NSUN2-mediated R-loop stabilization as a key driver of bladder cancer progression and cisplatin sensitivity.

R-loops are critical structures that play pivotal roles in regulating genomic stability and modulating gene expression. This study investigates the interactions between the 5-methylcytosine (mC) methyltransferase NOP2/Sun RNA methyltransferase 2 (NSUN2) and R-loops in the transcriptional dynamics and damage repair process of bladder cancer (BCa) cells. We observed markedly elevated levels of R-loops in BCa cells relative to normal urothelial cells.

Sustained yet non-curative response to lenalidomide in relapsed angioimmunoblastic T-cell lymphoma with acquired chidamide resistance: a case report with 10-year follow-up, genetic insights and literature review.

Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive subtype of peripheral T-cell lymphoma (PTCL) characterized by its T-follicular helper (TFH) phenotype. Relapsed and refractory disease is common in AITL and often associated with a poor prognosis. The presence of epigenetic abnormalities, immune dysregulation, hyperinflammation and active angiogenesis in AITL offers potential targets for histone deacetylase (HDAC) inhibitors and immunomodulatory drugs (IMiDs).

STAT2/SLC27A3/PINK1-Mediated Mitophagy Remodeling Lipid Metabolism Contributes to Pazopanib Resistance in Clear Cell Renal Cell Carcinoma.

Clear cell renal cell carcinoma (ccRCC) is a prevalent malignant tumor of the urinary system. While tyrosine kinase inhibitors (TKIs) are currently the first-line treatments for advanced/metastatic ccRCC, patients often develop resistance after TKI therapy. Lipid metabolic reprogramming, a hallmark of tumor progression, contributes to acquired drug resistance in various malignant tumors.

Standard dose anthracycline plus all-trans retinoic acid and arsenic trioxide as induction chemotherapy significantly reduces early death and relapse for high-risk acute promyelocytic leukemia: a single-center real-world analysis.

Background: All-trans retinoic acid (ATRA) and arsenic trioxide (ATO) have revolutionized the treatment of acute promyelocytic leukemia (APL). However, the management of high-risk APL has not been conclusively established. The optimal dosage of anthracycline in the induction has long been debated when ATO is added.

The Mechanism by Which Hedgehog Interacting Protein (HHIP) in Cancer-Associated Fibroblasts Regulate the Secretion of Inflammatory Factors Through the JAK1/STAT3 Pathway Affecting Prostate Cancer Stemness.

Purpose: Prostate cancer (PCa) is seriously affecting men's health and quality of life. Existing studies indicate that PCa stem cells are responsible for promoting the growth and contributing to the high recurrence rate of PCa.

Methods: We retrieved and downloaded PCa-related datasets from both the GEO and TCGA database.

N6-methyladenosine-modified circRPS6KC1 regulated cellular senescence in prostate cancer via FOXM1/PCNA axis.

Prostate cancer (PCa) gradually becomes the most common cancer in men in many countries, of which circRNAs and methylated modification exert an essential role in PCa progression. However, the concrete mechanisms of N6-methyladenosine (m6A) modification of circRNAs in PCa remain unclear. In our study, we identified circRPS6KC1, a novel and up-regulated circular RNA in PCa, through circRNA sequencing.

Dual Hepatic Injury from Refeeding Syndrome and Starvation in a Malnourished Woman After Bariatric Surgery: A Case Report.

BACKGROUND Refeeding syndrome (RFS) and starvation-associated injuries are significant complications in malnourished patients. Severe weight loss after obesity surgery is frequently associated with malnutrition, consequently increasing the likelihood of RFS and starvation-related injuries as postoperative complications. RFS and starvation-induced injury in a single patient has rarely been reported.

Risk assessment of bridge construction investigated using random forest algorithm.

Bridge construction collapse is one of the most common bridge safety accidents. At present, evaluation results are often affected by the ability and experience of the assessor. Therefore, it is difficult to quickly, accurately and effectively evaluate the risk in the process of bridge construction.

Analysis of risk factors for persistent PSA after radical prostatectomy: results from a high-volume center in Southeast China.

Background: For localized prostate cancer, a comprehensive treatment approach centered around radical prostatectomy (RP) is often their optimal choice. Successful RP can typically reduce prostate-specific antigen (PSA) levels to below 0.1 ng/mL within 6 to 8 weeks postoperatively.

