We are interested to understand the role of the tumor microenvironment (TME) in cancer progression and different mediators involved in metastatic progression through the use of in vitro and in vivo model systems.

1. Commonly used chemotherapeutic drugs are known to induce inflammasome formation in the tumor microenvironment of certain cancers. Inflammasome components and pathways associated with inflammation and cancer in TME could be novel targets to tackle cancer progression. In TME, many factors are being secreted as a result of chemotherapeutic treatment, including IL-1β, IL-18 etc. through the activation of the inflammasome complex. Since these cytokines are pro-inflammatory in nature, they have also pro-tumorigenic effects. We examine the signalling pathways involved in cancer progression and therapy resistance in connection with inflammasome activation.
2. Secondly, chemotherapeutic drugs modulate epigenetic factors involved in tumorigenesis. It is established that tumor suppressor genes become switched off in a somatically heritable fashion through epigenetic changes, in addition to their classical mutations. Because of the dynamic nature and ready capacity for reversibility, epigenetic modifications are appealing therapeutic targets in cancer. Hence, we are exploring the epigenetic factors influencing inflammasome formation during tumor progression, metastasis, and in chemotherapy-resistant cancer.
