IFNγ regulates ferroptosis in KFs by inhibiting the expression of SPOCD1 through DNMT3A.

Keloid is benign skin tumor, and their curing is relatively difficult due to the unclear mechanism of formation. Inducing ferroptosis of keloid fibroblasts (KFs) may become a new method for treating keloid. Here, we discover interferon (IFN)γ could induce KFs ferroptosis through inhibiting SPOC domain-containing protein 1 (SPOCD1), serving as a mode of action for CD8T cell (CTL)-mediated keloid killing.

The direct growth of SWCNT arrays using high-activity metal catalysts is one of the promising methods to approach the mass production of dense SWCNT arrays. However, an inevitable obstacle lies in the post-purification of metal residual.

Monoallelic loss-of-function variants in GSK3B lead to autism and developmental delay.

De novo variants adjacent to the canonical splicing sites or in the well-defined splicing-related regions are more likely to impair splicing but remain under-investigated in autism spectrum disorder (ASD). By analyzing large, recent ASD genome sequencing cohorts, we find a significant burden of de novo potential splicing-disrupting variants (PSDVs) in 5048 probands compared to 4090 unaffected siblings. We identified 55 genes with recurrent de novo PSDVs that were highly intolerant to variation.

Evolution of catalyst design for controlled synthesis of chiral single-walled carbon nanotubes.

Single-walled carbon nanotubes (SWCNTs) possess superb properties originating from their unique chiral structures. However, accurately controlling the structure of SWCNTs remains challenging due to the structural similarities of their chiral structures, which hinders their widespread application in various fields, particularly in electronics. In recent years, much effort has been devoted to preparing single chiral SWCNTs by adopting three constructive strategies, including growth condition control for structurally unstable liquid catalysts, employing stable solid catalyst design, and pre-synthesis of carbon seeds with a well-defined shape.

Polychromatic full-polarization control in mid-infrared light.

Objects with different shapes, materials and temperatures can emit distinct polarizations and spectral information in mid-infrared band, which provides a unique signature in the transparent window for object identification. However, the crosstalk among various polarization and wavelength channels prevents from accurate mid-infrared detections at high signal-to-noise ratio. Here, we report full-polarization metasurfaces to break the inherent eigen-polarization constraint over the wavelengths in mid-infrared.
