(Submitter supplied) Immune checkpoints are often expressed on tumor cells; it remains a prevailing need to identify the mechanisms underlying their regulation and therapeutic benefit. The immune checkpoint molecule B7-H3 is upregulated in many human tumors, including those with high mechanistic/mammalian target of rapamycin complex (mTORC1) activity. However, its role in tumor immunity and the impact of B7-H3-targeted therapy on the tumor immune microenvironment are largely uncharacterized. more...

(Submitter supplied) Analysis of mouse ovarian cancer cell lines HM-1 and ID8, and HM-1 tumors inoculated to B6C3F1 mice with B7-H3 (Cd276) knockout (KO) by CRISPR-Cas9. We identified B7-H3 expression is upregulated in IFN-γ–low, PD-L1–low non-immunoreactive tumors of high grade serous ovarian cancer. We explored the influence of B7-H3 on immune evasion outside of its direct regulatory function on target cells by generating B7-H3 knockout cell lines and tumors in syngeneic mouse models.

(Submitter supplied) Abstract. The use of large animal spontaneous models of solid cancers, such as dogs with osteosarcoma (OS), can help develop new cancer immunotherapy approaches, including chimeric antigen receptor (CAR) T cells. Therefore, the goal of the present study was to generate canine CAR T cells targeting the B7-H3 (CD276) co-stimulatory molecule overexpressed by several solid cancers, including OS and glioma in both humans and dogs, and to assess their ability to recognize B7-H3 expressed by canine OS cell lines or by canine tumors in xenograft models. more...

(Submitter supplied) We have employed mRNA microarray expression profiling as a discovery platform to identify genes with the potential to explain how small dose SAHA promoted the cell toxicity of B7-H3 CAR-T cells. B7-H3 CAR-T cells were treated by 0.5μM SAHA for 5 days, and with control samples.
