Objective As colorectal cancer (CRC) remains one of the leading causes of cancer-related deaths, understanding novel therapeutic mechanisms is crucial. This research focuses on the role of extracellular vesicles (EVs) from bone marrow stromal cells (BMSCs) in delivering miR-766-3p to CRC cells, targeting the MYC/CDK2 signaling axis. Methods Differentially expressed genes between BMSCs-EVs and CRC were identified using the Gene Expression Omnibus database. miR-766-3p target genes were predicted via TargetScan and RNAInter, with protein interactions analyzed using the STRING database. The analysis included RT-qPCR and Western blot on samples from 52 CRC patients. Characterization of BMSCs-EVs was followed by their functional assessment on CRC cell lines and the normal colon cell line CCD-18CO, evaluating cellular uptake, proliferation, migration, invasion, and apoptosis. Results miR-766-3p was confirmed in BMSCs-EVs and found underexpressed in CRC. BMSCs-EVs transported miR-766-3p to CRC cells, inhibiting their proliferation, migration, and invasion while promoting apoptosis. miR-766-3p targeted MYC, leading to decreased CDK2 transcription. Overexpression of MYC in HCT-116 cells counteracted these effects. In vivo studies showed that BMSCs-EVs carrying miR-766-3p hindered tumor growth. Conclusion The study demonstrates the efficacy of BMSCs-EVs in delivering miR-766-3p to CRC cells, leading to the suppression of the MYC/CDK2 signaling pathway and hindering cancer progression.

Rapid changes in the health care environment have challenged educators to find more efficient methods of developing nurses. These demands are leading to the use of collaborative approaches to education. Nurse educators have also found that they have to rely on preceptors for orientation of new employees. The Texas Medical Center Collaborative Preceptor Program was developed in 1989 to prepare nursing preceptors for all nine participating institutions. The goals of the program were to increase efficient use of instructor time, standardize preceptor preparation in the Texas Medical Center, and offer more programs and prepare more nurses per year than each individual institution could do alone. There were many unexpected benefits as well, and future plans for collaboration are already being formulated.
