Pharmacological activation of aldehyde dehydrogenase 2 inhibits ferroptosis via SLC7A11/GPX4 axis to reduce kidney stone formation.

Calcium oxalate (CaOx) kidney stones pose a global health challenge due to their high prevalence and recurrence rates. While cell death mechanisms such as ferroptosis are known to play a crucial role in stone formation, the precise underlying mechanisms remain enigmatic. Aldehyde dehydrogenase 2 (ALDH2) is a metabolic enzyme of the ferroptosis product 4-hydroxy-2-nonenal (4-HNE).

Monoacylglycerol lipase blockades the senescence-associated secretory phenotype by interfering with NF-κB activation and promotes docetaxel efficacy in prostate cancer.

Metabolic reprogramming and cellular senescence greatly contribute to cancer relapse and recurrence. In aging and treated prostate, persistent accumulating senescence-associated secretory phenotype (SASP) of cancer cells often limits the overall survival of patients. Novel strategic therapy with monoacylglycerol lipase (MGLL) upregulation that counters the cellular and docetaxel induced SASP might overcome this clinical challenge in prostate cancer (PCa).

Dysregulated palmitic acid metabolism promotes the formation of renal calcium-oxalate stones through ferroptosis induced by polyunsaturated fatty acids/phosphatidic acid.

The pathogenesis of renal calcium-oxalate (CaOx) stones is complex and influenced by various metabolic factors. In parallel, palmitic acid (PA) has been identified as an upregulated lipid metabolite in the urine and serum of patients with renal CaOx stones via untargeted metabolomics. Thus, this study aimed to mechanistically assess whether PA is involved in stone formation.

Unveiling novel insights in prostate cancer through single-cell RNA sequencing.

Single-cell RNA sequencing (scRNA-seq) is a cutting-edge technology that provides insights at the individual cell level. In contrast to traditional bulk RNA-seq, which captures gene expression at an average level and may overlook important details, scRNA-seq examines each individual cell as a fundamental unit and is particularly well-suited for identifying rare cell populations. Analogous to a microscope that distinguishes various cell types within a tissue sample, scRNA-seq unravels the heterogeneity and diversity within a single cell species, offering great potential as a leading sequencing method in the future.

P300/SP1 complex mediating elevated METTL1 regulates CDK14 mRNA stability via internal m7G modification in CRPC.

Background: N7-methylguanosine (m7G) modification is, a more common epigenetic modification in addition to m6A modification, mainly found in mRNA capsids, mRNA interiors, transfer RNA (tRNA), pri-miRNA, and ribosomal RNA (rRNA). It has been found that m7G modifications play an important role in mRNA transcription, tRNA stability, rRNA processing maturation, and miRNA biosynthesis. However, the role of m7G modifications within mRNA and its "writer" methyltransferase 1(METTL1) in tumors, particularly prostate cancer (PCa), has not been revealed.

[Corrigendum] CDCA5 promotes the progression of prostate cancer by affecting the ERK signalling pathway.

Subsequently to the publication of the above paper, an interested reader drew to the authors' attention that a pair of the data panels showing the results of Transwell invasion assays (specifically, the 'C4‑2 / shCON' and the PC‑3 / CON panels) featured in Fig. 3F on p. 927 contained overlapping sections, such that data that were intended to show the results from differently performed experiments appeared to have been derived from the same original source.

HOXB3 drives WNT-activation associated progression in castration-resistant prostate cancer.

Enabled resistance or innate insensitiveness to antiandrogen are lethal for castration-resistant prostate cancer (CRPC). Unfortunately, there seems to be little can be done to overcome the antiandrogen resistance because of the largely unknown mechanisms. In prospective cohort study, we found that HOXB3 protein level was an independent risk factor of PSA progression and death in patients with metastatic CRPC.

Characteristics of and antibiotic resistance in urinary tract pathogens isolated from patients with upper urinary tract stones.

To investigate the distribution characteristics and antibiotic resistance patterns of uropathogens in patients with upper urinary calculi and urinary tract infections, data on sex, age, positive midstream urine culture results and drug sensitivity results were collected. The statistical program SPSS 26.0 was used for statistical analysis.

TEAD3 inhibits the proliferation and metastasis of prostate cancer via suppressing ADRBK2.

TEAD3 acts as a transcription factor in many tumors to promote tumor occurrence and development. But in prostate cancer (PCa), it appears as a tumor suppressor gene. Recent studies have shown that this may be related to subcellular localization and posttranslational modification.

