Identification of potential substrates of LNX1 in chicken cells.

Ubiquitination of proteins is involved in numerous life activities. In poultry, several ubiquitin ligases tightly control the innate immune response, imbalance of which may result in autoimmune diseases and seriously impair poultry growth, development, and productivity. LNX1, an E3 ubiquitin ligase, catalyzes the ubiquitination and subsequent degradation of specific substrate proteins.

Spop deficiency impairs adipogenesis and promotes thermogenic capacity in mice.

As the adaptor protein that determines substrate specificity of the Cul3-SPOP-Rbx1 E3 ligase complex, SPOP is involved in numerous biological processes. However, its physiological connections with adipogenesis and thermogenesis remain poorly understood. In the current study, we report that the conditional knockout of Spop in mice results in substantial changes in protein expression, including the upregulation of a critical factor associated with thermogenesis, UCP1.

Effects of grazing on the relationship between dominant shrubs and understory vegetation along sand dune stability gradient.

During the process of dune vegetation restoration, understanding how grazing disturbance affects the relationship between plant species is a critical issue in ecological studies.

We aimed to study how grazing and dune stabilization affects the relationship between Caragana microphylla and understory vegetation.

Temporal dynamic alterations of regional homogeneity in major depressive disorder: a study integrating machine learning.

Previous studies have found alterations in the local regional homogeneity of brain activity in individuals diagnosed with major depressive disorder. However, many studies have failed to consider that even during resting states, brain activity is dynamic and time-varying. The lack of investigation into the dynamic regional homogeneity has hindered the discovery of biomarkers for depression.

Characteristics, Relationships, and Anatomical Basis of Leaf Hydraulic Traits and Economic Traits in Temperate Desert Shrub Species.
