The replisome guides nucleosome assembly during DNA replicationSpringer Science and Business Media LLC - Tập 10 Số 1 - 2020
Wenshuo Zhang, Jianxun Feng, Qing Li
AbstractNucleosome assembly during DNA replication is tightly coupled to ongoing
DNA synthesis. This process, termed DNA replication-coupled (RC) nucleosome
assembly, is essential for chromatin replication and has a great impact on both
genome stability maintenance and epigenetic inheritance. This review discusses a
set of recent findings regarding the role of replisome components contributing

Cell type-specific function of TRAF2 and TRAF3 in regulating type I IFN inductionSpringer Science and Business Media LLC - Tập 9 - Trang 1-10 - 2019
Xiaoping Xie, Jin Jin, Lele Zhu, Zuliang Jie, Yanchuan Li, Baoyu Zhao, Xuhong Cheng, Pingwei Li, Shao-Cong Sun
TRAF3 is known as a central mediator of type I interferon (IFN) induction by
various pattern recognition receptors, but the in vivo function of TRAF3 in host
defense against viral infection is poorly defined due to the lack of a viable
mouse model. Here we show that mice carrying conditional deletion of TRAF3 in
myeloid cells or dendritic cells do not have a significant defect in host
defense agai... hiện toàn bộ
WRN loss accelerates abnormal adipocyte metabolism in Werner syndromeSpringer Science and Business Media LLC - Tập 14 - Trang 1-19 - 2024
Yuyao Tian, Sofie Lautrup, Patrick Wai Nok Law, Ngoc-Duy Dinh, Evandro Fei Fang, Wai-Yee Chan
Metabolic dysfunction is one of the main symptoms of Werner syndrome (WS);
however, the underlying mechanisms remain unclear. Here, we report that loss of
WRN accelerates adipogenesis at an early stage both in vitro (stem cells) and in
vivo (zebrafish). Moreover, WRN depletion causes a transient upregulation of
late-stage of adipocyte-specific genes at an early stage. In an in vivo study,
we gener... hiện toàn bộ
Identification of target genes for spermatogenic cell-specific KRAB transcription factor ZFP819 in a male germ cell lineSpringer Science and Business Media LLC - Tập 7 - Trang 1-15 - 2017
Sora Jin, Heejin Choi, Jun Tae Kwon, Jihye Kim, Juri Jeong, Jaehwan Kim, Seong Hyeon Hong, Chunghee Cho
Zfp819, a member of the Krüppel-associated box (KRAB) family, encodes a
spermatogenic cell-specific transcription factor. Zfp819-overexpression induces
apoptosis and inhibits proliferation in somatic cell lines. In the present
study, we examined the cellular effects of Zfp819 in a male germ cell line (GC-2
cells). Overexpression of Zfp819 demonstrated an increase in the number of
apoptotic cells, ... hiện toàn bộ
Metabolomic profiling of Burkholderia pseudomallei using UHPLC-ESI-Q-TOF-MS reveals specific biomarkers including 4-methyl-5-thiazoleethanol and unique thiamine degradation pathwaySpringer Science and Business Media LLC - Tập 5 - Trang 1-14 - 2015
Susanna K. P. Lau, Ching-Wan Lam, Shirly O. T. Curreem, Kim-Chung Lee, Wang-Ngai Chow, Candy C. Y. Lau, Siddharth Sridhar, Sally C. Y. Wong, Paolo Martelli, Suk-Wai Hui, Kwok-Yung Yuen, Patrick C. Y. Woo
Burkholderia pseudomallei is an emerging pathogen that causes melioidosis, a
serious and potentially fatal disease which requires prolonged antibiotics to
prevent relapse. However, diagnosis of melioidosis can be difficult, especially
in culture-negative cases. While metabolomics represents an uprising tool for
studying infectious diseases, there were no reports on its applications to B.

Molecular mechanism of double Holliday junction dissolutionSpringer Science and Business Media LLC - Tập 4 - Trang 1-5 - 2014
Paolo Swuec, Alessandro Costa
Processing of homologous recombination intermediates is tightly coordinated to
ensure that chromosomal integrity is maintained and tumorigenesis avoided.
Decatenation of double Holliday junctions, for example, is catalysed by two
enzymes that work in tight coordination and belong to the same ‘dissolvasome’
complex. Within the dissolvasome, the RecQ-like BLM helicase provides the
translocase functi... hiện toàn bộ
Proteomic analysis of mismatch repair-mediated alkylating agent-induced DNA damage responseSpringer Science and Business Media LLC - Tập 3 - Trang 1-14 - 2013
Xi Chen, Yong Zhao, Guo-Min Li, Lin Guo
Mediating DNA damage-induced apoptosis is an important genome-maintenance
function of the mismatch repair (MMR) system. Defects in MMR not only cause
carcinogenesis, but also render cancer cells highly resistant to
chemotherapeutics, including alkylating agents. To understand the mechanisms of
MMR-mediated apoptosis and MMR-deficiency-caused drug resistance, we analyze a
model alkylating agent (N-... hiện toàn bộ
