Hypermethylated RASAL1's promotive role in chemoresistance and tumorigenesis of choriocarcinoma was regulated by TET2 but not DNMTs.

Background: Patients with choriocarcinoma (CC) accompanying chemoresistance conventionally present a poor prognosis. Whether ras protein activator like-1 (RASAL1) functions as a tumor promoter or suppressor depends on tumor types. However, the role of RASAL1 in process of chemoresistance of CC and underlying molecular mechanism remain elusive.

Single-cell transcriptome profiles the heterogeneity of tumor cells and microenvironments for different pathological endometrial cancer and identifies specific sensitive drugs.

Endometrial cancer (EC) is a highly heterogeneous malignancy characterized by varied pathology and prognoses, and the heterogeneity of its cancer cells and the tumor microenvironment (TME) remains poorly understood. We conducted single-cell RNA sequencing (scRNA-seq) on 18 EC samples, encompassing various pathological types to delineate their specific unique transcriptional landscapes. Cancer cells from diverse pathological sources displayed distinct hallmarks labeled as immune-modulating, proliferation-modulating, and metabolism-modulating cancer cells in uterine clear cell carcinomas (UCCC), well-differentiated endometrioid endometrial carcinomas (EEC-I), and uterine serous carcinomas (USC), respectively.

Methods: Clinical and pathological information from one hundred and ninety-seven patients with cervical AC was collected and analyzed.

[The application value of whole exome sequencing technology in diagnosis of hereditary renal cysts].

The data of 57 renal cyst patients who visited the First Affiliated Hospital of Zhengzhou University from January 2023 to March 2024 were retrospectively analyzed. The age of patients ranged from three months to 60 years old, with 31 males and 26 females. The whole exome sequencing (WES) detected pathogenic or suspected pathogenic (P/LP) variants in 48 renal cystic probands, with a detection rate of 84.

NOP2 facilitates EZH2-mediated epithelial-mesenchymal transition by enhancing EZH2 mRNA stability via m5C methylation in lung cancer progression.

NOP2, a member of the NOL1/NOP2/SUN domain (NSUN) family, is responsible for catalyzing the posttranscriptional modification of RNA through 5-methylcytosine (m5C). Dysregulation of m5C modification has been linked to the pathogenesis of various malignant tumors. Herein, we investigated the expression of NOP2 in lung adenocarcinoma (LUAD) tissues and cells, and found that it was significantly upregulated.

A novel HOIP frameshift variant alleviates NF-kappaB signalling and sensitizes cells to TNF-induced death.

Background: HOIP is the catalytic subunit of the E3 ligase complex (linear ubiquitin chain assembly complex), which is able to generate linear ubiquitin chains. However, the role of rare HOIP functionally deficient variants remains unclear. The pathogenic mechanism and the relationship with immune deficiency phenotypes remain to be clarified.

Causal relationships exist between polycystic ovary syndrome and adverse pregnancy and perinatal outcomes: a Mendelian randomization study.

Introduction: Previous observational studies have shown that polycystic ovary syndrome (PCOS) was associated with adverse pregnancy and perinatal outcomes. However, it remains controversial whether PCOS is an essential risk factor for these adverse pregnancy and perinatal outcomes. We aimed to use instrumental variables in a two-sample Mendelian randomization (MR) study to determine causality between PCOS and adverse pregnancy and perinatal outcomes.

Kidney tea [ (Blume) Miq.] improves diabetic nephropathy via regulating gut microbiota and ferroptosis.

Introduction: Diabetic nephropathy (DN) is the leading cause of end-stage renal disease. Due to its complex pathogenesis, new therapeutic agents are urgently needed. (Blume) Miq.

Fertility preservation in male adolescents with cancer (2011-2020): A retrospective study in China.

Background: According to the studies, more than 80% of pediatric patients with cancer can achieve a survival rate greater than 5 years; however, long-term chemotherapy and/or radiation therapy may seriously affect their reproductive ability. Fertility preservation in adolescents with cancer in China was initiated late, and related research is lacking. Analyze data to understand the current situation and implement measures to improve current practices.

Bacterial load in meconium.

The spike-in plasmid method was utilized to perform an analysis on meconium and second-pass feces, yielding both relative and absolute quantitative results. With the absolute quantitative data, the abundance of bacteria in 17 meconium samples and 17 second-pass fecal samples were found to be 1.14 × 10 and 1.

Molecular findings in patients for whole exome sequencing and mitochondrial genome assessment.

Objective: Whole exome sequencing (WES) is becoming more widely used as a diagnostic tool in the field of medicine. In this article, we reported the diagnostic yield of WES and mitochondrial genome assessment in 2226 consecutive cases in a single clinical laboratory.

Materials And Methods: We retrospectively analyzed consecutive WES reports from 2226 patients with various genetic disorders.

is a prognostic-related biomarker via mediating immune infiltration in lung squamous cell carcinoma (LUSC).

Thymus cell antigen 1 () has been proven to play pivotal roles in many diseases. However, we do not fully understand its functional mechanism, especially in lung squamous cell carcinoma (LUSC). Here, we aimed to perform a comprehensive analysis to explore the expression and prognostic values of in LUSC using bioinformatic technology.

[Clinical analysis of 80 patients with oblique vaginal septum syndrome].

To investigate the clinical features, diagnosis and treatment of oblique vaginal septum syndrome (OVSS). The clinical data of 80 patients with OVSS admitted to The Second Hospital of Hebei Medical University from July 2005 to July 2023 were retrospectively analyzed. According to the classification system of OVSS proposed by Female Genital Anomalies Study Group, Chinese Obstetricians and Gynecologists Association in 2021, the patients were divided into four groups.

Ga-labeled TMTP1 radiotracer for PET imaging of cervical cancer.

Molecular imaging enables visualization and characterization of biological processes that influence tumor behavior and response to therapy. The TMTP1 (NVVRQ) peptide has shown remarkable affinity to highly metastatic tumors and and its potential receptor is aminopeptidase P2. In this study, we have designed and synthesized a Ga-labeled cyclic TMTP1 radiotracer (Ga-DOTA-TMTP1), for PET imaging of cervical cancer.

Noninvasive twin genotyping for recessive monogenic disorders by relative haplotype dosage.

Objective: To establish a haplotype-based noninvasive prenatal testing (NIPT) workflow for single-gene recessive disorders that adapt to dizygotic (DZ) twin pregnancies.

Method: Twin pregnancies at risk of Duchenne muscular dystrophy, Becker muscular dystrophy, hemophilia B, spinal muscular atrophy, phenylketonuria, and nonsyndromic hearing loss were recruited. For subsequent analysis, capture sequencing targeting highly heterozygotic single nucleotide polymorphism sites was conducted.

RNA methylation-related inhibitors: Biological basis and therapeutic potential for cancer therapy.

RNA methylation is widespread in nature. Abnormal expression of proteins associated with RNA methylation is strongly associated with a number of human diseases including cancer. Increasing evidence suggests that targeting RNA methylation holds promise for cancer treatment.

Intraoperative frozen section pathology of vaginal margin in radical hysterectomy on the prognosis and quality of life for patients with IB2-IIA2 cervical cancer: study protocol for a multicenter randomized controlled trial.

Background: Several risk factors have been identified that compromise the treatment outcome in patients with early-to-mid-stage cervical cancer (CC) who are primarily treated with radical surgery. However, there is no report on the impact of intraoperative frozen pathology examination of vaginal margins on the prognosis of patients with CC. This study aimed to conduct a randomized controlled trial (RCT) to determine whether selective vaginal resection can reduce the incidence of operative complications and the risk of postoperative radiotherapy.
