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

FEBS 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.

PPARgamma Deficiency Counteracts Thymic Senescence

Frontiers in Immunology, 2017
Thymic senescence contributes to increased incidence of infection, cancer and autoimmunity at senior ages. This process manifests as adipose involution. As with other adipose tissues, thymic adipose involution is also controlled by PPARgamma.

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

In Vitro and In Vivo Assessment of an Innovative Peeling System with Azelaic and Tranexamic Acids for Targeted Hyperpigmentation Reduction

Dermatology and Therapy
Introduction Melanin, derived from tyrosine, plays a pivotal role in skin pigmentation through melanogenesis. Disruptions in this process lead to hyperpigmentation, a condition affecting skin tone and quality of life.
