Atmospheric deposition of pollutants at three altitudes on Mount Emei, Sichuan Basin, southwestern China.

Comparing the atmospheric deposition chemistry between above and below the planetary boundary layer (PBL) may help understand the impacts from inter-regional air pollutant transport and local emissions to air pollutant deposition. In this study, we monitored ions, soluble and insoluble potentially toxic elements (PTEs), and dissolved organic nitrogen and carbon at the base (M-base: 551 m asl), middle (M-middle: 2400 m asl), and summit (M-summit: 3077 m asl) on Mount Emei. The annual volume-weighted mean (VWM) concentrations of all measured components were substantially higher at M-base than at M-summit, except for Na, Cl, and NO as Na and Cl at M-summit may be largely from ocean and NO to NO transformation may be faster at M-base.

Antibacterial and antifungal pyrazoles based on different construction strategies.

YTHDC1 as a tumor progression suppressor through modulating FSP1-dependent ferroptosis suppression in lung cancer.

Ferroptosis is a regulated cell death process initiated by iron-dependent phospholipid peroxidation and is mainly suppressed by GPX4-dependent and FSP1-dependent surveillance mechanisms. However, how the ferroptosis surveillance system is regulated during cancer development remains largely unknown. Here, we report that the YTHDC1-mediated mA epigenetic regulation of FSP1 alleviates the FSP1-dependent ferroptosis suppression that partially contributes to the tumor suppressive role of YTHDC1 in lung cancer progression.

Improving runoff quality in vertical greenery systems: Substrate type outweighed the effect of plant growth promoting microbes.

Due to limited urban green spaces and catchments, researchers are exploring the capacity of vertical greenery systems (VGSs) in stormwater management as complementary strategies. While the literature acknowledges the significant impacts of vegetated roof substrates on stormwater, comparing the stormwater management capacities of organic and non-organic substrates for VGSs remains largely unexplored. It is thus essential to gather empirical evidence to enhance the stormwater management capacity of VGSs.

A potassium-chloride co-transporter promotes tumor progression and castration resistance of prostate cancer through mA reader YTHDC1.

SLC12A5, a neuron-specific potassium-chloride co-transporter, has been reported to promote tumor progression, however, the underlying mechanism remains unclear. Here we report that SLC12A5 functions as an oncogene to promote tumor progression and castration resistance of prostate cancer through the N6-methyladenosine (mA) reader YTHDC1 and the transcription factor HOXB13. We have shown that the level of SLC12A5 was increased in prostate cancer, in comparison to its normal counterparts, and further elevated in castration-resistant prostate cancer (CRPC).

Plant growth-promoting microbes improve stormwater retention of a newly-built vertical greenery system.

Inactivation of SERCA2 Cys accelerates aortic aneurysms by suppressing PPARγ.

Background And Purpose: Inactivation of Cys (C674) in the sarcoplasmic/endoplasmic reticulum Ca ATPase 2 (SERCA2) causes intracellular Ca accumulation, which activates calcineurin-mediated nuclear factor of activated T-lymphocytes (NFAT)/NF-κB pathways, and results in the phenotypic modulation of smooth muscle cells (SMCs) to accelerate angiotensin II-induced aortic aneurysms. Our goal was to investigate the mechanism involved.

Experimental Approach: We used heterozygous SERCA2 C674S knock-in (SKI) mice, where half of C674 was substituted by serine, to mimic partial irreversible oxidation of C674.
