Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

Molecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

Fitness Estimation for Genetic Evolution of Bacterial Populations [PDF]

arXiv, 2018
In this paper we develop and test algorithmic techniques to estimate genotypes fitnesses by analysis of observed daily frequency data monitoring the long-term evolution of bacterial populations. In particular, we develop a non-linear least squares approach to estimate selective advantages of emerging new mutant strains in locked-box stochastic models ...

Detecting homologous recombination deficiency for breast cancer through integrative analysis of genomic data

Molecular Oncology, EarlyView.
This study develops a semi‐supervised classifier integrating multi‐genomic data (1404 training/5893 validation samples) to improve homologous recombination deficiency (HRD) detection in breast cancer. Our method demonstrates prognostic value and predicts chemotherapy/PARP inhibitor sensitivity in HRD+ tumours.

Alkane biosynthesis gene expression and its increased production in recombinant cyanobacteria

FEBS Open Bio, EarlyView.
The transcription and mRNA structures of the alkane biosynthesis genes ado/aar were analysed in the representative cyanobacteria PCC 6803 and SK1‐2‐1, which produce C17H36 and C15H32, respectively. PCC 6803 transconjugants carrying these genes showed a 1.8‐ to 2.3‐fold increase in C17H36 production.

Downregulation of O‐GlcNAcylation enhances etoposide‐induced p53‐mediated apoptosis in HepG2 human liver cancer cells

FEBS Open Bio, EarlyView.
Etoposide, a topoisomerase II inhibitor, reduces O‐GlcNAcylation in HepG2 liver cancer cells. Further inhibition of O‐GlcNAc transferase by OSMI‐1 enhanced etoposide‐induced apoptosis, lowering the IC50 for viability and increasing the EC50 for cytotoxicity.

Whole genome sequencing for mutation discovery in a single case of lysosomal storage disease (MPS type 1) in the dog. [PDF]

, 2020
Mucopolysaccharidosis (MPS) is a metabolic storage disorder caused by the deficiency of any lysosomal enzyme required for the breakdown of glycosaminoglycans.

Improving TSP Solutions Using GA with a New Hybrid Mutation Based on Knowledge and Randomness [PDF]

arXiv, 2018
Genetic algorithm (GA) is an efficient tool for solving optimization problems by evolving solutions, as it mimics the Darwinian theory of natural evolution. The mutation operator is one of the key success factors in GA, as it is considered the exploration operator of GA.
