Stresses induced by the deficiency or excess of trace mineral elements, such as manganese (Mn), represent a common limiting factor for the production of crops like Brassica napus. To identify key genes involved in Mn allocation in B. napus and elucidate the underlying mechanisms, a member of the metal tolerance protein (MTP) family obtained in the previous screening of cDNA library of B. napus under Mn stress was selected as the research subject. Based on the sequence information and phylogenetic analysis, it was named as BnMTP10. It belongs to the Mn-cation diffusion facilitator (CDF) subfamily. Expression of BnMTP10 in yeast significantly improved the tolerance of transformants to excessive Mn and iron (Fe) and reduced the accumulation of Mn and Fe. However, the yeast transformants exhibited no significant changes in tolerance to excess cadmium, boron, aluminum, zinc, or copper. The qRT-PCR results demonstrated that the flowers of B. napus had the highest expression of BnMTP10, followed by roots and leaves. Subcellular localization studies revealed that BnMTP10 was localized in the endoplasmic reticulum (ER). Compared with wild-type plants, transgenic Arabidopsis overexpressing BnMTP10 exhibited enhanced tolerance to excessive Mn stress but showed no significant difference under Fe stress. Correspondingly, under excessive Mn stress, the Mn content in the roots of transgenic Arabidopsis increased significantly. However, under excessive Fe stress, the Fe content in transgenic Arabidopsis did not alter significantly. According to the results, we hypothesize that BnMTP10 may alleviate excessive Mn stress in plants by mediating Mn transport to the ER. This study facilitated our understanding of efficient mineral nutrients, and provided theoretical foundations and gene resources for breeding B. napus.

The ataxia telangiectasia mutated(ATM)gene is an important tumor suppressor gene and a key effector gene in regulating the repair of double-strand DNA breaks.It plays an indispensable role in maintaining genetic stability,facilitating cell cycle arrest,and modulating cell apoptosis.When the ATM gene mutates,it fails to effectively induce the phosphorylation of downstream targets,leading to impaired DNA repair mechanisms,genetic instability,and chromosomal structural abnormalities,ultimately promoting abnormal proliferation of tumor cells.Analysis of next-generation sequencing(NGS)datas reveals a relatively high mutation rate of the ATM gene in bladder cancer cells.Relevant studies have shown that ATM gene regulates the proliferation,invasion,and metastasis of bladder cancer cells through the signaling pathways such as nuclear transcription factor-κB(NF-κB)and Interferon-γ(IFNγ).Mutanted ATM gene can enhance patients'sensitivity to radiotherapy and chemotherapy,and boost the efficacy of immunotherapy,resulting in a generally better prognosis for patients with ATM gene mutation.This finding marks ATM gene as a potential therapeutic target and predictive prognosis biomarker for bladder cancer patients.Therefore,this article will comprehensively review the research on the ATM gene in bladder cancer from 3 aspects:the structural characteristics of the ATM gene and its tumor-suppressing and tumor-promoting functions,the mechanism of action of the ATM gene in the occurrence and development of bladder cancer,and the impact of the ATM gene on the treatment and prognosis of bladder cancer patients.Additionally,the future research directions of the ATM gene was prospected,with the aim of providing new targets for the drug treatment of bladder cancer,and bringing new hope for the treatment of bladder cancer patients.

Ferroptosis is a form of iron dependent cell death,which is closely related to the progress and prognosis of bladder cancer(BCa).Among them,erroptosis related genes(FRGs)play an important role in the biological effects of BCa,such as participating in regulating the proliferation,migration,metastasis,drug resistance,immune regulation,and therapeutic efficacy of BCa cells.In addition,FRGs are also important biomarkers for predicting the prognosis of tumor patients.However,the specific mechanism of action of FRGs in BCa remains elusive.How to use FRGs to predict the prognosis of BCa and guide the treatment of BCa is still in the exploratory stage.Therefore,exploring the regulatory and predictive role of FRGs in BCa is particularly important for the diagnosis and treatment of BCa.This article aims to systematically elucidate the role of FRGs in the occurrence,development,treatment,and prognosis of BCa.To provide theoretical reference for further exploring the treatment of refractory and drug-resistant BCa patients,and constructing prognostic risk prediction models.

Objective:This study aimed to analyze cytomegalovirus (CMV) reactivation and its influencing factors in patients with B-lymphocyte malignancy who received chimeric antigen receptor T (CAR-T) cell therapy.Methods:This study retrospectively reviewed patients with B-lymphocyte malignancy who received CAR-T cell therapy in the First Affiliated Hospital of Soochow University from January 2021 to December 2023. The data of patients who underwent CMV-DNA detection and/or pathogen metagenomic sequencing twice or more within 100 days after CAR-T cell therapy were analyzed. The clinical characteristics of the CMV reactivation and non-activation groups were compared. The factors related to CMV reactivation were analyzed with the Chi-square test and nonparametric rank sum test, and the risk factors were examined with Logistic regression.Results:This study included 86 patients, among whom 18 (20.9%) had CMV reactivation, and the median time of reactivation was 20 (1-95) days. All of the 18 patients had CMV viremia, and no CMV disease was observed. Seven patients turned to the latent state after continuing acyclovir antiviral therapy, and 11 patients returned to the latent state after upgrading the antiviral therapy to first-line drugs, including ganciclovir and foscarnet sodium. Six or more courses of anti-tumor treatment before CAR-T cell therapy, allogeneic hematopoietic stem cell transplantation within 2 years before CAR-T cell therapy, non-remission before treatment, and the use of high-dose glucocorticoids and/or tocilizumab were related to CMV reactivation, among which allogeneic hematopoietic stem cell transplantation within 2 years pre-treatment and the use of high-dose glucocorticoids and/or tocilizumab treatment were independent risk factors for CMV reactivation.Conclusion:Patients with B-lymphocyte malignancy who received CAR-T cell therapy have the risk of CMV reactivation, especially for those who received allogeneic hematopoietic stem cell transplantation within 2 years pre-treatment and those who received high-dose glucocorticoids and/or tocilizumab treatment.
