The epitranscriptional factor PCIF1 orchestrates CD8 T cell ferroptosis and activation to control antitumor immunity.

T cell-based immunotherapies have revolutionized cancer treatment, yet durable responses remain elusive. Here we show that PCIF1, an RNA N 2'-O-dimethyladenosine (mA) methyltransferase, negatively regulates CD8 T cell antitumor responses. Whole-body or T cell-specific Pcif1 knockout (KO) reduced tumor growth in mice.

Spatiotemporal crash outliers are also noteworthy: evidence from 13 years of pedestrian-vehicle crashes in North Carolina.

Introduction: Previous research usually focused on high-frequency crash clusters (surrounded by high-frequency crashes), which overlooked outlier locations where high-frequency crashes were surrounded by low-frequency crashes. Neglecting spatiotemporal outliers might overlook critical factors for safety improvements.

Methods: Using pedestrian-vehicle crash data in North Carolina from 2007 to 2019, this study proposes an enhanced spatiotemporal analysis framework (combined with Approximate Nearest Neighbour and the Global Moran I index) to distinguish spatiotemporal crash outliers from aggregated/dispersed patterns.

Enhanced skin penetration of curcumin by a nanoemulsion-embedded oligopeptide hydrogel for psoriasis topical therapy.

Topical delivery of therapeutics on the skin can effectively alleviate skin symptoms of psoriasis and reduce systemic toxicity. However, the low delivery efficiency caused by the stratum corneum barrier limits the therapeutic impact. Here, we reported an oligopeptide hydrogel that encapsulates cell-penetrating-peptide (CPP)-decorated curcumin-loaded nanoemulsions (Cur-CNEs) to enhance the skin penetration of curcumin for topical treatment of psoriasis.

Regulatory significance of terminator: A systematic approach for dissecting terminator-mediated enhancement of upstream mRNA stability.

The primary function of terminators is to terminate transcription in gene expression. Although some studies have suggested that terminators also contribute positively to upstream gene expression, the extent and underlying mechanism of this effect remain largely unexplored. Here, the correlation between terminating strength and upstream mRNA stability was investigated by constructing a terminator mutation library through randomizing 5 nucleotides, assisted by FlowSeq technology, terminator variants were categorized based on the downstream fluorescence intensity, followed by high-throughput sequencing.

Association between serum uric acid and dyslipidaemia in type 2 diabetes: a cross-sectional study.

Background: The association between serum uric acid (SUA) and dyslipidaemia is still unclear in patients with type 2 diabetes mellitus (T2DM). This study aimed to examine the association between SUA and dyslipidaemia and to explore whether there is an optimal SUA level corresponding to the lower risk of suffering from dyslipidaemia.

Research Design And Methods: This cross-sectional study included 1036 inpatients with T2DM and the clinical data were extracted from the hospital medical records.
