Phytosphingosine is a long chain sphingoid base that occurs broadly in yeast, plants and animals including mammals. In yeast it is involved in mediating the heat stress response, perhaps through activation of the AGC-type protein kinases, Pkh1, Pkh2, Ypk1, Ypk2, and Sch9. It is proapoptotic in human cancer cell lines. PHS induces ΔΨm and release of cytochrome c from mitochondria either directly or through activation of p38 MAPK pathway. This leads to activation of caspase 9 followed by activation of caspase 3 and programmed cell death.
Osteosarcoma is a malignant bone sarcoma characterized by extensive genomic disruption and a propensity for metastatic spread. Osteoid production suggests a close relationship with normal osteoblasts, and the latter are the presumptive cell of origin of this disease. The HACE1

4%-9% of prostate cancers harbor homozygous deletions of the androgen-induced tumor suppressor gene, promyelocytic leukemia zinc finger (PLZF, ZBTB16). PLZF loss induces an in vitro phenotype of castration resistance and enzalutamide resistance. The association of low expression of PLZF and
