Ferroptosis was discovered and named by the laboratory of Brent Stockwell at Columbia University in 2012. Ferroptosis has become a research hotspot in the fields of life sciences, medicine and chemistry, and it now plays a significant role in the development and progression of major diseases such as neoplasms, neurodegenerative diseases, tissue and organ damage, and immune-related diseases. Non-Hodgkin lymphoma (NHL) is the most common type of lymphoma which ranks as the third most frequent malignant tumor in children in China. This paper reviews the research progress of the relationship between ferroptosis and NHL, with a particular focus on Burkitt lymphoma and diffuse large B-cell lymphoma.

Thymoma is a malignant tumor originating from thymus epithelial cells, with an incidence of 1.3-2.6 per million. Due to its low incidence, lack of cells and animal models, there are relatively few studies on thymoma, and its diagnosis and treatment progress is relatively slow. The update of 5th edition of WHO Classification of Thoracic Tumors in 2021 and the NCCN( National Comprehensive Cancer Network) Clinical Practice Guidelines in Oncology: Thymoma and Thymoma Cancer in 2024 put forward many new views and suggestions on the diagnosis and treatment strategy of thymoma. This article reviews the research and treatment of thymoma based on the latest research progress in recent years, aiming to improve the clinician's understanding of thymoma, provide reference for treatment, and promote the research of thymoma.

Objective This study aims to investigate the effects of FGL2 on the immune response of EBV-infected T cells,including their activation,proliferation,exhaustion,and cytokine profile changes.Methods Primary T cells were infected with EBV at different multiplicities of infection(MOI).Expression of FGL2 in T cells,as well as T-cell activation,proliferation,exhaustion,and cytokine levels,were detected using RT-qPCR,Western blot,ELISA,CCK8,and flow cytometry(FCM),respectively.Further experiments involving FGL2 knockdown and overexpression were conducted to elucidate its specific regulatory role in EBV-infected T cells.Results FGL2 expression was significantly upregulated in EBV-infected T cells(P＜0.05).EBV infection also induced enhanced T cell activation(P＜0.001),proliferation(P＜0.001),and exhaustion(P＜0.01).Compared to the T cells+EBV group,the T cells+EBV+FGL2 overexpression group exhibited higher exhaustion levels(P＜0.01),reduced activation(P＜0.05)and proliferation(P＜0.05),decreased pro-inflammatory cytokine levels(P＜0.05),and increased anti-inflammatory cytokine levels(P＜0.05).Conversely,the T cells+EBV+FGL2 knockdown group demonstrated the opposite trends,with elevated activation(P＜0.01),proliferation(P＜0.05),pro-inflammatory cytokine levels(P＜0.05),and reduced exhaustion(P＜0.01)and anti-inflammatory cytokine levels(P＜0.05).Conclusion FGL2 suppresses T cell activation and proliferation,exacerbates T cell exhaustion,inhibits pro-inflammatory cytokine release,and promotes anti-inflammatory cytokine secretion during EBV infection,thereby modulating the immune response of T cells.