Circular RNAs in Prostate Cancer: Is it Time to Further Explore Liquid Biopsies?

Background: Although diagnosis and treatment of prostate cancer (PCa) have evolved rapidly in recent years, clinically significant molecular biomarkers are still needed to lower the mortality. Circular RNAs (circRNAs) are a poorly characterized component of PCa transcriptome. Recently, since the development of deep RNA sequencing and novel bioinformatic pipelines, emerging evidence suggests circRNAs to have diverse functions in the development and progression of PCa.

Alterations of plasma exosomal proteins and motabolies are associated with the progression of castration-resistant prostate cancer.

Background: Current diagnosis tools for prostate cancer (PCa) such as serum PSA detection and prostate biopsy cannot distinguish dormant tumors from invasive malignancies, either be used as prognosis marker for castration resistant prostate cancer (CRPC), the lethal stage of PCa patients. Exosomes have been widely investigated as promising biomarkers for various diseases. We aim to characterize the proteomic and metabolomic profile of exosomes and to evaluate their potential value for the diagnosis of PCa, especially CRPC.

Androgen deprivation restores ARHGEF2 to promote neuroendocrine differentiation of prostate cancer.

Androgen receptor (AR) plays an important role in the progression of prostate cancer and has been targeted by castration or AR-antagonists. The emergence of castration-resistant prostate cancer (CRPC) after androgen deprivation therapy (ADT) is inevitable. However, it is not entirely clear how ADT fails or how it causes resistance.

Identification of LAT/ZAP70 characterized immune subtypes of prostate cancer.

Background: While immunotherapy has shown potent efficacy in clinical practices, patient selection to receive checkpoint blockade is still challenging in prostate cancer (PCa). LAT and ZAP70 functions in lymphocyte activation and plays a critical role in T cell receptor (TCR) signal transduction. However, PCa genomic and clinical data regarding the role of LAT and ZAP70 are limited.

YAP1-TEAD1 mediates the perineural invasion of prostate cancer cells induced by cancer-associated fibroblasts.

Perineural invasion (PNI) driven by the tumor microenvironment (TME) has emerged as a key pattern of metastasis of prostate cancer (PCa), while its underlying mechanism is still elusive. Here, we identified increased CAFs and YAP1 expression levels in patients with metastatic PCa. In the cultured PCa cell line LNCaP, co-culture with cancer-associated fibroblasts (CAFs) could upregulate YAP1 protein expression.

One-Stage Flexible Ureteroscopy during Single-Tract Percutaneous Nephrolithotomy in the Treatment of Parallel Calyceal Stones.

Introduction: The aim of this study was to compare the clinical safety and efficiency between one-stage flexible ureteroscopy (FURS) during single-tract percutaneous nephrolithotomy (PCNL) and multi-tract PCNL in the treatment of parallel calyceal stones.

Methods: One hundred and twenty-five patients who had calyceal stones parallel to puncture channel from March 2017 to January 2021 were enrolled and assigned into two groups. Seventy cases received the treatment of FURS combined with single-tract PCNL under the oblique supine position (the Combined group), and 55 cases had multi-tract PCNL procedure under the prone position (the Multi-tract group).

hsa_circ_0092339 acts as a molecular sponge in castration-resistant prostate cancer via the hsa-mir-940/ axis.

We aimed to determine whether intronic circRNA acts as a molecular sponge in castration-resistant prostate cancer (CRPC). A gene chip technique was used to conduct sequencing. A qPCR experiment was performed to verify the result.

The cell cycle gene centromere protein K () contributes to the malignant progression and prognosis of prostate cancer.

Background: The cell cycle gene centromere protein K () is upregulated in various cancers; however, the clinical value and mechanism of in prostate cancer (PCa) and castration-resistant prostate cancer (CRPC) remain unclear.

Methods: The expression of in PCa was analyzed in both patients with PCa and cell lines using immunohistochemistry (IHC), real-time quantitative reverse transcription PCR (qRT-PCR), Western blot and bioinformatics analyses. Knockdown of in PCa cells was achieved by transfecting siRNAs and assessed using qRT-PCR and Western blotting.

Assessing the Potential Prognostic and Immunological Role of TK1 in Prostate Cancer.

It has been reported that thymidine kinase 1 (TK1) was up-regulated in multiple malignancies and participated in the regulation of tumor malignant behavior. However, its specific role in prostate cancer (PCa) remains unclear. TK1 expression in PCa patients and cell lines was identified via crossover analysis of the public datasets.
