High Sensitivity of Circulating Tumor Cells Derived from a Colorectal Cancer Patient for Dual Inhibition with AKT and mTOR Inhibitors

Cells, 2020
Circulating tumor cells (CTCs) are cells shed from the primary tumor into the bloodstream. While many studies on solid tumor cells exist, data on CTCs are scarce. The mortality of cancer is mostly associated with metastasis and recent research identified

Circulating Tumor Cells in the Adenocarcinoma of the Esophagus [PDF]

International Journal of Molecular Sciences, 2016
Circulating tumor cells (CTCs) are elements of indisputable significance as they seem to be responsible for the onset of metastasis. Despite this, research into CTCs and their clinical application have been hindered by their rarity and heterogeneity at the molecular and cellular level, and also by a lack of technical standardization.

EpCAM-Expressing Circulating Tumor Cells in Colorectal Cancer

The International Journal of Biological Markers, 2017
Background Several studies have raised the issue of the inadequacy of CellSearch ® to detect the entire pool of circulating tumor cells (CTCs) from blood of cancer patients, suggesting that cells expressing low levels of epithelial cell adhesion molecule

Multiplex detection of ten ESR1 mutations and AKT1 E17K in breast cancer using digital PCR

The Journal of Liquid Biopsy
Introduction: ESR1 mutations are now established as a key mechanism of resistance to endocrine therapy in estrogen-receptor–positive breast cancer (ER​+ ​breast cancer) and their sensitive and specific detection in plasma-cell free DNA (plasma-cfDNA) is ...

PIK3CA hotspot mutations in circulating tumor cells and paired circulating tumor DNA in breast cancer: a direct comparison study

Molecular Oncology, 2019
Liquid biopsy analysis, mainly based on circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA), provides an extremely powerful tool for the molecular profiling of cancer patients in real time.

A fatal affair: Circulating tumor cell relationships that shape metastasis

iScience, 2021
Summary: Circulating tumor cells are metastatic precursors in several cancer types. Their biology and clinical utility are subject to numerous investigations, yet one aspect that is often neglected is their entanglement with the tumor microenvironment ...

The Value of Circulating Tumor Cells and Tumor Markers Detection in Lung Cancer Diagnosis

Technology in Cancer Research & Treatment, 2023
Objective Circulating tumor cells are complete tumor cells with multi-scale analysis values that present a high potential for lung cancer diagnosis. To enhance the accuracy of lung cancer diagnosis, we detected circulating tumor cells by the innovated ...

Identification and clinical implications of circulating cancer associated fibroblasts in lung cancer patients

Advances in Cancer Biology - Metastasis, 2023
Objectives: In tumor microenvironment (TME), cancer-associated fibroblasts (CAFs) are known to expedite cancer progression (metastasis). CAF-secreted cytokines confer a survival advantage to circulating tumor stem cells (CTSCs) (indicators of residual ...

Circulating tumor cells: A surrogate to predict the effect of treatment and overall survival in gastric adenocarcinoma

The International Journal of Biological Markers, 2021
Background: Circulating tumor cells and serum tumor markers have been found significant in predicting outcome for several malignancies. However, their role in gastric cancer is not fully clarified.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.
