ROS Responsive Cerium Oxide Biomimetic Nanoparticles Alleviates Calcium Oxalate Crystals Induced Kidney Injury via Suppressing Oxidative Stress and M1 Macrophage Polarization.

Emerging studies have demonstrated that M1 macrophage polarization and oxidative stress play important roles in calcium oxalate (CaOx) induced kidney injury, which leads to increased crystals deposition. ROS scavenging nanozymes and kidney-targeted nanoparticles for antioxidant drugs delivery have emerged as an arisen methodology for kidney injury therapy. However, cell membrane biomimetic-modified nanozymes as anti-inflammatory drug delivery systems for the treatment of kidney injury is rarely reported.

miR-5100 Overexpression Inhibits Prostate Cancer Progression by Inducing Cell Cycle Arrest and Targeting E2F7.

Despite advances in treatment, prostate cancer remains a leading cause of cancer-related deaths among men, highlighting the urgent need for innovative therapeutic strategies. MicroRNAs (miRNAs) have emerged as key regulatory molecules in cancer biology. In this research, we investigated the tumor-suppressive role of miR-5100 in PCa and its underlying molecular mechanism.

Recent Advances of Neoadjuvant Immunotherapy for Urothelial Bladder Cancer.

Urothelial bladder cancer is one of the most common malignant tumors of the urinary system, which accounts for 90~95% of urothelial carcinoma. Despite the current standard neoadjuvant management for localized urothelial MIBC (T2-4cN0M0) is cisplatin-based chemotherapy before radical cystectomy, there still had poor performances and less overall survival benefits in patients with localized urothelial MIBC. Moreover, nearly half of MIBC patients were ineligible for receiving cisplatin because of chronic kidney disease and performance status.

Cell membrane coated nanoparticles as a biomimetic drug delivery platform for enhancing cancer immunotherapy.

Cancer immunotherapy, a burgeoning modality for cancer treatment, operates by activating the autoimmune system to impede the growth of malignant cells. Although numerous immunotherapy strategies have been employed in clinical cancer therapy, the resistance of cancer cells to immunotherapeutic medications and other apprehensions impede the attainment of sustained advantages for most patients. Recent advancements in nanotechnology for drug delivery hold promise in augmenting the efficacy of immunotherapy.

The Application of Nanoparticles Targeting Cancer-Associated Fibroblasts.

Cancer-associated fibroblasts (CAF) are the most abundant stromal cells in the tumor microenvironment (TME), especially in solid tumors. It has been confirmed that it can not only interact with tumor cells to promote cancer progression and metastasis, but also affect the infiltration and function of immune cells to induce chemotherapy and immunotherapy resistance. So, targeting CAF has been considered an important method in cancer treatment.

The application of nanoparticles-based ferroptosis, pyroptosis and autophagy in cancer immunotherapy.

Immune checkpoint blockers (ICBs) have been applied for cancer therapy and achieved great success in the field of cancer immunotherapy. Nevertheless, the broad application of ICBs is limited by the low response rate. To address this issue, increasing studies have found that the induction of immunogenic cell death (ICD) in tumor cells is becoming an emerging therapeutic strategy in cancer treatment, not only straightly killing tumor cells but also enhancing dying cells immunogenicity and activating antitumor immunity.

Recent Advances in Nanomaterials for the Treatment of Acute Kidney Injury.

Acute kidney injury (AKI) is a serious clinical syndrome with high morbidity, elevated mortality, and poor prognosis, commonly considered a "sword of Damocles" for hospitalized patients, especially those in intensive care units. Oxidative stress, inflammation, and apoptosis, caused by the excessive production of reactive oxygen species (ROS), play a key role in AKI progression. Hence, the investigation of effective and safe antioxidants and inflammatory regulators to scavenge overexpressed ROS and regulate excessive inflammation has become a promising therapeutic option.

Antioxidant nanozymes in kidney injury: mechanism and application.

Excessive production of reactive oxygen species (ROS) in the kidneys is involved in the pathogenesis of kidney diseases, such as acute kidney injury (AKI) and diabetic kidney disease (DKD), and is the main reason for the progression of kidney injury. ROS can easily lead to lipid peroxidation and damage the tubular epithelial cell membrane, proteins and DNA, and other molecules, which can trigger cellular oxidative stress. Effective scavenging of ROS can delay or halt the progression of kidney injury by reducing inflammation and oxidative stress.

The role of circular RNA in tumor microenvironment and immunotherapy.

Cancer immunotherapy has favorable efficacy in various types of tumors, and has become an important weapon in the treatment of tumors in recent years. Long noncoding RNAs and microRNAs have been identified to play important roles in regulating cancer immunotherapy. Circular RNAs (circRNAs) are involved in the pathological process of many diseases, especially cancer.

CircRPPH1 accelerates the proliferation and migration of bladder cancer via enhancing the STAT3 signaling pathway.

Bladder cancer (BCa) is a common malignant disease with high recurrence and variable prognosis. Circular RNAs (circRNAs) are implicated in the development of multiple diseases. However, the biological activities of circRNAs in BCa remain largely elusive.

Predictive value of CD3 cells and interleukin 2 receptor in systemic inflammatory response syndrome after percutaneous nephrolithotomy.

Objective: The aim of the current study was to evaluate the risk factors that influence the development of postoperative systemic inflammatory response syndrome (SIRS) after percutaneous nephrolithotomy (PCNL), including cytokines and lymphocyte subsets.

Methods: A total of 154 patients who underwent PCNL at our hospital between October 2019 and January 2022 were retrospectively reviewed. The development of post-PCNL SIRS was the primary endpoint of the study.

PODNL1 promotes cell migration and regulates the epithelial/mesenchymal transition process in bladder cancer.

PODNL1, a member of the small leucine-rich proteoglycans family, has been identified to be closely associated with the prognosis of ovarian cancer and glioma. In this study, we explored the role of PODNL1 in the progression of bladder cancer (BLCA). TCGA data analysis showed that the expression level of PODNL1 in BLCA tissues was significantly higher than that in adjacent tissues.

Comparison of the oncological, perioperative and functional outcomes of partial nephrectomy versus radical nephrectomy for clinical T1b renal cell carcinoma: A systematic review and meta-analysis of retrospective studies.

Objective: To conduct a meta-analysis assessing the perioperative, functional and oncological outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) for T1b tumours. The primary endpoints were the oncological outcomes. The secondary endpoints were the perioperative and functional outcomes.

The presence of intraductal carcinoma of the prostate is closely associated with poor prognosis: a systematic review and meta-analysis.

We aimed to confirm the predictive ability of the presence of intraductal carcinoma of the prostate (IDC-P) for prognosis and the associations between IDC-P and clinicopathological parameters. Studies were identified in PubMed, Cochrane Library, EMBASE, Web of Science, and SCOPUS up to December 1, 2019. Hazard ratios (HRs) for survival data and odds ratios for clinicopathological data with 95% confidence intervals (CIs) were extracted.
