CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

False-positive test results: prevalence, time trends, and factors associated with false-positive serological markers in blood donation screening

Hematology, Transfusion and Cell Therapy
Background and Objectives: False-positive serological results in blood donation screening may arise from antibody cross-reactivity, limitations in assay specificity, or low-level reactivity during early-stage infections, ultimately leading to donor ...

Weight of evidence approach using a TK gene mutation assay with human TK6 cells for follow-up of positive results in Ames tests: a collaborative study by MMS/JEMS

Genes and Environment, 2021
Background Conflicting results between bacterial mutagenicity tests (the Ames test) and mammalian carcinogenicity tests might be due to species differences in metabolism, genome structure, and DNA repair systems. Mutagenicity assays using human cells are

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

Molecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

False positive hepatitis B surface antigen after recent vaccination in pregnancy: a diagnostic pitfall

Microbes, Infection and Chemotherapy
We report the case of a 38-year-old pregnant woman who presented with a reactive hepatitis B surface antigen (HBsAg) during routine prenatal screening.

Clinical performance of the urine‐based TERT promoter AbsoluteQ Digital PCR for non‐invasive detection of bladder cancer

Molecular Oncology, EarlyView.
A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.

PECULIARITIES OF CONTROL OF HUMAN ALBUMIN DRUGS ON THE CONTENT OF BACTERIAL ENDOTOXINS

Разработка и регистрация лекарственных средств, 2019
The problem was considered to determine bacterial endotoxins in human albumin drugs. To improve the safety of medicines the option of dual control was recommended, which includes the rabbit pyrogen test and determining bacterial endotoxins by the LAL ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Comparative scores of ABO and Rh hemagglutination reactions

Medical Journal of Dr. D.Y. Patil Vidyapeeth, 2022
Background: Blood group determination is done by the slide test and tube test. Grading/scoring of hemagglutination reactions is performed through the naked eye and microscopy to detect spurious (false positive and negative) reactions.
