Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Population genetics of fungal diseases of plants

open access: yesParasite, 2008
Although parasitism is one of the most common lifestyles among eukaryotes, population genetics on parasites lag far behind those on free-living organisms.

Mitonuclear Mismatch is Associated With Increased Male Frequency, Outcrossing, and Male Sperm Size in Experimentally-Evolved C. elegans

open access: yesFrontiers in Genetics, 2022
We provide a partial test of the mitonuclear sex hypothesis with the first controlled study of how male frequencies and rates of outcrossing evolve in response to mitonuclear mismatch by allowing replicate lineages of C.

Pollination ecology and breeding system of two Calceolaria species in Chile [PDF]

open access: yes, 2014
Indexación: Web of Science; Scielo.Many angiosperms are exclusively dependent on pollinators for its reproduction (Matallana et al.2010; Arroyo et al. 2006).

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Multiple independent origins of auto-pollination in tropical orchids (Bulbophyllum) in light of the hypothesis of selfing as an evolutionary dead end [PDF]

open access: yes, 2015
Background: The transition from outcrossing to selfing has long been portrayed as an ‘evolutionary dead end because, first, reversals are unlikely and, second, selfing lineages suffer from higher rates of extinction owing to a reduced potential for ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Partial Selfing Can Reduce Genetic Loads While Maintaining Diversity During Experimental Evolution

open access: yesG3: Genes, Genomes, Genetics, 2019
Partial selfing, whereby self- and cross- fertilization occur in populations at intermediate frequencies, is generally thought to be evolutionarily unstable. Yet, it is found in natural populations.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

How does selfing affect the dynamics of selfish transposable elements?

open access: yesMobile DNA, 2012
Background Many theoretical models predicting the dynamics of transposable elements (TEs) in genomes, populations, and species have already been proposed.
