Накратко на български

Протеинът HHAT и неговото блокиране се изследват като начин за спиране на растежа на рака, например при агресивния рак на панкреаса. Това е важно, защото съществуващите лекарства не блокират напълно сигналите в клетките, които поддържат развитието на болестта.

Hhat inhibition as a novel approach for selective cancer treatment

The Hedgehog (Hh) pathway is a conserved cell-cell signalling pathway that is normally involved in the development of tissue, but is associated with cancer during maturity. There is strong evidence that Hh signalling plays an important role in pancreatic ductal adenocarcinoma (PDAC), a very deadly (5-year survival rate is 5%) form of cancer, as well as being involved in over 25% of cancer deaths. however, the Hh pathway is highly complex and includes several poorly understood branches. Nevertheless, completely removing Hh signalling has been shown to effectively inhibit PDAC growth. Approved Hh inhibitors Vismodegib and Sonidegib exist, but are not effective against PDAC because they do not completely inhibit Hh signalling. We propose developing alternative Hh targeting drugs that are capable of completely inhibiting Hh signalling, thus providing the tool compounds to start developing a drug against this deadly disease, and cancer more generally. Our approach is based on targeting the protein Hedgehog acyltransferase (HHAT), a critical protein in the Hh pathway. The overall objective of the project is to generate compounds that have the right potency and physicochemical properties to target HHAT in cells and animal models. This objective has been achieved, as we have generated a molecule that has high potency against HHAT, good stability, as well as being well tolerated in mice.

Цел на проекта

Being the first or second most common cause of premature death in over 100 countries, cancer imposes a major burden on modern societies worldwide. Inhibition of the Hedgehog pathway has had success, both in vitro and in the clinic, but resistance is a commonly encountered problem, making alternative Hedgehog modulators in high demand. Hhat is a membrane associated O-acyl transferase (MBOAT) whose only known function is the palmitoylation of Hedgehog, a posttranslational modification crucial for Hedgehog signalling. Targeting Hhat thus represents a uniquely specific way to target the hedgehog pathway that could be less prone to gaining resistance, but research in this area is hampered by a lack of good tool compounds. Here I propose to use cutting edge chemical biology tools to develop selective high potency Hhat inhibitors with thoroughly validated cellular activity. Such inhibitors are crucially needed to validate Hhat as a target in cancer therapy and the methodologies developed could be transferred to target other clinically relevant MBOATs in for example the Wnt pathway.
