Epigenetic Inheritance and Its Role in Evolutionary Biology: Re-Evaluation and New Perspectives

open access: yesBiology, 2016
Epigenetics increasingly occupies a pivotal position in our understanding of inheritance, natural selection and, perhaps, even evolution. A survey of the PubMed database, however, reveals that the great majority (>93%) of epigenetic papers have an intra-,

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Transcriptional effects of a positive feedback circuit in Drosophila melanogaster

open access: yesBMC Genomics, 2017
Background Synthetic systems that use positive feedback have been developed to control human disease vectors and crop pests. The tTAV system, which has been deployed in several insect species, relies on a positive feedback circuit that can be inhibited ...

Acceptance of Evolution Increases with Student Academic Level: A Comparison Between a Secular and a Religious College [PDF]

open access: yes, 2009
Acceptance of evolution among the general public, high schools, teachers, and scientists has been documented in the USA; little is known about college students’ views on evolution; this population is relevant since it transits from a high-school/parent ...

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Deciphering genetic adaptations of Old World camels through comparative genomic analyses across all camelid species

open access: yesiScience
Summary: Old World camels exhibit many unique traits for adaptations to desert environments, distinct from New World camels within the same family. Here, we conducted a comparative genomic analysis of three Old World camel species relative to four New ...

Group size influences maternal provisioning and compensatory larval growth in honeybees

open access: yesiScience, 2023
Summary: Environmental variation selects for the adaptive plasticity of maternal provisioning. Even though developing honeybees find themselves in a protected colony environment, their reproductively specialized queens actively adjust their maternal ...

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

A family of crown-of-thorns starfish spine-secreted proteins modify adult conspecific behavior

open access: yesiScience
Summary: With growing interest in utilizing semiochemicals to control pest species, recent investigations have begun to consider semiochemicals to control outbreaks of crown-of-thorns starfish (CoTS; Acanthaster cf.

The PWWP domain and the evolution of unique DNA methylation toolkits in Hymenoptera

open access: yesiScience, 2023
Summary: DNMT3 in Hymenoptera has a unique duplication of the essential PWWP domain. Using GST-tagged PWWP fusion proteins and histone arrays we show that these domains have gained new properties and represent the first case of PWWP domains binding to ...
