Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

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 ...

Plastic cell morphology changes during dispersal

open access: yesiScience, 2021
Summary: Dispersal is the movement of organisms from one habitat to another that potentially results in gene flow. It is often plastic, allowing organisms to adjust dispersal movements depending on environmental conditions.

On the methodology of feeding ecology in fish [PDF]

open access: yes, 2016
Feeding ecology explains predator’s preference to some preys over others in their habitat and their competitions thereof. The subject, as a functional and applied biology, is highly neglected, and in case of fish, a uniform and consistent ...

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

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.

Evolutionary Biology Needs Wild Microbiomes

open access: yesFrontiers in Microbiology, 2017
The microbiome is a vital component to the evolution of a host and much of what we know about the microbiome derives from studies on humans and captive animals.

On the effect of inheritance of microbes in commensal microbiomes

open access: yesBMC Ecology and Evolution, 2022
Background Our current view of nature depicts a world where macroorganisms dwell in a landscape full of microbes. Some of these microbes not only transit but establish themselves in or on hosts.

Alternative telomere maintenance mechanism in Alligator sinensis provides insights into aging evolution

open access: yesiScience, 2023
Summary: Lifespan is a life-history trait that undergoes natural selection. Telomeres are hallmarks of aging, and shortening rate predicts species lifespan, making telomere maintenance mechanisms throughout different lifespans a worthy topic for study ...
