Species formation is usually accompanied by chromosomal reorganization. Thus, even very closely related species frequently differ in chromosome number (polyploidy, aneuploidy, centric increase or decrease) or in gene sequence (inversions, centric shifts, translocations). The question arises whether such karyotypic changes are incidental or whether there is some causal relationship with the spec...
Previous reports have demonstrated that human embryonic stem cells (hESCs) tend to develop genomic alterations and progress to a malignant state during long-term in vitro culture. This raises concerns of the clinical safety in using cultured hESCs. However, transformed hESCs might serve as an excellent model to determine the process of embryonic stem cell transition. In this study, ITRAQ-based ...
Metaphase karyotype investigation on two allopatric strains of Anopheles nitidus Harrison, Scanlon, and Reid (Diptera: Culicidae) was conducted in Thailand during 2011-2012. Five karyotypic forms, i.e., Form A (X1, Y1), Form B (X1, Y2), Form C (X2, Y3), Form D (X1, X3, Y4), and Form E (X1, X2, X3, Y5) were obtained from a total of 21 isofemale lines. Forms A, B, and C were confined to Phang Nga...
Focal segmental glomerulosclerosis (FSGS) is a major cause of familial nephrotic syndrome. We generated 20 induced pluripotent stem cell lines from patients diagnosed with FSGS. The iPSC include 8 female and 12 male cover donor age range 31 to 78. were peripheral blood mononuclear cells by integration-free reprogramming using Sendai virus vectors. Cell fully characterized regarding their plurip...
Seven consecutive ascitic tumors were obtained over a 9-month period from a patient with serous adenocarcinoma of the ovary. The tumor cell populations were analyzed for cellular proliferation (labeling index, agar clonogenicity, and self-renewal capacity), for cell differentiation (cell surface expression of carcinoembryonic antigen and histochemical stain for fat accumulation), and for karyot...
Acute promyelocytic leukemia (APL) is a well-defined entity among acute leukemia, cytogenetically characterized by a t(15;17) (q22;q11-12) translocation. In vitro and in vivo studies suggest that all-trans retinoic acid (RA) treatment restores cell maturation. We have isolated the first permanent cell line with t(15;17), derived from the marrow of a patient with APL in relapse. The establishmen...
Loricariidae is one of the largest fish families of the world, with about 650 species separated into six subfamilies. To date, cytogenetic data on only 56 species of this family are available. In the present study, the karyotypes of three Ancistrinae species and five Loricariinae species were studied. The lowest diploid number, 2n=38, was observed in Ancistrus n.sp. 1 (Ancistrinae) and the high...
