Our lab is interested in the area of epithelial cell biology and homeostasis in mammals. A single layer of epithelial cells lining tubules are found in several organs and serve protective and active functions. Thus, the differentiated epithelial cells are known to mediate a number of functions, including transmembrane transport, filtration and secretion in and out of the lumen. An interesting feature of epithelial cells is that they are able to de-differentiate and enter the cell cycle which is important for the maintenance of the lining, or proliferate after an injury to replenish for the lost cells and aid in organ regeneration (kidney tubular epithelia). Epithelial cell progenitors and stem cells such as those found in the bottom of colon crypts, divide to provide continuous renewal of differentiated columnar epithelial lining. The rates of epithelial cells turnover varies and depends on their specific function in a given organ. The regulation of the cell cycle is crucial for the homeostasis and regeneration of epithelia in vivo.
Accurate replication, segregation, and orientation of chromatin ensure genetic integrity and represent most important events during the epithelial cell division. Errors may result in either insufficient regeneration (degenerative pathology) or excessive uncontrolled proliferation (cancer). We are specifically interested in factors that sense and directly link chromatin integrity with the cell division, which is an exciting area of epithelial cell biology and is highly relevant to human diseases.
We use in vitro cell culture models, transgenic mice models, and human specimens to discover and validate factors that interact with chromatin and control cell cycle progression.
Project 1. Previously we and others identified the PHD zinc finger family JADE1/2/3 proteins as members of at least two HAT complexes (HBO1 and TIP60). We reported that the function of JADE1 is to target a HAT to chromatin via JADE1 PHD zinc fingers and enable acetylation of bulk histone H4. Acetylation and de-acetylation of specific lysine residues within the N-terminus of histone H4 is thought to be one of the key events required for chromatin replication and homeostasis during the cell cycle. In addition, control of chromatin modification is required for proper segregation in mitosis and cytokinesis. Recently we discovered unexpected role of JADE1, which defined JADE1 as novel cytokinesis checkpoint factor controlling the cell cycle progression. We are examining JADE1 pathway in epithelial cell proliferation. Project 1 is to identify the specific role in chromatin and cell division, mechanisms and molecular partners of JADE proteins.
For in vivo studies we choose kidney tubular and colon lining epithelia. These models are well characterized and are most suitable for the validation and translation of our molecular mechanistic findings. We use several models of acute and chronic kidney injury (AKI and CKI) and regeneration in mice which closely resembles human AKI and CKI – conditions known to associate with chronic and end stage kidney disease. We analyze colons of humans and mice which are ideal models to investigate molecular events during epithelial proliferation, differentiation, and apoptosis. We use transgenic mice models to determine the in vivo outcomes of gene depletion or overexpression.
Project 2. Kidney tubular injury and regeneration. This project examines biological role of the JADE1-HBO1 complex in kidney epithelial cell cycle. We used mice model of acute kidney injury after ischemia-reperfusion and recently reported the activation of JADE1-HBO1 complex during tubular cells regeneration. By using complementary in vitro and in vivo transgenic mice models, we are dissecting mechanisms by which HBO1-JADE1 participate in tissue regeneration. Our long term goal is to find out how these complexes regulate cell cycle in regenerating normal tissues, as well as in diseases with abnormal cell proliferation, including cancer.
Project 3. Cell cycle control and colon cancer. Several HAT complexes have been linked to diseases, including cancers. Moreover, PHD zinc fingers of known HATs and other proteins such as p300, MOZ, MORF, AIRE, INGs are targets of mutations in several diseases. JADE1 and HBO1 may play a role in pathogenesis of colon adenocarcinomas.
