A two-phase approach for detecting recombination in nucleotide sequences [PDF]

arXiv, 2007
Genetic recombination can produce heterogeneous phylogenetic histories within a set of homologous genes. Delineating recombination events is important in the study of molecular evolution, as inference of such events provides a clearer picture of the phylogenetic relationships among different gene sequences or genomes.

Envelope Ejection and the Transition to Homologous Expansion in Common-Envelope Events [PDF]

arXiv, 2023
We conduct a long-timescale ($5000\,$d) 3-D simulation of a common-envelope event with a $2\,M_{\odot}$ red giant and a $1\,M_{\odot}$ main sequence companion, using the moving-mesh hydrodynamic solver MANGA. Starting with an orbital radius of $52\,R_{\odot}$, our binary shrinks to an orbital radius of $5\,R_{\odot}$ in $200\,$d.

A Mixture Model and a Hidden Markov Model to Simultaneously Detect Recombination Breakpoints and Reconstruct Phylogenies

Evolutionary Bioinformatics, 2009
Homologous recombination is a pervasive biological process that affects sequences in all living organisms and viruses. In the presence of recombination, the evolutionary history of an alignment of homologous sequences cannot be properly depicted by a ...

Targeting KMT5C Suppresses Lung Cancer Progression and Enhances the Efficacy of Immunotherapy

Advanced Science, EarlyView.
This study reveals that KMT5C activates DNA damage repair to inhibit STING‐IRF3 pathway, downstream type I IFN signaling and CCL5 secretion, leading to the downregulation of CD8+ T cell infiltration and function in NSCLC, ultimately facilitating tumor progression.

Is modularity the reason why recombination is so ubiquitous? [PDF]

arXiv, 2012
Homologous recombination is an important operator in the evolution of biological organisms. However, there is still no clear, generally accepted understanding of why it exists and under what circumstances it is useful. In this paper we consider its utility in the context of an infinite population haploid model with selection and homologous ...

Developing Quorum Sensing‐Based Collaborative Dynamic Control System in Halomonas TD01

Advanced Science, EarlyView.
A standardized and streamlined inducer‐free quorum sensing (QS)‐based collaborative dynamic control pattern is developed for sufficient gene expression control in Halomonas TD by mixing two engineered cells, cells A and B. Proof‐of‐concept studies are designed to test the dynamic control performance in mixed cultures in fed‐batch conditions.

Molecular and cellular paradigms of multidrug resistance in cancer

Cancer Reports, Volume 5, Issue 12, December 2022., 2022
Abstract Background The acquisition of resistance to chemotherapy is a major hurdle in the successful application of cancer therapy. Several anticancer approaches, including chemotherapies, radiotherapy, surgery and targeted therapies are being employed for the treatment of cancer.

Targeting Replication Fork Processing Synergizes with PARP Inhibition to Potentiate Lethality in Homologous Recombination Proficient Ovarian Cancers

Advanced Science, EarlyView.
This study demonstrates that the resveratrol analogue, trans‐4,4′‐dihydroxystilbene (DHS), exhibits synergistic anti‐tumor activity with the PARP inhibitor talazoparib, inducing significant ovarian cancer cell death. The synergistic effect of this combination arises from the concurrent downregulation of homologous recombination factors and the ...

Mutation and recombination for hyperbolic 3-manifolds [PDF]

arXiv, 2011
We give a short topological proof for Rubermans Theorem about mutation and volume, using the Maskit combination theorem and the homology of the linear group.

A Novel Gene Synthesis Platform for Designing Functional Protein Polymers

Advanced Science, EarlyView.
A new gene synthesis method consisting of rolling‐circle amplification and seamless cloning facilitates the advanced design of protein polymers with repetitive sequences. This method is more cost‐effective and user‐friendly than conventional methods. Using this method, a library of polymers with different repeat units can be easily constructed.
