Abstract: The present disclosure describes how all-retinoic acid (ATRA) binds and inhibits Pin1 activity and induces degradation of the activated Pin1 monomer selectively in cancer cells. Identification of the binding mechanism of ATRA with Pin1 confirm ATRA binding specificity to Pin1 residues in the PPIase active site, thus demonstrating that drug-induced Pin1 ablation has potent anticancer activity, such as in acute promyelocytic leukemia (APL), by inducing PML-RARa degradation, as well as against other types of cancer and diseases that are associated with Pin1 overexpression, such as aggressive triple negative breast cancer, lupus, asthma, cocaine addiction, among others, due to their unique ability to simultaneously block numerous cancer-driving pathways, with relatively lower toxicity. The present disclosure also provides a rationale for developing sustained released ATRA-containing formulations.

Abstract: Biomarkers and driver mutations for diagnosis and prognosis of Pin 1-associated diseases are disclosed. In one embodiment, the methods for diagnosis of Pin 1-associated diseases may include detecting the level of Pin1 to stage abnormal cell growth, such as breast or prostate cancer. In another embodiment, the methods include evaluating the efficacy of a treatment of abnormal cell growth, such as cancer, by monitoring the levels of Pin1. In another embodiment, the methods include using driver mutations to determine the pharmacogenetics of abnormal cell growth, such as cancer. In the present disclosure, elevated active monomeric Pin1 levels may be detected by Pin1 biomarkers, which may include Pin1 Q33K or E100D driver mutations, Pin1 protein or transcript overexpression, dephosphorylation of Pin1 on Ser71, dephosphorylation of S16, phosphorylation of S65, phosphorylation of S138, deacetylation of Pin1 on K13 and deacetylation of K46, and/or desumoylation of Pin1 on K6 and desumolation of K63, among others.

Abstract: The invention features all-trans retinoic acid (ATRA)-related compounds capable of associating with Pin1 and methods of identifying the same. The invention also provides methods of treating a condition selected from the group consisting of a proliferative disorder, an autoimmune disease, and an addiction condition characterized by elevated Pin1 marker levels, Pin1 degradation, and/or reduced Pin1 Ser71 phosphorylation in a subject by administering a retinoic acid compound. Additionally, the invention features methods of treating proliferative disorders, autoimmune diseases, and addiction conditions (e.g., diseases, disorders, and conditions characterized by elevated Pin1 marker levels) by administering a retinoic acid compound in combination with another therapeutic compound. The invention also features a co-crystal including Pin1 and a retinoic acid compound.
