USP15 facilitates the progression of bladder cancer by amplifying the activation of the NF-κB signaling pathway.

USP15, a pivotal member of the deubiquitinase family, plays a crucial role in orchestrating numerous vital biological processes, including the regulation of NF-κB signaling pathway and deubiquitination of proto-oncogenes. In various cancers, USP15 has been validated to exhibit up-regulated expression, impacting the initiation and progression of cancer. However, its precise mechanism in bladder cancer remains elusive.

SLC35F2-SYVN1-TRIM59 axis critically regulates ferroptosis of pancreatic cancer cells by inhibiting endogenous p53.

Pancreatic cancer cells undergo intricate metabolic reprogramming to sustain their survival and proliferation. p53 exhibits a dual role in tumor cell ferroptosis. However, the precise role and mechanisms underlying wild-type p53 activation in promoting ferroptosis in pancreatic cancer cells remain obscure.

Laparoscopic bladder diverticulectomy in a child with situs inversus totalis: A case report and literature review.

Situs inversus totalis (SIT) is a rare internal laterality disorder characterized by the mirror arrangement of organs. Multiple gene mutations and maternal environmental factors are thought to cause this variation. It is usually challenging to perform laparoscopic surgery in these cases.

RING-finger protein 6 enhances c-Myc-mediated Warburg effect by promoting MAD1 degradation to facilitate pancreatic cancer metastasis.

Aerobic glycolysis (the Warburg effect) promotes tumor metastasis; hence, drugs targeting its regulators are being developed. c-Myc, a critical transcription factor that regulates the Warburg effect, is involved in the tumorigenesis of many cancers, including pancreatic cancer (PC). However, the upstream regulating mechanisms of c-Myc in PC are unclear.

Bovine Serum Albumin Nanoparticle-Mediated Delivery of Sorafenib for Improving Hepatocellular Carcinoma Therapy.

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver. The majority of patients with HCC are diagnosed with advanced-stage disease. Sorafenib is a frontline therapy drug approved by the Food and Drug Administration for advanced HCC.

MiR-340 regulates the growth and metabolism of renal cell carcinoma cells by targeting frizzled class receptor 3.

MicroRNA(miR)-340 is known as a multifunctional miRNA related to various types of cancer while its role in renal cell carcinoma (RCC) remains to be further investigated. In the present study, an apparent increase in miR-340 expression was observed in both clear cell RCC tissues and RCC cell line 786-O and Caki-1. Functionally, the overexpression of miR-340 promoted cell proliferation, migration, invasion, extracellular alanine (Ala) level, and glycolysis level in 786-O cells.

Recent Developments in Pharmacological Effect, Mechanism and Application Prospect of Diazeniumdiolates.

Nitric oxide (NO) is a simple structured and unstable free radical molecule, which participates in the regulation of many pathophysiological processes. It functions both as a second messenger and as an endogenous neurotransmitter. Diazeniumdiolates (NONOates) are a series of compounds containing the functional parent nuclear structure of [N(O)NO], which are the most widely studied NO donors.

Exploring serum metabolic markers for the discrimination of ccRCC from renal angiomyolipoma by metabolomics.

The discrimination of renal cell carcinoma from renal angiomyolipoma (RAML) is crucial for the effective treatment of each. Serum samples were analyzed by nuclear magnetic resonance spectroscopy-based metabolomics and a number of metabolites were further quantified by HPLC-UV. Clear-cell renal carcinoma (ccRCC) was characterized by drastic disruptions in energy, amino acids, creatinine and uric acid metabolic pathways.

[Eukaryotic translation elongation factor 1A1 positively regulates NOB1 expression to promote invasion and metastasis of hepatocellular carcinoma cells ].

Objective: To explore the role of eukaryotic translation elongation factor 1A1 (eEF1A1) in regulating the invasion and metastasis of hepatocellular carcinoma (HCC) cells and the possible mechanism.

Methods: qRT-PCR and Western blotting were used to detect the mRNA and protein expression of eEF1A1 and NOB1 in different HCC cell lines and normal liver cells. The invasion and migration abilities of HCC cells with eEF1A1 knockdown or overexpression were examined using Transwell chamber assay and RTCA assay, and the changes in NOB1 mRNA and protein expressions in the cells were detected.

Synergistic active targeting of dually integrin αvβ3/CD44-targeted nanoparticles to B16F10 tumors located at different sites of mouse bodies.

Conventional enhanced permeation and retention (EPR) mediates the effects of many drugs, including the accumulation of nanocarriers at tumor sites, but its efficiency remains low. In this study, this limitation was overcome by developing a dual-targeting delivery system based on hyaluronan (HA, a major ligand of CD44) and tetraiodothyroacetic acid (tetrac, a specific ligand of αvβ3), which was exploited to carry docetaxel (DTX) for the synergistic active targeting to tumors. First, a tetrac-HA (TeHA) conjugate was synthesized and grafted onto the surfaces of solid lipid nanoparticles (SLNs) (TeHA-SLNs/DTX), with a high encapsulation efficiency of >91.

Reduction of urinary uric acid excretion in patients with proteinuria.

Serum uric acid (UA) concentration is positively associated with proteinuria. However, the relationship between proteinuria and urinary metabolites of purine metabolism remains unknown. This study developed a hydrophilic interaction chromatography (HILIC)-based HPLC method with ultraviolet detection (UV) to quantify creatinine (Cr), UA, xanthine, and hypoxanthine in human urine simultaneously.

Enhancement of fractionated bone marrow transplantation on hematopoietic cell homing in a mouse allogeneic model.

Background: The conventional method of bone mar row transplantation (BMT) requires a large quantity of bone marrow cells (BMC) transplanted by a single injection. However, the homing efficiency of BMC is low, because the emptying of available niches might be a continuous process after stem-cell death after irradiation. In this article, the death character of CD34 stem cells was directly detected, and a novel method of fractionated (Fr) BMT that aimed to better use each niche that was continuously emptied was developed.
