cell free dnas (cfdnas) are small fragments of genomic or mitochondrial dna releasing from cells into the blood stream. the presence of cfdna in the human circulatory system has been shown for the first time in 1948 however, the potential clinical applications of cfdna remained unknown until recent progress in detection and quantification of these molecules by sensitive methods. in this paper, ...

Circulating tumor cells (CTCs) are gaining momentum as a diagnostic tool and therapeutic target. CTC clusters more metastatic, but harder to study characterize, because they rare the methods of isolation mostly focused on single CTCs. This review highlights recent advances our understanding cell with emphasis their composition, origin, biology, detection, impact metastasis survival. New approac...

OBJECTIVE Circulating tumor cells are isolated tumor cells in the peripheral blood that serve as important prognostic indicators for many kind of tumors. The study was conducted to know the rate of detection of circulating tumor cells among breast cancer patients in comparison with benign breast diseases and control subjects and to know the association between CTC positivity and various clinico...

Abstract The transcription factor TCF-1 is essential for the development and function of T regulatory (Treg) cells, however its poorly understood. Here, we show that primarily suppresses genes are co-bound by Foxp3. Single-cell RNA-seq analysis identified effector- central-memory Treg-cells with differential expression Klf2 memory activation markers. deficiency did not change core Treg transcri...

Epithelial-to-mesenchymal transition (EMT) endows epithelial cells with enhanced motility and invasiveness, allowing them to participate in many physiological and pathological processes. Epithelial-to-mesenchymal transition contributes to the generation of circulating tumor cells (CTCs) in epithelial cancers because it increases tumor cell invasiveness, promotes tumor cell intravasation and ens...
