Somatic Host Cell Alterations in HPV Carcinogenesis

High-risk human papilloma virus (HPV) infections cause cancers in different organ sites, most commonly cervical and head and neck cancers. While carcinogenesis is initiated by two viral oncoproteins, E6 and E7, increasing evidence shows the importance of specific somatic events in host cells for malignant transformation. HPV-driven cancers share characteristic somatic changes, including apolipo...

A study of somatic chromosomes in a Japanese population.

THE CHROMOSOMES OF HUMAN BEINGS, in various tissues, have been investigated with a variety of methods by many authors since the end of the last century. Early investigators found that the approximate chromosome number for man was from 16 to 32 until the appearance of de Winiwarter's historic paper in 1912 reporting 47 chromosomes in human males (cf. Makino, 1956). Later, Painter (1923) reported...

Affinity Distance Values among Somatic Metaphase Chromosomes

In maize root-tip metaphase preparations, all distances between two chromosomes were measured in 50 cells from each of seven stocks and in 30 from one stock; four were arrested with cold, two with 8-hydroxyquinoline, one with colchicine and one with monobromonaphthalene Standardized, affinity-distance values were calculated for all pairs of homologues and pairs of nonhomologues from each prepar...

Somatic Mosaicism in Cases with Small Supernumerary Marker Chromosomes

Somatic mosaicism is something that is observed in everyday lives of cytogeneticists. Chromosome instability is one of the leading causes of large-scale genome variation analyzable since the correct human chromosome number was established in 1956. Somatic mosaicism is also a well-known fact to be present in cases with small supernumerary marker chromosomes (sSMC), i.e. karyotypes of 47,+mar/46....