Selenomethionine Promotes Milk Protein and Fat Synthesis and Proliferation of Mammary Epithelial Cells through the GPR37-mTOR-S6K1 Signaling.

Selenomethionine (SeMet) is an important nutrient, but its role in milk synthesis and the GPCR related to SeMet sensing is still largely unknown. Here, we determined the dose-dependent role of SeMet on milk protein and fat synthesis and proliferation of mammary epithelial cells (MECs), and we also uncovered the GPCR-mediating SeMet function. At 24 h postdelivery, lactating mother mice were fed a maintenance diet supplemented with 0, 5, 10, 20, 40, and 80 mg/kg SeMet, and the feeding process lasted for 18 days.

Intersection-union dual-stream cross-attention Lova-SwinUnet for skin cancer hair segmentation and image repair.

Skin cancer images have hair occlusion problems, which greatly affects the accuracy of diagnosis and classification. Current dermoscopic hair removal methods use segmentation networks to locate hairs, and then uses repair networks to perform image repair. However, it is difficult to segment hair and capture the overall structure between hairs because of the hair being thin, unclear, and similar in color to the entire image.

PRIORITI: Phase 4 study of triptorelin or active surveillance in high-risk prostate cancer.

Aim: To evaluate the efficacy and safety of triptorelin after radical prostatectomy (RP) in patients with negative lymph nodes.

Methods: PRIORITI (NCT01753297) was a prospective, open-label, randomized, controlled, phase 4 study conducted in China and Russia. Patients with high-risk (Gleason score ≥ 8 and/or pre-RP prostate-specific antigen [PSA] ≥ 20 ng/mL and/or primary tumor stage 3a) prostate adenocarcinoma without evidence of lymph node or distant metastases were randomized to receive triptorelin 11.

SLC44A2 regulates vascular smooth muscle cell phenotypic switching and aortic aneurysm.

Aortic aneurysm is a life-threatening disease with limited interventions that is closely related to vascular smooth muscle cell (VSMC) phenotypic switching. SLC44A2, a member of the solute carrier series 44 (SLC44) family, remains undercharacterized in the context of cardiovascular diseases. Venn diagram analysis based on microarray and single-cell RNA sequencing identified SLC44A2 as a major regulator of VSMC phenotypic switching in aortic aneurysm.

Risk factor analysis and optimal cutoff value selection of PSAD for diagnosing clinically significant prostate cancer in patients with negative mpMRI: results from a high-volume center in Southeast China.

Background: Multi-parametric magnetic resonance imaging (mpMRI) is a diagnostic tool used for screening, localizing, and staging prostate cancer. Patients with Prostate Imaging Reporting and Data System (PI-RADS) score of 1 and 2 are considered negative mpMRI, with a lower likelihood of detecting clinically significant prostate cancer (csPCa). However, relying solely on mpMRI is insufficient to completely exclude csPCa, necessitating further stratification of csPCa patients using biomarkers.

Computer-aided detection of prostate cancer in early stages using multi-parameter MRI: A promising approach for early diagnosis.

Background: Transrectal ultrasound-guided prostate biopsy is the gold standard diagnostic test for prostate cancer, but it is an invasive examination of non-targeted puncture and has a high false-negative rate.

Objective: In this study, we aimed to develop a computer-assisted prostate cancer diagnosis method based on multiparametric MRI (mpMRI) images.

Methods: We retrospectively collected 106 patients who underwent radical prostatectomy after diagnosis with prostate biopsy.

Co-transcriptional R-loops-mediated epigenetic regulation drives growth retardation and docetaxel chemosensitivity enhancement in advanced prostate cancer.

R-loops are prevalent three-stranded nucleic acid structures, comprising a DNA-RNA hybrid and a displaced single-stranded DNA, that frequently form during transcription and may be attributed to genomic stability and gene expression regulation. It was recently discovered that RNA modification contributes to maintain the stability of R-loops such as N6-methyladenosine (mA). Yet, mA-modified R-loops in regulating gene transcription remains poorly understood.

Cancer on motors: How kinesins drive prostate cancer progression?

Prostate cancer causes numerous male deaths annually. Although great progress has been made in the diagnosis and treatment of prostate cancer during the past several decades, much about this disease remains unknown, especially its pathobiology. The kinesin superfamily is a pivotal group of motor proteins, that contains a microtubule-based motor domain and features an adenosine triphosphatase activity and motility characteristics.
