An expanded polyglutamine tract (>37 glutamines) in the N-terminal region of huntingtin (htt) causes htt to accumulate in the nucleus, leading to transcriptional dysregulation in Huntington disease (HD). In HD knock-in mice that express full-length mutant htt at the endogenous level, mutant htt preferentially accumulates in the nuclei of striatal neurons,(More)
Vimentin is an intermediate filament protein whose expression correlates with increased metastatic disease, reduced patient survival and poor prognosis across multiple tumor types. Despite these well-characterized correlations, the molecular role of vimentin in cancer cell motility remains undefined. To approach this, we used an unbiased phosphoproteomics(More)
There are nine inherited neurodegenerative disorders caused by polyglutamine (polyQ) expansion in various disease proteins. Although these polyglutamine proteins have different functions and are localized in different subcellular regions, all the polyQ diseases share a common pathological feature: the nuclear accumulation of polyQ disease proteins and the(More)
Triple negative breast cancer (TNBC) is a highly metastatic disease that currently lacks effective prevention and treatment strategies. The insulin-like growth factor 1 receptor (IGF1R) and focal adhesion kinase (FAK) signaling pathways function in numerous developmental processes, and alterations in both are linked with a number of common pathological(More)
