Construction of the bromodomain-containing protein-associated prognostic model in triple-negative breast cancer.

Background: Bromodomain-containing protein (BRD) play a pivotal role in the development and progression of malignant tumours. This study aims to identify prognostic genes linked to BRD-related genes (BRDRGs) in patients with triple-negative breast cancer (TNBC) and to construct a novel prognostic model.

Methods: Data from TCGA-TNBC, GSE135565, and GSE161529 were retrieved from public databases.

Long-term outcomes of intrathoracic versus cervical anastomosis after esophagectomy: A large-scale propensity score matching analysis.

Background: Esophageal squamous cell carcinoma is a prevalent and aggressive gastrointestinal tumor, particularly in East Asia. However, there is a lack of consensus on the long-term survival outcomes of intrathoracic anastomosis and cervical anastomosis following esophagectomy. This study aims to provide a comprehensive summary of the long-term survival outcomes of these 2 anastomosis techniques.

Awareness, attendance, and attitudes toward cervical cancer screening among HIV-positive Chinese women in Yunnan province: a cross-sectional study.

A mobile double-suspension technology for single-port D2 distal gastrectomy: A technical note with video vignette.

Technique: The single-incision laparoscopic gastrectomy(SILG) for gastric cancer is challenging due to limited surgical fields. Thus, we have developed a novel, moble suspension technique for single-port D2 distal gastrectomy. This method was applied in our center and the surgical procedure which presented in this study is accompanied by a video for a more detailed understanding.

Exploring the genetic associations and causal relationships between antibody responses, immune cells, and various types of breast cancer.

Background: There may be potential associations between various pathogens, antibody immune responses, and breast cancer (BC), but the specific mechanisms and causal relationships remain unclear.

Methods: First, multiple Mendelian randomization (MR) methods were used for univariable MR analysis to explore potential causal relationships between 34 antibody immune responses (related to 12 pathogens), 46 antibody immune responses (related to 13 pathogens), antibody responses post-COVID-19 vaccination, 731 immune cell types, and various BC subtypes (including overall BC, ER-positive, ER-negative, Luminal A, Luminal B, Luminal B HER2-negative, HER2-positive, and triple-negative BC). The primary results were then subjected to reverse MR analysis, heterogeneity testing using Cochran's Q, and horizontal pleiotropy testing.

Novel Tree Shrew-Derived Antimicrobial Peptide with Broad-Spectrum Antibacterial Activity.

The number of cationic residues and net charge are critical for the activity of antimicrobial peptides (AMPs) due to their role in facilitating initial electrostatic interactions with negatively charged bacterial membranes. A cathelicidin AMP (TC-33) has been identified from the Chinese tree shrew in our previous work, which exhibited weak antimicrobial activity, likely due to its moderately cationic nature. In the current study, based on TC-33, we designed a novel AMP by peptide truncation and Glu substitutions to increase its net cationic charge from +4 to +8.

Targeting the SPC25/RIOK1/MYH9 Axis to Overcome Tumor Stemness and Platinum Resistance in Epithelial Ovarian Cancer.

In epithelial ovarian cancer (EOC), platinum resistance, potentially mediated by cancer stem cells (CSCs), often leads to relapse and treatment failure. Here, the role of spindle pole body component 25 (SPC25) as a key determinant promoting stemness and platinum resistance in EOC cells, with its expression being correlated with adverse clinical outcomes is delineated. Mechanistically, SPC25 acts as a scaffolding platform, orchestrating the assembly of an SPC25/RIOK1/MYH9 trimeric complex, triggering RIOK1-mediated phosphorylation of MYH9 at Ser1943.

The intra-tumoral microbiome as a potential biomarker of response to external beam radiation therapy in cervical cancer.

Background: We aimed to determine the potential predictive value of the intra-tumoral microbiome as a marker of the response to external beam radiation therapy (EBRT) in cervical cancer (CC).

