MicroRNAs (miRNAs) that exert function by posttranscriptional suppression have recently brought insight in our understanding of the role of non-protein-coding RNAs in carcinogenesis and metastasis. In this study, we described the function and molecular mechanism of miR-139-5p in colorectal cancer (CRC) and its potential clinical application in CRC. We found that miR-139-5p was significantly downregulated in 73.8% CRC samples compared with adjacent noncancerous tissues (NCTs), and decreased miR-139-5p was associated with poor prognosis. Functional analyses demonstrated that ectopic expression of miR-139-5p suppressed CRC cell migration and invasion in vitro and metastasis in vivo. Mechanistic investigations revealed that miR-139-5p suppress CRC cell invasion and metastasis by targeting AMFR and NOTCH1. Knockdown of the two genes phenocopied the inhibitory effect of miR-139-5p on CRC metastasis. Furthermore, the protein levels of the two genes were upregulated in CRC samples compared with NCTs, and inversely correlated with the miR-139-5p expression. Increased NOTCH1 protein expression was correlated with poor prognosis of CRC patients. Together, our data indicate that miR-139-5p is a potential tumor suppressor and prognostic factor for CRC, and targeting miR-139-5p may repress the metastasis of CRC and improve survival.

Objective:To know the current situation of kinesiophobia in patients after cardiac surgery under cardiopulmonary bypass, and to clarify its influencing factors, so as to provide reference for developing intervention strategies to improve kinesiophobia level.Methods:This was a cross-sectional study. From February 2022 to September 2022, the patients after cardiac valve surgery under cardiopulmonary bypass in the Second Affiliated Hospital Zhejiang University School of Medicine were investigated by convenience sampling methods. The survey was conducted using the General Information Questionnaire, The Tampa Scale for Kinesiophobia Heart, Exercise Self-Efficacy Scale, Pain Catastrophizing Scale, and Adaptation, Partnership, Growth, Affection and Resolve(APGAR) as research tools, and the influencing factors were analyzed using univariate and binary Logistic regression analysis.Results:A total of 219 patients were included, of which 97 patients (44.3%) had kinesiophobia. The results of binary Logistic regression analysis showed that monthly family income level, first time out of bed after operation, fear of falling, the family APGAR, and pain catastrophizing were significant influencing factors of kinesiophobia in patients after heart valve surgery under cardiopulmonary bypass (all P<0.05). Conclusions:The prevalence of kinesiophobia is high among patients after heart valve surgery under cardiopulmonary bypass. Clinicians should pay attention to patients with low monthly family income level, late first time out of bed after surgery, and fear of falling, as well as strengthen communication with patients and families, focus on the management of acute postoperative pain. In order to reduce or avoid the occurrence of kinesiophobia and enable patients to benefit from early ambulation.

Autophagy is a cellular self-degradation process essential for maintaining metabolic functions in cells and organisms.Dysfunc-tional autophagy has been linked to various diseases,including cancer.The m6A modification,a major RNA modification in eukaryotes,plays a crucial role in regulating autophagy in tumor cells by regulating the expression of autophagy-associated genes(ATGs)or interfering with autophagy-related signaling pathways.Aberrant m6A modification can lead to dysregulated autophagy and impact tumor progression.However,the specific role of m6A in regulating tumor autophagy remains to be explored.Therefore,in this review,we discuss the role of m6A modification in tumor cell autophagy and examine its relationship with tumor progression and drug resistance,aiming to provide a the-oretical foundation for developing new therapeutic strategies.
