Objective To explore the role of neogambogic acid in the characteristics of colorectal cancer stem cells (CRC-CSCs) through the Wnt/β-catenin signaling pathway. Methods The colorectal cells SW480 and HCT166 were divided into control group and neogambogic acid groups (1.5, 3, 6, and 12 μmol/L). The viability of CRC-CSCs was determined by MTT method, and spheroid and clone formation assays were used to assess the capacity of spheroid formation and self-renewal ability of the cells. The effects of neogambogic acid on the apoptosis and cell cycle of CRC-CSCs were evaluated by flow cytometry assays. Real-time quantitative PCR was used to detect the mRNA expression levels of relative markers (CD133, CD44, ALDH1, Oct4, and Nanog) of CRC-CSCs, and the protein expression levels of the self-renewal marker (PCNA), apoptosis markers (cleaved caspase-3 and cleaved caspase-9), and Wnt/β-catenin signaling pathway markers (p-GSK3β, GSK3β, β-catenin, and Wnt) were analyzed using Western blot. Results Compared with the control group, after neogambogic acid treatment, the viability of SW480 and HCT116 cells decreased (P<0.05), the spheroid forming ability and the clone numbers of CRC-CSCs decreased (P<0.001, P<0.01) but the cell apoptosis rate increased (P<0.01), and cell cycle was arrested in G0/G1 phase. Moreover, neogambogic acid downregulated the mRNA and protein expression of relative markers of CRC-CSCs (CD133, CD44, ALDH1, Oct4, and Nanog), PCNA, p-GSK3β, β-catenin, and Wnt (P<0.05) and upregulated the expression of cleaved caspase-3, cleaved caspase-9, and GSK3β (P<0.01). Conclusion Neogambogic can inhibit the stem cell properties of colorectal cells via inhibition of Wnt/β-catenin signaling pathway. As a result, neogambogic acid may be an attractive agent against colorectal cancer.

Although clinical evidence suggests that nonalcoholic fatty liver disease is an established major risk factor for heart failure, it remains unexplored whether sleep disorder-caused hepatic damage contributes to the development of cardiovascular disease (CVD). Here, our findings revealed that sleep fragmentation (SF) displayed notable hepatic detrimental phenotypes, including steatosis and oxidative damage, along with significant abnormalities in cardiac structure and function. All these pathological changes persisted even after sleep recovery for 2 consecutive weeks or more, displaying memory properties. Mechanistically, persistent higher expression of nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) in the liver was the key initiator of SF-accelerated damage phenotypes. SF epigenetically controlled the acetylation of histone H3 lysine 27 (H3K27ac) enrichment at the Nox4 promoter and markedly increased Nox4 expression in liver even after sleep recovery. Moreover, fine coordination of the circadian clock and hepatic damage was strictly controlled by BMAL1-dependent Sirtuin 1 (Sirt1) transcription after circadian misalignment. Accordingly, genetic manipulation of liver-specific Nox4 or Sirt1, along with pharmacological intervention targeting NOX4 (GLX351322) or SIRT1 (Resveratrol), could effectively erase the epigenetic modification of Nox4 by reducing the H3K27ac level and ameliorate the progression of liver pathology, thereby counteracting SF-evoked sustained CVD. Collectively, our findings may pave the way for strategies to mitigate myocardial injury from persistent hepatic detrimental memory in diabetic patients.

A major obstacle in type 2 diabetes mellitus (T2DM) is sleep fragmentation (SF), which negatively affects testicular function. However, the underlying mechanisms remain to be elucidated. In this study, we demonstrate that SF induces testicular damage through a mechanism involving lipid metabolism, specifically mediated by melatonin (MEL) receptor 1a (MT1). T2DM mice with SF intervention displayed several deleterious phenotypes such as apoptosis, deregulated lipid metabolism, and impaired testicular function. Unexpectedly, sleep recovery (SR) for 2 consecutive weeks could not completely abrogate SF's detrimental effects on lipid deposition and testicular function. Interestingly, MEL and MT1 agonist 2-iodomelatonin (2IM) effectively improved lipid homeostasis, highlighting MEL/2IM as a promising therapeutic drug for SF-trigged testicular damage. Mechanistically, MEL and 2IM activated FGFR1 and sequentially restrained the crosstalk and physical interaction between TAB1 and TAK1, which ultimately suppressed the phosphorylation of TAK1 to block lipid deposition and cell apoptosis caused by SF. The ameliorating effect of MEL/2IM was overtly nullified in Fgfr1 knockout (Fgfr1-KO +/- ) diabetic mice. Meanwhile, testicular-specific overexpression of Tak1 abolished the protective effect of FGF1mut on diabetic mouse testis. Our findings offer valuable insights into the molecular mechanisms underlying the testicular pathogenesis associated with SF and propose a novel therapeutic approach for addressing male infertility in T2DM.

Objective:To investigate the clinical manifestations, pathological features, treatment methods and prognosis of primary renal synovial sarcoma (PRSS) in order to improve the clinical understanding and treatment level of the disease.Methods:The clinical data, pathological features, immunohistochemical indexes, SYT gene detection, treatment and follow-up results of 21 patients with PRSS reported in the First Affiliated Hospital of Soochow University from 2018 to 2023 were retrospectively analyzed. Kaplan-Meier method was used to calculate the relationship between age and cumulative survival rate. Results:The male to female ratio of PRSS patients was 16∶5, the ratio of left and right kidneys was 7∶14, the median age was 50 years old, the mean age was 44.5 years old, the median tumor length diameter was 9.7 cm, and the mean tumor length diameter was 6.7 cm. 57%(12/21) reported low back pain and 48%(10/21) reported gross hematuria. Immunohistochemical examination showed 100% positive for Vimentin(16/16), BCL-2(18/18) and TLE-1(10/10), 69%(9/13) and 85%(6/7) positive for CD99 and CD56, respectively. Genetic testing found SYT translocation signal in 92% of cases (12/13). Next generation sequencing (NGS) detected SS18- SSX1 fusion in 2 cases and SS18- SSX2 fusion in 1 case. SS18- SSX1+ S18- SSX2 fusion was found in 1 case, and one case of SS18- NEDD4 fusion occurred. Preoperative neoadjuvant chemotherapy was performed in 2 cases, postoperative chemotherapy in 11 cases, postoperative chemoradiotherapy in 2 cases, and surgery only in 5 cases. All patients were followed up for 3 to 42 months, and 4 cases were lost to follow-up. Patients with younger onset had a longer cumulative survival time. Patients had a median survival time of 13 months and a mean survival time of 15.4 months. Conclusions:PRSS is more common in middle-aged men, the right kidney is easy to occur, the length of the mass is usually >7 cm, most cases can be initially diagnosed by pathologic morphology, immunophenotype, fluorescence in situ hybridization or NGS STY gene detection can provide accurate diagnosis. The prognosis of PRSS is very poor, and the cumulative survival rate is negatively correlated with the age of onset. Surgical resection combined with chemotherapy is the main treatment for PRSS.
