The visualization of nuclear architecture, which changes dynamically depending on the physiological and the pathological situation, remains an important challenge. Here we report that exposure of fluoresceinisothiocyanate-labeled polyethylenimine (FITC-PEI) to digitonin-permeabilized cervical cancer HeLa cells enable rapid detection of the

Nature communications, 5, 3832-3832 (2014-05-09)
Misfolded ER proteins are retrotranslocated into the cytosol for degradation via the ubiquitin-proteasome system. The human cytomegalovirus protein US11 exploits this ER-associated protein degradation (ERAD) pathway to downregulate HLA class I molecules in virus-infected cells, thereby evading elimination by cytotoxic

The Journal of general virology, 95(Pt 1), 71-79 (2013-10-12)
Japanese encephalitis virus (JEV) infection-induced encephalitis causes extensive death or long-term neurological damage, especially among children, in south and south-east Asia. Infection of mammalian cells has shown induction of an unfolded protein response (UPR), presumably leading to programmed cell death

Despite the frequent expression of N-terminally truncated ErbB2 (ΔNErbB2/p95HER2) in breast cancer and its association with Herceptin resistance and poor prognosis, it remains poorly understood how ΔNErbB2 affects chemotherapy-induced cell death. Previously it was shown that ΔNErbB2 upregulates acid extrusion

Nucleic acids research, 39(10), 4048-4062 (2011-01-27)
The centromere is a highly specialized chromosomal element that is essential for chromosome segregation during mitosis. Centromere integrity must therefore be properly preserved and is strictly dependent upon the establishment and maintenance of surrounding chromatin structure. Here we identify WDHD1