Methods: A prospective longitudinal trial of 36 CC patients receiving pelvic radiotherapy was designed to investigate microbial characteristic signatures and diversity (alpha and beta) of multiple sites (tumor, vaginal, gut, urethral, and oral) in the superior response (SR) and inferior response (IR) groups of CC patients by 16S rRNA sequencing. Utilized the least absolute shrinkage and selection operator (LASSO) logistic regression method to analyze clinicopathological factors that potentially influenced the efficacy of EBRT.

miRNA-105-5p regulates the histone deacetylase HDAC2 through FOXG1 to affect the malignant biological behavior of triple-negative breast cancer cells.

Background: Triple-negative breast cancer (TNBC) is a specific subtype of breast cancer (BC). Some potential molecular targets have been identified, and miR-105-5p was found to be abnormally expressed in TNBC tissues.

Objective: The objective of this study was to probe the effect of miR-105-5p on TNBC via FOXG1/HDAC2-mediated acetylation.

Construction and validation of a prediction model for inguinal lymph node metastasis of penile malignancy.

Background: Penile squamous cell carcinoma is a relatively rare malignancy among male malignancies, there are more than 30,000 new cases and more than 10,000 deaths of penile cancer annually. In patients with penile malignancy, inguinal lymph node metastasis (ILNM) significantly reduces patient survival. Thus, we identified the risk factors for ILNM in penile malignancies, aiming to develop a precise prediction model.

Telomeres and telomerase in Sarcoma disease and therapy.

Sarcoma is a rare tumor derived from the mesenchymal tissue and mainly found in children and adolescents. The outcome for patients with sarcoma is relatively poor compared with that for many other solid malignant tumors. Sarcomas have a highly heterogeneous pathogenesis, histopathology and biological behavior.

Development and validation of the head and neck cancer psychosocial distress scale (HNCPDS) to identify patients at high risk for psychological problems : a multicenter study.

To develop the Head and Neck Cancer Psychosocial Distress Scale (HNCPDS) with the aim of identifying high-risk individuals for psychosocial distress among patients, and to assess its reliability, validity and applicability. Using the classical test theory, a total of 435 head and neck cancer patients from six tertiary hospitals in China were recruited for developing the HNCPDS. Delphi expert consultation and item analysis were used to improve the content validity of the preliminary HNCPDS.

Hepatitis B virus infection and the risk of gynecologic cancers: a systematic review and meta-analysis.

Objectives: The relationship between hepatitis B virus (HBV) infection and gynecologic cancers is controversial. We aimed to evaluate the risk of gynecologic cancers associated with HBV infection using a meta-analysis.

Methods: Two independent reviewers identified publications in the PubMed, Embase and Cochrane Library databases that reported an association between HBV and the risk of gynecologic malignancy from inception to December 31, 2022.

Interaction of ncRNAs and the PI3K/AKT/mTOR pathway: Implications for osteosarcoma.

Osteosarcoma (OS) is the most common primary malignant bone tumor in children and adolescents, and is characterized by high heterogeneity, high malignancy, easy metastasis, and poor prognosis. Recurrence, metastasis, and multidrug resistance are the main problems that limit the therapeutic effect and prognosis of OS. PI3K/AKT/mTOR signaling pathway is often abnormally activated in OS tissues and cells, which promotes the rapid development, metastasis, and drug sensitivity of OS.

TC-14, a cathelicidin-derived antimicrobial peptide with broad-spectrum antibacterial activity and high safety profile.

Cathelicidins, a major class of antimicrobial peptides (AMPs), hold considerable potential for antimicrobial drug development. In the present study, we identified a novel cathelicidin AMP (TC-33) derived from the Chinese tree shrew. Despite TC-33 demonstrating weak antimicrobial activity, the novel peptide TC-14, developed based on its active region, exhibited a 432-fold increase in antimicrobial activity over the parent peptide.
