Small Molecule Regulator of ENTPD5, and ER Enzyme in the PTEN/AKT Pathway
PI3K signaling plays a crucial role in effecting alterations in a broad range of cellular functions in response to diverse extracellular stimuli (insulin, growth factors, integrins and GPCRs etc.). A key downstream effector of PI3K is the serine-threonine kinase Akt, which in response to PI3K …

The Endoplasmic Reticulum Udpase ENTPD5 Promotes Cancer Cell Growth and Survival in the PI3K/PTEN
… of protein folding and accumulation of unfolded proteins in the ER and finally lead to ER stress. How does cancer cell solve this problem of increased folding during rapid growth to avoid ER stress? We discovered that ENTPD5, an endoplasmic reticulum (ER) enzyme, is up-regulated in cell lines and …

Evaluation of Chronic RalGTPase Activation as a Core Specifier of Oncogenic Transformation
… tumorigenicity of cancers that are driven by oncogenes other than Ras. In order to begin to understand how the Ral pathway may be chronically engaged in diverse oncogenic backgrounds, we further examined the expression of RalGEFs in a variety of cells derived from different tissue origin. Our …

The Role of Protocadherin 7 in Lung Adenocarcinoma
Lung cancer is the leading cause of cancer-associated deaths worldwide. Despite recent advances in the development of targeted therapies for lung cancer, most patients develop resistance to these targeted therapies. Our lab has uncovered a key oncogenic role for Protocadherin 7 (PCDH7) in non-small …

Novel Functions of the Transcription Factor Aryl Hydrocarbon Receptor (AHR) and Its Tryptophan-Derived Ligands in Cancer Cells
… of cancer cells, focusing on the proto-oncogene MYC and the aryl hydrocarbon receptor (AHR). The role of MYC in regulating tryptophan (Trp) metabolism was investigated in colon and liver cancer cells using high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). Our …

Molecular Mechanisms Underlying Innate Immune Kinase TBK1-Driven Oncogenic Transformation
… immune response, re-exposure to glucose, or oncogene activation, TBK1 is recruited to the exocyst, where it activates AKT. In cells lacking TBK1, insulin activates AKT normally, but AKT activation by these exocyst-dependent mechanisms is impaired. Discovery and characterization of a …

Molecular Regulation of Direct Cardiac Reprogramming
A heart attack (also known as myocardial infarction, MI) happens when the flow of blood to the heart is blocked. A massive heart attack can kill billions of cardiomyocytes. The heart has limited regenerative potential because adult mammalian cardiomyocytes cannot proliferate, therefore lost …

Behavioral, Neurochemical, and Histological Characterization of Mice Deficient for Parkin, DJ-1, and Antioxidant Proteins
… We predicted that reducing levels of antioxidant proteins in parkin-/-DJ-1-/- mice would result in age-dependent nigral cell loss, striatal dopamine depletion or behavioral abnormalities. Characterization of these mice for behavioral abnormalities, neurotransmitter defects and neuropathology, …

Validation of AXL as a Therapeutic Target in Pancreatic Cancer
Pancreatic ductal adenocarcinoma (PDA), a leading cause of cancer-related death in the US, has a high metastatic rate that is associated with persistent immune suppression. AXL, a member of the TAM (TYRO3, AXL, MERTK) receptor tyrosine kinase family, has been identified as a critical factor that …

Molecular Players in Lupus: Leads from Proteomic Screens
Systemic Lupus Erythematosus is a multifactorial systemic autoimmune disorder marked by anti-nuclear antibodies (ANA), rashes and photosensitivity, joint inflammation, nephritis, and other clinical criteria. SLE develops through the breakdown of three major checkpoints: adaptive immune tolerance, …

Epithelial Tubular Fusion, Measuring Interconnection, and the Quest for Solving the Continuity Problem
The formation of functional epithelial tubules is a central feature of many organ systems. Although it has been well-studied how epithelial cells form tubules, it is not well understood how tubules and related epithelial micro-tissues such as spheroids and organoids interconnect with each other to …

Ubiquitination of EpoR and p85 in Ligand Induced EpoR Down-Regulation
… cytoplasmic tyrosines of the EpoR. Signaling proteins bind these phosphotyrosines through SH2 domains, leading to the survival and proliferation of erythroid progenitor cells and the differentiation of these progenitors into mature erythrocytes. Therefore, EpoR signaling is essential for red …

Identification and Characterization of a Selective Inhibitor of the PIM-1 Kinase
<p>The PIM-1 kinase is a serine/threonine kinase that has been implicated in the development of many human cancers, including leukemias, lymphomas, and prostate cancer. We have endeavored to identify and characterize a selective inhibitor of the PIM- 1 kinase. Such an inhibitor would have utility …

Investigating the Role of Complex I Loss in Thyroid Tumorigenesis
Changes in cellular metabolism are considered one of the hallmarks of cancer. In 1924, Otto Warburg initially posited that defects in cellular respiration drive tumorigenesis after observing that tumor cells often perform aerobic glycolysis in culture. Since then, multiple studies have demonstrated …

Oncogene-Induced Signaling Heterogeneity in Lung Cancer
… has identified 138 frequently occurring driver oncogenes and tumor suppressor genes in lung cancer. Currently, only 15 of these genes can be targeted therapeutically. Study of downstream signaling alterations of these oncogenes and tumor suppressor genes may identify novel therapeutic targets. …

Identification of Oncogenic KRAS-Associated Vulnerabilities in Non-Small Cell Lung Cancer
Activating mutations in KRAS are frequently involved in the pathogenesis of non-small cell lung cancer (NSCLC), the disease responsible for the most cancer-related deaths in the US. Despite intensive efforts to develop drugs that directly interfere with KRAS activity over the past decade, no …
