The evolutionarily conserved Wnt signal transduction pathway directs cell proliferation and differentiation during animal development and tissue homeostasis. Despite the fact that deregulation of Wnt signaling underlies numerous developmental disorders and cancers, including nearly all colorectal cancers, many of these mechanisms remain poorly understood. The long-term goal of research in the Ahmed Lab is to elucidate the mechanisms that activate Wnt signaling during animal development using a Drosophila model and to use this knowledge to identify control points in the pathway susceptible to therapeutic targeting in Wnt-driven diseases.

Work in my laboratory is focused on defining the pathway of events necessary for chromosomes to "do the right thing"" during meiosis and understanding the molecular events that cause reduced fidelity of meiotic chromosome segregation as oocytes age.

My laboratory's research examines the interaction between bacterial and viral pathogens in the respiratory tract, particularly in the setting of chronic lung diseases, like Cystic Fibrosis (CF). Current studies in the lab are focused on elucidating molecular mechanisms that govern the innate immune induction of biofilm growth in the lung. Translating the laboratory's bench studies to the bedside, our team collaborates with physicians in Otolaryngology and Pulmonary Medicine to examine viral-bacterial interactions in the upper and lower respiratory tracts of patients with chronic lung disease. We use a combination of live-cell imaging, microbiological, cell biological and cutting-edge genomics approaches with the long-term goal of identifying new therapeutic targets to disrupt and/or prevent the chronic Pseudomonas aeruginosa biofilm infections that are so devastating to people with CF.

  • TAcyl-coenzyme A: cholesterol acyltransferase (ACAT) is a membrane protein located in the endoplasmic reticulum. It catalyzes the formation of cholesteryl esters from cholesterol and long-chain fatty acyl-coenzyme A. Cholesteryl ester is the storage form of cholesterol. The first gene encoding the enzyme ACAT1 was identified in our laboratory. We have also purified this protein to homogeneity and characterized it biochemically. In many neurodegenerative diseases, the cholesterol-rich microdomains in the membranes of various cell types are disrupted. We have shown that in mouse models for Alzheimer's disease and for Niemann Pick type C disease, inactivating ACAT1 can divert the cholesterol storage pool, such that the "mobilized cholesterol" can repair the disrupted cholesterol-rich microdomains. Future investigations are directed to develop novel ACAT inhibitors to ameliorate Alzheimer's disease, Niemann-Pick type C disease, and atherosclerosis. We will also use biochemical and biophysical approaches to identify the active sites and regulatory sites in ACAT1 and to investigate the mechanistic consequence of inhibiting ACAT in macrophages, neurons, microglia, and astrocytes.

Esteban A. Orellana, Ph.D.

Assistant Professor, Molecular and Systems Biology

Office:  Remsen 725A


Esteban investigates whether changes in the chemical modification (also known as the epitranscriptome) of RNA molecules play a role in the development of human cancers. In all cells, RNAs perform a variety of functions, including synthesizing proteins. While messenger RNAs (mRNAs) provide the instructions for producing a protein, transfer RNAs (tRNAs) "read" the information in that message and supply the necessary amino acid building blocks. To function properly, these transfer RNAs must fold into the correct three-dimensional shape, a process that requires the RNA to be chemically modified. Owing to their high cellular abundance and stability, tRNAs have been commonly considered to be housekeeping molecules. However, it is becoming increasingly clear that tRNAs are highly regulated, and that even small changes in their abundance or their nucleotide modification levels can have profound effects, leading to aberrant translation, changes in protein expression, and disease states. The tRNA epitranscriptome and the functional tRNA pool have emerged as important regulatory layers in the translation of the human genome. However, our current understanding of the functional tRNA pool is limited. Therefore, the focus of the Orellana Lab is to study the causes and effects of tRNA dysregulation in human disease and to use this knowledge to develop tRNA-based therapeutics and diagnosis.

The bacteria resident in the human gastrointestinal tract (the gut microbiota) potently influence diverse aspects of human health, including immunity. However, the forces that govern the composition of the gut microbiota are poorly understood. Our work focuses on a mechanistic, ecological, and evolutionary understanding of how interbacterial interactions between members of the dominant Gram-negative bacteria in the gut, the Bacteroidales, modulate the composition of the microbiota. The Bacteroidales utilize a contact-dependent toxin-delivery system known as the type VI secretion system (T6SS) to kill neighboring cells. We study the impact of this pathway on the microbiota and how bacteria adapt to defend against T6SS-mediated antagonism, using a combination of bacterial genetics, biochemistry, metagenomics, and germ-free mouse models. We are also interested in understanding why Bacteroidales abundance is depleted in individuals with cystic fibrosis, with the goal of improving health through restoration of these bacteria.
