The SNAP hypothesis: Chromosomal rearrangements could emerge from positive Selection during Niche Adaptation.

open access: yesPLoS Genetics, 2020
The relative linear order of most genes on bacterial chromosomes is not conserved over evolutionary timescales. One explanation is that selection is weak, allowing recombination to randomize gene order by genetic drift.

Tetraodon genome confirms Takifugu findings : most fish are ancient polyploids [PDF]

open access: yes, 2004
An evolutionary hypothesis suggested by studies of the genome of the tiger pufferfish Takifugu rubripes has now been confirmed by comparison with the genome of a close relative, the spotted green pufferfish Tetraodon nigroviridis.

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

open access: yesMolecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Methylation biomarkers can distinguish pleural mesothelioma from healthy pleura and other pleural pathologies

open access: yesMolecular Oncology, EarlyView.
We developed and validated a DNA methylation–based biomarker panel to distinguish pleural mesothelioma from other pleural conditions. Using the IMPRESS technology, we translated this panel into a clinically applicable assay. The resulting two classifier models demonstrated excellent performance, achieving high AUC values and strong diagnostic accuracy.

Mutations in the RB1 Gene in Argentine Retinoblastoma Patients and Uncommon Clinical Presentations [PDF]

open access: yes, 2015
Background: Retinoblastoma, the most common ocular cancer of childhood, is caused by inactivation of the RB1 tumor suppressor gene in the developing retina.

Diversification of Non-TIR Class NB-LRR Genes in Relation to Whole-Genome Duplication Events in Arabidopsis

open access: yesMolecular Plant-Microbe Interactions, 2005
Arabidopsis thaliana is believed to have experienced at least two and possibly three whole-genome duplication events in its evolutionary history. In order to investigate the evolutionary relationships between these duplication events and diversification ...

Analysis of flavonol regulator evolution in the Brassicaceae reveals MYB12, MYB111 and MYB21 duplications and MYB11 and MYB24 gene loss

open access: yesBMC Genomics, 2022
Background Flavonols are the largest subgroup of flavonoids, possessing multiple functions in plants including protection against ultraviolet radiation, antimicrobial activities, and flower pigmentation together with anthocyanins. They are of agronomical

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

open access: yesMolecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

Simulating Weak Attacks in a New Duplication–Divergence Model with Node Loss

open access: yesEntropy
A better understanding of protein–protein interaction (PPI) networks representing physical interactions between proteins could be beneficial for evolutionary insights as well as for practical applications such as drug development.

Unifying Parsimonious Tree Reconciliation

open access: yes, 2013
Evolution is a process that is influenced by various environmental factors, e.g. the interactions between different species, genes, and biogeographical properties.
