Transporting small molecules across cell membranes is an essential process in cell physiology. Many structurally diverse, secondary active transporters harness transmembrane electrochemical gradients of ions to power the uptake or efflux of nutrients, signalling molecules, drugs and other ions across cell membranes. Transporters reside in lipid bilayers on the interface between two aqueous compartments, where they are energized and regulated by symported, antiported and allosteric ions ...

Divergence of cis-regulatory elements drives species-specific traits1, but how this manifests in the evolution of the neocortex at the molecular and cellular level remains unclear. Here we investigated the gene regulatory programs in the primary motor cortex of human, macaque, marmoset and mouse using single-cell multiomics assays, generating gene expression, chromatin accessibility, DNA methylome and chromosomal conformation profiles from a total of over 200,000 cells. From these data, we show ...

In diploid organisms, biallelic gene expression enables the production of adequate levels of mRNA1,2. This is essential for haploinsufficient genes, which require biallelic expression for optimal function to prevent the onset of developmental disorders1,3. Whether and how a biallelic or monoallelic state is determined in a cell-type-specific manner at individual loci remains unclear. MSL2 is known for dosage compensation of the male X chromosome in flies. Here we identify a role of MSL2 in regul...

The specific loss of midbrain dopamine neurons (mDANs) causes major motor dysfunction in Parkinson’s disease, which makes cell replacement a promising therapeutic approach1–4. However, poor survival of grafted mDANs remains an obstacle to successful clinical outcomes5–8. Here we show that the surgical procedure itself (referred to here as ‘needle trauma’) triggers a profound host response that is characterized by acute neuroinflammation, robust infiltration of perip...

Exosome Derived from Mesenchymal Stem Cells Alleviates Pathological Scars by Inhibiting the Proliferation, Migration and Protein Expression of Fibroblasts via Delivering miR-138-5p to Target SIRT1

Continued demand for brightening products drives R&D to search for approaches that optimize and further advance such cosmetics. In relation, this article reviews types of brightening agents, their mechanisms and corresponding action pathways.

In this study, we aimed to determine the relationship between Dicer and VEGF in HCC.
