Thermodynamics of DNA packaging inside a viral capsid: the role of DNA intrinsic thickness

, 2003
We characterize the equilibrium thermodynamics of a thick polymer confined in a spherical region of space. This is used to gain insight into the DNA packaging process. The experimental reference system for the present study is the recent characterization

Overexpression of CDT1 inhibits cell cycle progression at S phase by interacting with the mini‐chromosome maintenance complex and causes DNA damage

FEBS Open Bio, EarlyView.
CDT1 is an essential protein for DNA replication licensing that loads the MCM complex, the eukaryotic replicative DNA helicase, onto replication origins. Overexpression of CDT1 induces cell cycle arrest at the S phase. Here we showed CDT1 inhibits the progression of replication forks by interacting with the MCM complex, leading to the stalling and ...

Cloning, expression, purification, and structural modeling of the Chandipura virus matrix protein

FEBS Open Bio, EarlyView.
This research protocol offers a guide for the cloning, expression, and purification of the Chandipura virus matrix protein using E. coli. It also includes a step‐by‐step procedure for cloning, expressing, and conducting fluorescence imaging of GFP‐fused Chandipura virus matrix protein in mammalian cell lines.

Homologous expression and purification of human HAX‐1 for structural studies

FEBS Open Bio, EarlyView.
This research protocol provides detailed instructions for cloning, expressing, and purifying large quantities of the intrinsically disordered human HAX‐1 protein, N‐terminally fused to a cleavable superfolder GFP, from mammalian cells. HAX‐1 is predicted to undergo posttranslational modifications and to interact with membranes, various cellular ...

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

A Liquid Crystal Model of Viral DNA Encapsidation

, 2017
A liquid crystal continuum modeling framework for icosahedra bacteriophage viruses is developed and tested. The main assumptions of the model are the chromonic columnar hexagonal structure of confined DNA, the high resistance to bending and the phase ...

HPV oncogenes expressed from only one of multiple integrated HPV DNA copies drive clonal cell expansion in cervical cancer

mBio
The integration of HPV DNA into human chromosomes plays a pivotal role in the onset of papillomavirus-related cancers. HPV DNA integration often occurs by linearizing the viral DNA in the E1/E2 region, resulting in the loss of a critical viral early ...

Identification of a Proliferation Gene Cluster Associated with HPV E6/E7 Expression Level and Viral DNA Load in Invasive Cervical Carcinoma

, 2005
Specific HPV DNA sequences are associated with more than 90% of invasive carcinomas of the uterine cervix. Viral E6 and E7 oncogenes are key mediators in cell transformation by disrupting TP53 and RB pathways. To investigate molecular mechanisms involved
