For transduction, intestinal organoids at a low passage number and 2d post-passaging were incubated with pretreated lentivirus (LRIG1^−/− or control) in culture medium containing polybrene. The suspension was centrifuged at 37 °C and 1000 ×g for 30 min and incubated at 37 °C for 4 h. After transduction, the organoids were cultured in medium supplemented with 1 μg/mL Puromycin for selection. Representative images of intestinal organoids cultured with supernatant.

Lenti-CRISPR viruses were generated via triple-plasmid transfection. Briefly, murine LRIG1 sgRNAs were designed with the Synthego CRISPR design tool. The oligos were synthesized, annealed, and cloned and inserted into the LentiCRISPR-LRIG1 vector, followed by Sanger sequencing verification. HEK293T cells were cotransfected with LentiCRISPR-LRIG1 or LentiCRISPR-Control along with the lentiviral second-generation helper plasmids psPAX2 and pCMV-VSV-G via PEI transfection reagent. The culture supernatants harvested at 48 h and 72 h posttransfection were filtered, concentrated with PEG8000 and finally frozen at −80 °C. For transduction, intestinal organoids at a low passage number and 2d $ost-passaging were incubated with pretreated lentivirus (LRIG1^−/− or control) in culture medium containing polybrene. The suspension was centrifuged at 37 °C and 1000 ×g for 30 min and incubated at 37 °C for 4 h. After transduction, the organoids were cultured in medium supplemented with 1 μg/mL Puromycin for selection.

For the stable expression of mCherry-PCBP2, SH-SY5Y and SH-SY5Y-APP cells were transduced with LV6-mCherry-PCBP2 and LV6-mCherry vectors. Forty-eight hours post-transduction, the cells were transferred to 10 cm dishes and supplemented with 2 μg/mL Puromycin. Clones expressing mCherry-PCBP2 were identified and selected using fluorescence microscopy.

To induce K‐TM silence in Jurkat T cells, single‐guide RNA was designed and inserted into pLX‐hPGK‐EGFP vector and constructed into lentivirus using the lentiviral packaging method described above. Transfection of sgRNA was performed with polyjet transfection reagent and cells were selected with Puromycin for 5 days and then used for cytotoxicity assay. As expected, Jurkat‐K‐TMKO T cells elicited stronger cytotoxicity against tumor cells compared to the control.

Cells were incubated with Puromycin (10 µg/mL) at 37 °C for 30 min, permeabilized and fixed for intracellular staining with AF488-conjugated anti-puromycin (1:100). Puromycin intake levels were detected by flow cytometry.