Objective To study the expression of amplified in breast cancer 1(AIB1)and ankyrin repeat domain containing11(ANKRD11/ANCO1)in human papillomavirus(HPV)positive cervical cancer and their relationship with clinicopathological characteristics and their predictive value for postoperative recurrence.Methods Cancer tissues and paracancer tissues of 94 HPV positive cervical cancer patients who visited the Third People's Hospital of Mianyang from January 2018 to January 2020 were selected,while 50 HPV negative cervical cancer tissues during this period were taken as controls.Real-time qPCR(RT-qPCR)was conducted to detect AIB1 mRNA and ANCO1 mRNA expression in cancer tissue and paracancer tissues of HPV positive cervical cancer and cancer tissue of HPV negative cervical.Pearson analysis of the correlation between AIB1 mRNA and ANCO1 mRNA expression in HPV positive cervical cancer tissues.Logistic regression analysis was used to identify the risk factors for postoperative recurrence of HPV-positive cervical cancer patients.The predictive value of AIB1 mRNA,ANCO1 mRNA,and their combination in predicting postoperative recurrence in HPV positive cervical cancer patients was analyzed by receiver operating characteristic curve.Results Compared to the adjacent tissues of HPV positive cervical cancer and cancer tissues of HPV negative cervical cancer,AIB1 mRNA(3.04±0.37 vs 0.87±0.21,1.02±0.33)in HPV positive cervical cancer tissues was higher,while ANCO1 mRNA(1.13±0.26 vs 1.91±0.35,1.82±0.36)was lower,with significant differences(t=68.499,53.137;23.649,17.434,all P<0.05).The expression of AIB1 mRNA and ANCO1 mRNA in HPV positive cervical cancer tissues showed a negative correlation(r=-0.714,P<0.001).Compared to patients with FIGO stage ⅡA～ⅡB and without lymph node metastasis,AIB1 mRNA(3.88±0.32 vs 2.04±0.41,4.46±0.33 vs 2.16±0.46)in HPV positive cervical cancer tissues with FIGO stage ⅡA and lymph node metastasis was higher,while ANCO1 mRNA(0.67±0.29 vs 1.68±0.20,0.49±0.24 vs 1.53±0.32)was lower,with significant differences(t=24.425,26.097;19.288,16.777,all P<0.001).FIGO stage ⅡA,lymph node metastasis,and high AIB1 mRNA[OR(95％CI)=1.644(1.223～2.210),1.779(1.295～2.444),1.247(1.050～1.728)]were risk factors for postoperative recurrence in HPV positive cervical cancer patients,while high ANCO1 mRNA[(OR(95％CI):0.634(0.451～0.891)]was a protective factor.The AUC(95％CI)of AIB1 mRNA and ANCO11 mRNA combined for predicting postoperative recurrence in HPV positive cervical cancer patients was 0.914(0.863～0.952),which was higher than the single indicator detection of 0.821(0.782～0.869)and 0.794(0.763～0.847),and the differences were significant(Z=4.123,4.432,all P<0.001).Conclusion The expression of AIB1 mRNA is increased and the expression of ANCO1 mRNA is reduced in HPV positive cervical cancer tissue,which are related to the occurrence and progression of cancer.The combination of the two has a high predictive value for evaluating postoperative recurrence.

Objective:To explore the regulation mechanism of the quorum sensing regulator AphA on the functional activity of type Ⅵ secretion system VflT6SS2 in Vibrio fluvialis. Methods:Western Blot analysis was used to detect the relative expression and secretion of VflT6SS2 signature component hemolysin-coregulated protein (Hcp) in wild type (WT), Δ aphA, and corresponding complementary strains. Quantitative reverse transcription PCR and luminescence activity assay of the promoter- lux fusion system was used to measure the mRNA expression levels and promoter activity of the VflT6SS2 core and accessory gene-cluster representative genes tssB2, hcp ( tssD2) and vgrG ( tssI2), and the quorum sensing regulator HapR in WT and Δ aphA strains. A point mutation experiment combined with a luminescence activity assay was used to verify the regulatory binding site of AphA in the tssD2b promoter region. Electrophoretic mobility shift assay (EMSA) was used to determine AphA binding to the hapR promoter. Results:The mRNA expression levels of tssB2, hcp( tssD2), vgrG ( tssI2), and hapR as well as the protein expression and secretion levels of Hcp in Δ aphA strain, were significantly higher than those in the WT strain. The promoter activities of the VflT6SS2 core cluster, tssD2a, tssI2a, and hapR were higher in Δ aphA strain than in the WT strain, while the promoter activity of tssD2b showed the opposite trend. The promoter sequence analysis of tssD2a and tssD2b found significant differences in the region from -335 bp to -229 bp, and two potential AphA binding sites on tssD2b. The promoter activity of tssD2b decreased significantly after the point mutation of the two potential AphA binding sites. EMSA results showed that AphA binds directly to the promoter region of hapR. Conclusions:AphA indirectly inhibits the regulation of the VflT6SS2 core and accessory gene clusters at the promoter level by directly repressing the expression of hapR. AphA showed opposite regulation patterns for tssD2a and tssD2b, and AphA could positively regulate the expression of tssD2b by directly binding to the tssD2b promoter region (-335 bp to -229 bp).
