Research on the Mechanism of Lphn1 Knockout in Inhibiting Colorectal Cancer

Decades ago, colorectal cancer was rarely diagnosed. Today, it is the fourth leading cause of cancer-related deaths worldwide, with nearly 90,000 fatalities each year. By analyzing single-cell data from tumor-bearing colorectal cancer model mice with Lphn1 knockout and wild-type Lphn1, we identified five key target genes for anticancer therapy: Ulbp1, Klrk1, Ccl6, Tlr4, Cd48, Prdm5, VSTM2A, RET, OAS2, Hdac11 and Ptchd4, along with their corresponding cell types. Additionally, we discovered tumor-inhibiting cell subpopulations, including Cd244a_T_cells_subcluster_1, Cd48_Cd244a_NK_cells_subcluster_2, and C3_Macrophages_subcluster_1, which are potential candidates for therapeutic intervention. We propose that cancer-associated fibroblasts (CAFs) serve as the primary antigen presenters for MHC class I, providing antigens to macrophages, NK cells, and T cells to combat colorectal cancer. These findings could open new avenues for the treatment of colorectal cancer and contribute to the development of personalized medicine.
