RNA-sequencing, dual luciferase reporter assay, RIP and CHIP, we identified transcription factors and target genes linked to FIRRE. Elevated FIRRE expression in gastric cancer correlates with worse patient prognosis and promotes gastric cancer proliferation, migration, and invasion both in vitro and in vivo. FIRRE regulates the TUBB3 gene, facilitating gastric cancer progression by activating the TUBB3 promoter in vitro. ZFP64 is the transcription factor for TUBB3, activating its promoter and binding specifically with FIRRE. Reducing ZFP64 disrupts FIRRE's positive regulation of TUBB3 in vitro and in vivo. This study shows FIRRE promotes gastric cancer progression by binding to ZFP64 and activating the TUBB3 promoter.

期刊介绍： Cancer Letters is a reputable international journal that serves as a platform for significant and original contributions in cancer research. The journal welcomes both full-length articles and Mini Reviews in the wide-ranging field of basic and translational oncology. Furthermore, it frequently presents Special Issues that shed light on current and topical areas in cancer research. Cancer Letters is highly interested in various fundamental aspects that can cater to a diverse readership. These areas include the molecular genetics and cell biology of cancer, radiation biology, molecular pathology, hormones and cancer, viral oncology, metastasis, and chemoprevention. The journal actively focuses on experimental therapeutics, particularly the advancement of targeted therapies for personalized cancer medicine, such as metronomic chemotherapy. By publishing groundbreaking research and promoting advancements in cancer treatments, Cancer Letters aims to actively contribute to the fight against cancer and the improvement of patient outcomes.
