WebApoptosis is a normal developmental process in C. elegans. They found several genes involved in apoptosis, including ced−9 and ced−3. The ced−3 gene was found to promote cell death, and ced−9 to inhibit it. The ced−9 gene serves as a regulator that prevents apoptosis in the absence of a signal promoting apoptosis. WebB7-H3 belongs to the B7 family of immune checkpoint proteins, which are important regulators of the adaptive immune response and emerging key players in human cancer.
