Differential roles of TGIF family genes in mammalian reproduction [PDF]
, 2011 BACKGROUND: TG-interacting factors (TGIFs) belong to a family of TALE-homeodomain proteins including TGIF1, TGIF2 and TGIFLX/Y in human. Both TGIF1 and TGIF2 act as transcription factors repressing TGF-β signalling.

Keratan Sulfate Is a Multifunctional Brain Glycosaminoglycan With Instructive Capabilities
Journal of Neurochemistry, Volume 169, Issue 8, August 2025.Keratan sulfate (KS) is a multifunctional glycosaminoglycan with fascinating instructional regulatory, tissue organizational, and stabilization properties in the brain. KS has essential properties that regulate neuron proliferation and differentiation with synaptic roles and perineuronal net activities in cognitive activity and memory that define brain

Global Ecology and Biogeography, Volume 34, Issue 7, July 2025.ABSTRACT Aim The late‐Quaternary extinctions, which affected primarily large mammals, are strongly connected to the migration of modern humans out of sub‐Saharan Africa and tropical Asia (the Palaeotropics), and human hunting remains one of the greatest threats to large mammals globally. Species traits are known to affect vulnerability to human impacts

The diversity of Class II transposable elements in mammalian genomes has arisen from ancestral phylogenetic splits during ancient waves of proliferation through the genome [PDF]
, 2012 DNA transposons make up three percent of the human genome, roughly the same percentage as genes. However, due to their inactivity, they are often ignored in favour of the more abundant, active, retroelements.

Disruption of FEM1C-W gene in zebra finch: evolutionary insights on avian ZW genes [PDF]
, 2009 Sex chromosome genes control sex determination and differentiation, but the mechanisms of sex determination in birds are unknown. In this study, we analyzed the gene FEM1C which is highly conserved from Caenorhabditis elegans to higher vertebrates and ...
