Clonality, Mutation and Kaposi Sarcoma: A Systematic Review [PDF]

open access: yesCancers, 2022
Background: It remains uncertain whether Kaposi sarcoma (KS) is a true neoplasm, in that it regresses after removal of the stimulus to growth (as HHV8) when immunosuppression is reduced.

Premalignant Clonal Hematopoiesis (Clonal Hematopoiesis of Indeterminate Potential and Clonal Cytopenia of Undetermined Significance)

Clinics in Laboratory Medicine, 2023
Premalignant clonal hematopoiesis is the presence of somatic alterations in the blood of otherwise healthy individuals. Although the condition is not considered as a cancer, it carries an increased risk of developing a hematologic malignancy, particularly in those with large neoplastic clones, multiple pathogenic mutations, and high-risk mutations.

Clonal Teak

2021
For teak as for most tree species, propagation by seeds remains the easier, the more natural and efficient way to regenerate new plants that are all genetically different from one another. This is essential for ensuring a suitable genetic diversity as well as for genetic improvement through wise breeding practices. However, mass-producing teak planting

Clonality of oligoastrocytomas

Human Pathology, 2002
Oligoastrocytomas (OA) are mixed glial tumors that show morphologic features of both oligodendrogliomas and astrocytomas. The histogenesis of these tumors remains undefined. The aim of this study was to investigate the clonality of OA on the basis of tumor-dependent genetic alterations and tumor-independent X-chromosome inactivation.

Central tolerance: Clonal deletion or clonal arrest?

European Journal of Immunology, 1994
AbstractStudies in various experimental animals have shown that developing T cells with specificity for self antigens can be prevented from maturation at an early stage of development. While several in vitro and in vivo experiments have shown that the mechanism of silencing autospecific T cells is the deletion of immature CD4+8+ thymocytes other ...
