Prostate specific antigen (PSA) is widely used in liquid biopsy of prostate cancer (PCa) but still faces challenges due to the poor specificity. Herein, this study reports a double-SERS satellite immunoassay, made of an Au-Ag dealloyed intra-nanogap nanoflower (Au-Ag DINF) with strong SERS signals and Au magnetic nanoparticles (AuMNPs) with magnetic capture and SERS amplification, for sensing multiple PSA (free PSA (fPSA), complexed PSA (cPSA) and [-2]proPSA (p2PSA)) toward potential PCa screening. Unlike the previous studies focus on the tPSA and fPSA/tPSA ratio (f/t PSA%), this work introduces a multiple PSA-mediated Prostate Health Index (PHI) assay with significantly increased the predictive accuracy and specificity of PCa, especially the patients with a tPSA level in the "diagnostic gray zone".

Transarterial chemoembolization (TACE) utilizing a water-in-oil lipiodol emulsion is a preferable therapeutic strategy for advanced liver cancer in clinical practice. However, the low stability of the lipiodol emulsion and poor efficacy of chemotherapeutic drug seriously undermine the efficiency of TACE. Herein, a novel lobaplatin-loaded lipiodol emulsion (denoted as ICN-LPE) is developed by constructing a lipiodol Pickering emulsion (LPE) stabilized with iron-doped carbon nanozymes (ICN) to mitigate the issue of lipiodol-water separation.

Tank-binding kinase 1 (TBK1) is a critical signal transducer in the nuclear factor κB (NF-κB) and interferon regulatory factor (IRF) pathways, essential for innate immunity. However, its negative regulation mechanisms remain unclear. This study demonstrates that TBK1 succinylation, regulated by desuccinylase SIRT5, inhibits lipopolysaccharide (LPS)/Toll-like receptor 4 (TLR4)-mediated NF-κB and IRF signaling activation.

Pericytes, the mural cells that envelop small blood vessels, play crucial roles in the formation of the blood-brain barrier (BBB). Here, we present a protocol for generating a pericyte reporter zebrafish line Ki(pdgfrb-P2A-GAL4-VP16) using a CRISPR-Cas9-mediated knockin technique. We describe steps for identifying efficient single guide RNA (sgRNA), constructing donor plasmid, and generating and maintaining the knockin line.

Background: Digestive system malignancies, including esophageal carcinoma (ESCA), stomach adenocarcinoma (STAD), liver hepatocellular carcinoma (LIHC), and colon adenocarcinoma (COAD), pose significant global health challenges. Identifying shared and distinct regulatory mechanisms across these cancers can lead to improved therapies. This study aims to construct and compare competing endogenous RNA (ceRNA) networks across ESCA, STAD, LIHC, and COAD to identify RNA biomarkers that could serve as precision therapeutic targets to enhance clinical outcomes and advance personalized cancer care.

Background: Cardiovascular disease (CVD) is the leading cause of noncancer-related mortality among differentiated thyroid cancer (DTC) survivors, which accounts for a large portion of subsequent primary malignancies in childhood cancer survivors. This study aims to assess the risk of cardiovascular mortality among DTC as a second primary malignancy (DTC-2) patients compared with DTC as a first primary malignancy (DTC-1) and the general population.
Methods: Using the Surveillance, Epidemiology, and End Results database, we conducted a population-based cohort study including 159 395 DTC-1 and 20 010 DTC-2 patients diagnosed older than 30 between 1975 and 2020 and the corresponding US population (71 214 642 person-years; 41 420 893 cardiovascular deaths).

Restoration of disc height and biomechanical function is essential for intervertebral disc degeneration (IDD) treatment. Removing abnormal nucleus pulposus (NP) tissue is an important step to facilitate bony fusion during the healing process. We analyzed publicly available single-cell transcriptome data for human normal and degenerative NP to identify genes associated with NP degeneration.

Objective: Lung squamous cell carcinoma (LUSC) constitutes approximately 40% of lung cancer cases and lacks effective treatments, needing new diagnostic and prognostic tools. Macrophage scavenger receptor 1 (MSR1), as a key receptor in macrophages, is essential in tumor immunity. However, its mechanisms in regulating tumor progression and immunity and its prognostic value in LUSC remain unclear.

PFKP Phosphofructokinase, Platelet Type isoform), as an essential metabolic enzyme, contributes to the high glycolysis rates seen in cancers while its role in oncogenic pathways, especially from a non-metabolic aspect, is not fully understood. We found that PFKP was highly expressed in NSCLC and was related to poor patient survival. Knockdown of PFKP significantly inhibited cell proliferation, colony formation, invasion, and migration of NSCLC cells.

Kodamaea ohmeri infection is a relatively rare condition, primarily affecting immunocompromised individuals or those with a history of invasive procedures. The diagnosis of this infection is challenging because of its diverse and complex atypical clinical presentations. In this study, we describe a case of cutaneous infection with Kodamaea ohmeri presenting as erythematous and scaly lesions on both armpits and groin with itching in an 82-year-old man, mimicking intertrigo, and review the relevant literature.

Background: Metabolic-associated fatty liver disease (MAFLD) is a public health concern. Transforming growth factor-β1(TGF-β1) plays an important regulatory role in multiple MAFLD stages, as it can promote the expression of matrix metalloproteinase-9 (MMP9) and promote liver fibrosis. Sorting nexin protein-10 (SNX-10) may be involved in the occurrence and development of fatty liver disease.

Promoting wound nerve regeneration and synchronously initiating angiogenesis are critical factors in the healing process of diabetic wounds. However, existing research on diabetic wounds mainly focuses on angiogenesis, bacterial infection and reactive oxygen species, often failing to coordinate neurogenesis and angiogenesis. To coordinate the symbiosis of nerves and blood vessels in the diabetic wounds, we successfully designed a multifunctional chitosan (CS)-based sponges by regulating the structure of CS specifically for diabetic wound healing.

Progranulin (PGRN) is overexpressed and implicated in hepatocellular carcinoma (HCC) development; however, its post-translational modifications and regulatory mechanisms in HCC remain largely unexplored. Here, the expression levels of PGRN, OGT, and O-GlcNAcylation were found to be elevated in both HCC samples and cell lines. LC-MS/MS analysis and immunoprecipitation revealed that PGRN underwent O-linked N-acetylglucosamine (O-GlcNAc) modification at threonine 272 (Thr272).

Numerous studies have substantiated the pivotal role of long non-coding RNAs (lncRNAs) in the progression of non-small cell lung cancer (NSCLC) and the prognosis of afflicted patients. Notably, individuals with NSCLC may exhibit heightened vulnerability to the novel coronavirus disease (COVID-19), resulting in a more unfavorable prognosis subsequent to infection. Nevertheless, the impact of COVID-19-related lncRNAs on NSCLC remains unexplored.
