Circulating tumor cells: advancing personalized therapy in small cell lung cancer patients

Molecular Oncology, EarlyView.
Small cell lung cancer (SCLC) is an aggressive form of lung cancer that spreads rapidly to secondary sites such as the brain and liver. Cancer cells circulating in the blood, “circulating tumor cells” (CTCs), have demonstrated prognostic value in SCLC, and evaluating biomarkers on CTCs could guide treatment decisions such as for PARP inhibitors ...

Efficacy of platelet transfusion in cardiac surgery

Platelets, 2022
Massive diffuse bleeding is still a problem in cardiovascular surgery. The first line treatment is platelet concentrate transfusion, although there is still insufficient information regarding efficacy, quantity, and timing.

Anti-platelet factor 4/polyanion antibodies mediate a new mechanism of autoimmunity [PDF]

, 2020
Antibodies recognizing complexes of the chemokine platelet factor 4 (PF4-CXCL4) and polyanions (P) opsonize PF4-coated bacteria hereby mediating bacterial host defense. A subset of these antibodies may activate platelets after binding to PF4-heparin complexes, causing the prothrombotic adverse drug reaction heparin-induced thrombocytopenia (HIT).

RGS10 shapes the hemostatic response to injury through its differential effects on intracellular signaling by platelet agonists. [PDF]

, 2018
Platelets express ≥2 members of the regulators of G protein signaling (RGS) family. Here, we have focused on the most abundant, RGS10, examining its impact on the hemostatic response in vivo and the mechanisms involved.

Intravascular tissue factor initiates coagulation via circulating microvesicles and platelets [PDF]

, 2003
Although tissue factor (TF), the principial initiator of physiological coagulation and pathological thrombosis, has recently been proposed to be present in human blood, the functional significance and location of the intravascular TF is unknown.

A comparative study of circulating tumor cell isolation and enumeration technologies in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells were spiked into donor blood to evaluate the recovery rates of the following circulating tumor cell (CTC) enrichment technologies: CellMag™, EasySep™, RosetteSep™, Parsortix® PR1, and Parsortix® Prototype systems. Each method's advantages and disadvantages are described.

Anti-GPVI (HY101) activates platelets in a multicolor flow cytometry panel

Platelets, 2022
The platelet transmembrane receptor GPVI can be assessed together with other platelet membrane markers in a whole blood multicolor flow cytometry panel. The advantage of combining multiple antibodies in a single tube is the possibility of distinguishing ...

Strengthening from dislocation restructuring and local climb at platelet linear complexions in Al-Cu alloys [PDF]

arXiv, 2023
Stress-driven segregation at dislocations can lead to structural transitions between different linear complexion states. In this work, we examine how platelet array linear complexions influence dislocation motion and quantify the associated strengthening effect in Al-Cu alloys using atomistic simulations.

Circulating tumor DNA (ctDNA) trajectories predict survival in trifluridine/tipiracil‐treated metastatic colorectal cancer patients

Molecular Oncology, EarlyView.
The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...

TSST-1 protein exerts indirect effect on platelet activation and apoptosis

Platelets, 2022
Thrombocytopenia or platelet dysfunction is a risk factor for severe infection. Staphylococcus aureus (S. aureus) releases a variety of virulence factors especially toxic shock syndrome toxin 1 (TSST-1), which may cause toxic shock syndrome. S.
