Stem cells are of great interest to the scientific community due to their potential role in
regenerative and rejuvenative medicine. However, their role in the aging process and …

Background: Species of crocodiles and cockroaches can withstand high radiation, reside in
unsanitary conditions, thrive on germ-infested feed, and are exposed to heavy metals, yet …

Tucked inside our cells, we animals (and plants, and fungi) carry mitochondria, minuscule
descendants of bacteria that invaded our common ancestor 2 billion years ago. This …

Cancer is a threat to multicellular organisms, yet the molecular evolution of pathways that
prevent the accumulation of genetic damage has been largely unexplored. The p53 network …

In 1973, two ornithologists and a bee biologist were awarded the Nobel Prize in Physiology
or Medicine. The decision to award a trio of animal behaviorists with this prize served not …

Dissecting the basis of naturally occurring trait variation is one of the central goals of modern
genetics. For eukaryotes, classic methods for this purpose rely on screens of recombinants …

The incidence of developing cancer should increase with the body mass, yet is not the case,
a conundrum referred to as Peto's paradox. Elephants have a lower incidence of cancer …

The hatcing enzyme gene (HE) encodes a protease that is indispensable for the hatching
process and is conserved during vertebrate evolution. During teleostean evolution, it is …

Aim: The objective of study I was to delineate and quantify sex differences in cancer risk and
survival together with assessing the potential gain achieved by eliminating the excess …

The caspase family of cysteine proteases consists of evolutionarily ancient regulators of the
programmed cell death (PCD) cascade known as apoptosis. Indeed, homologous caspase …
