The mechanisms underlying cancer metastasis remain poorly understood. Here, we report that TFAM deficiency rapidly and stably induced spontaneous lung metastasis in mice with liver cancer. Interestingly, unexpected polymerization of nuclear actin was observed in TFAM-knockdown HCC cells when cytoske...

The chromatin of individual chromosomes is organized into chromosome territories (CTs) in the interphase nucleus. The spatial arrangement of CTs is non-random and evolutionarily conserved. The gene-dense and gene-poor CTs are positioned in the nuclear center and periphery, respectively. As candidate...

This study was aimed to identify pathways associated with loss-of-function of the DAP12/TREM2 receptor complex and thus gain insight into pathogenesis of PLOSL (polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy). Transcript profiles of PLOSL patients' DCs showed differenti...

Cancer cell motility and invasiveness are fundamental characteristics of the malignant phenotype and are regulated through diverse signaling networks involving kinases and transcription factors. In this study, we identify a nuclear hormone receptor (ERα)-protein kinase (ERK5)-cofilin (CFL1) network ...

KLF5 regulates actin remodeling to enhance the metastasis of nasopharyngeal carcinoma [RNA-seq]
Actin dependent astrocytic infiltration is a key step for axon defasciculation during remodeling
KLF5 regulates actin remodeling to enhance the metastasis of nasopharyngeal carcinoma [ChIP-seq]
Cellular differentiation is regulated through activation and repression of defined transcription factors. A hallmark of differentiation is a pronounced change in cell shape, which is determined by dynamics of the actin cytoskeleton. In de-differentiated fat (DFAT) cells and 3T3-L1 cells, we showed t...

The actin-related proteins (ARPs) comprise a conserved protein family. Arp4p is found in large multisubunits of the INO80 and SWR1 chromatin remodeling complexes and in the NuA4 histone acetyltransferase complex. Here we show that arp4 (arp4S23AD159A) temperature-sensitive cells are defective in G2/...
