Loss of Insulin Receptor Substrates 1 and 2 Suppresses Kras-Driven Non-Small Cell Lung Cancer
(2017-07-06)
Lung cancer remains the leading cause of cancer death worldwide, with non-small cell lung cancer (NSCLC) being the majority of diagnosed cases of lung cancer. Mutant KRAS is found in about 25% of all NSCLC and has proved ...
The Wnt5a-Ror Signaling Pathway in the Morphogenesis of the Embryo
(2015-07-13)
Embryonic development is orchestrated by relatively few conserved core developmental signaling pathways that are used reiteratively to grow, specify and shape all tissues in the body into their final functional forms. The ...
Molecular Determinants and Transcriptional Regulators in Triple Negative Breast Cancer
(2015-08-07)
Breast cancer is a highly heterogeneous disease with differences in histopathological and biological characteristics, variable prognoses, and response to therapy. Clinically, breast
tumors are classified based on the ...
Resistance to Targeted Therapy in Sonic Hedgehog Subgroup Medulloblastoma: Mechanisms and Treatment Strategies
(2016-05-17)
Aberrant activation of the Sonic Hedgehog (Shh) signaling network is implicated in many human cancers, including the most common cancer, basal cell carcinoma (BCC) and the brain tumor medulloblastoma. Suppressing Shh ...
Molecular Mechanism of Secretory Protein Translocation by the SecA ATPase
(2015-05-06)
In bacteria, most secretory proteins are translocated across the plasma membrane by the interplay of the SecA ATPase and the SecY channel. How SecA moves a broad range of polypeptide substrates is only poorly understood. ...
Cell Shape and Treatment Duration: How They Influence a Cancer Cell's Response to TNF
(2016-05-17)
The purpose of my research was to investigate the sources of heterogeneity in cellular decisions that are based on both external and internal cues. I used the signaling network induced by tumor necrosis factor (TNF) as a ...
Isogenic Human Pluripotent Stem Cell Models of Cardiovascular Disease-Associated Genetic Variation
(2016-03-30)
A complex interplay of genetic and environmental factors underlies the development of common human diseases such as cardiovascular disease. Despite widespread use of existing medications, coronary heart disease (CHD), ...
A Novel Program of Ubiquitination Remodels the Erythroid Proteome During Terminal Differentiation
(2016-05-17)
The ubiquitin-proteasome system was initially discovered in reticulocytes, which undergo massive and rapid proteome remodeling. During terminal differentiation, hundreds of generic constituents of the cell undergo programmed ...
Nucleotide Modifications of RNA Suppress RIG-I Antiviral Signaling by Unique Mechanisms
(2016-05-02)
In order to counter pathogen infection while preventing autoimmune responses, the human innate immune system must be precisely regulated to distinguish “self” from “non-self”. Pattern recognition receptors detect “non-self” ...
Mechanisms of Resistance to MAPK Pathway Inhibition in RAS-Mutant Cancers
(2016-05-03)
The RAS family of genes are among the most frequently mutated genes in human cancers, including nearly all pancreatic cancers, ~40% of colorectal cancers, and ~30% of lung cancers. Although most RAS-mutant cancers depend ...
