Co-blocking TIGIT and PVRIG using a novel bispecific antibody enhances anti-tumor immunity.

TIGIT and PVRIG are immune checkpoints co-expressed on activated T and NK cells, contributing to tumor immune evasion. Simultaneous blockade of these pathways may enhance therapeutic efficacy, positioning them as promising dual targets for cancer immunotherapy. This study aimed to develop a bispecific antibody (BsAb) to co-target TIGIT and PVRIG.

Defect Migration and Phase Transformations in Two-Dimensional Iron Chloride inside Bilayer Graphene.

The intercalation of metal chlorides, and particularly iron chlorides, into graphitic carbon structures has recently received lots of attention, as it can not only protect this two-dimensional (2D) magnetic system from the effects of the environment but also substantially alter the magnetic, electronic, and optical properties of both the intercalant and host material. At the same time, intercalation can result in the formation of structural defects or defects can appear under external stimuli, which can affect materials performance. These aspects have received so far little attention in dedicated experiments.

Identification of crucial pathways and genes linked to endoplasmic reticulum stress in PCOS through combined bioinformatic analysis.

Background: Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic condition impacting millions of women worldwide. This study sought to identify granulosa cell endoplasmic reticulum stress (GCERS)-related differentially expressed genes (DEGs) between women with PCOS and those without PCOS using bioinformatics and to investigate the related molecular mechanisms.

Methods: Two datasets were downloaded from GEO and analysed using the limma package to identify DEGs in two groups-PCOS and normal granulosa cells.

Methylation of and Are Risk Factors and Potential Biomarkers for Cervical Lesions.

Background: The correlation between methylation of paired box gene 1 () and sex determining region Y-box 1 () with human papillomavirus (HPV) infection and the progression of cervical lesions is not well understood. This study aims to explore the potential value of and as diagnostic biomarkers for cervical diseases.

Methods: A total of 139 cervical biopsy tissue samples were obtained from the Department of Pathology, the Seventh Medical Center, Chinese PLA General Hospital from 2021 to 2023.

Correlation Between PIK3R1 Expression and Cell Growth in Human Breast Cancer Cell Line BT-474 and Clinical Outcomes.

Background: While mutations in the gene play important roles in human breast carcinogenesis, gene alterations are recognized as actionable mutations for clinical cancer treatment. We aimed to elucidate the role of PIK3R1 in cell proliferation on breast carcinoma and to correlate the PIK3R1 expression with patients' outcome using human tumor tissue arrays.

Methods: Using human BT-474 (estrogen receptor (ER)+/human epidermal growth factor receptor 2 (HER2)-high) breast carcinoma cell line as model, the role of PIK3R1 in cell proliferation was elucidated by knock-down of the gene (ΔPIK3R1) in this cell line.
