Elucidating PI3K/AKT/PTEN Pathway Alterations at Single‐Cell Level in CTCs From HR+/HER2− Metastatic Breast Cancer

Cancer Science, EarlyView.
Single CTC analysis revealed extensive inter‐ and intra‐patient heterogeneity of PI3K/AKT/PTEN pathway alterations in HR+/HER2− metastatic breast cancer, capturing both SNVs and CNAs, including PTEN loss‐of‐function events. Longitudinal CTC profiling also uncovered dynamic clonal evolution, highlighting its potential to complement tissue and ctDNA ...

Liquid Biopsy and Multi‐Cancer Early Detection Tests for Cancer Screening: A Scoping Review

Clinical Genetics, EarlyView.
There is a large body of evidence on liquid biopsy and multi‐cancer detection tests for cancer screening. Most studies addressed test performance outcomes, while fewer addressed clinical outcomes, implementation, and cost‐effectiveness. No studies evaluated cancer mortality.

Proteomic Analysis of Serum Extracellular Vesicles Revealed Fibulin‐3 as a Novel Predictive Biomarker for Hepatocellular Carcinoma in Patients With Chronic Hepatitis B

Hepatology Research, EarlyView.
We carried out proteomic analysis of serum extracellular vesicles to identify biomarkers predictive of hepatocellular carcinoma (HCC) development in patients with chronic hepatitis B receiving nucleos(t)ide analog therapy. Candidate proteins identified through proteomic analysis were subsequently quantified in serum by ELISA.

Whole-exome sequencing of cell-free DNA and circulating tumor cells in multiple myeloma

Nature Communications, 2018
Circulating tumor cells (CTCs) and cell-free DNA (cfDNA) enables characterization of a patient’s cancer. Here, the authors analyse CTCs, cfDNA, and tumor biopsies from multiple myeloma patients to show these approaches are complementary for mutation ...

Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

Molecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

Circulating tumor cells (CTCs) for the noninvasive monitoring and personalization of non-small cell lung cancer (NSCLC) therapies

, 2019
International audienceGrowing evidences for tumor heterogeneity confirm that single-tumor biopsies frequently fail to reveal the widespread mutagenic profile of tumor. Repeated biopsies are in most cases unfeasible, especially in advanced cancers.

microRNA‐145‐5p regulates P‐glycoprotein and breast cancer resistance protein in primary human fetal brain endothelial cells

The Journal of Physiology, EarlyView.
Abstract figure legend Drug transporters P‐glycoprotein (P‐gp) and breast cancer resistance protein (BCRP) at the blood–brain barrier (BBB) protect the rapidly developing fetal brain. We investigated the role of microRNA‐145‐5p (miR‐145‐5p) microRNA (miRNA) in regulating these key transporters in primary human fetal brain endothelial cells in vitro. We

Isolation and Molecular Characterization of Circulating Tumor Cells [electronic resource] /

The past decade has seen remarkable progress in elucidating the clinical relevance of circulating tumor cells (CTCs). Evidence from numerous clinical studies has unequivocally demonstrated the importance of CTCs as harbingers of poor outcome.

De‐Escalation of Neoadjuvant Treatment for HER2‐Positive Breast Cancer

International Journal of Cancer, Volume 159, Issue 10, Page 2393-2402, 15 November 2026.
ABSTRACT With improved prognosis in early HER2‐positive breast cancer, safely de‐escalating treatment is increasingly investigated to minimize overtreatment. This article focuses on neoadjuvant de‐escalation strategies for HER2‐positive breast cancer.
