Cytogenetical Studies on Camellia Species : II. The Karyotype Analysis in C. sinensis and C. wabiske
Curcumin is a major component of the curcuma species, commonly used as a yellow coloring and flavoring agent in foods. Curcumin has been demonstrated to have potent antioxidant, anti-inflammatory activity and has shown anticancer properties in many rodent models. There is the perception that since compounds are natural, they are devoid of toxicity and safe to use. Some of the active compounds i...
Spiny rats of the genus Proechimys are morphologically diverse, widely distributed and have diploid numbers ranging from 2n = 14-16 to 2n = 62. In this paper we present cytogenetical data and brief comments on morphological and biogeographical issues related to spiny rats. In our sample of 42 spiny rats collected from 12 Brazilian Amazonian tropical rainforest and the Cerrado (Brazilian savanna...
A cytogenetical study of 25 Lepilemur from the north of Madagascar has given evidence for six karyotypes (with four diploid numbers). Four of the karyotypes with these diploid numbers--2N = 38, 2N = 36, 2N = 34--we believe evolved from one another by centric fusion; and two karyotypes resulted from the hybridization of two of these (2N = 37 and 2N = 35). The different karyotypes distinguish the...
A cytogenetic study was carried out on the chromosomes and the nuclear DNA content of the freshwater goby Economidichthys pygmaeus (Pisces, Gobiidae). The species is characterized by a 2n=46 karyotype consisting of 12 submetacentric and 11 subtelocentric chromosome pairs (NF=70). Major (45S) rDNA genes are terminal-centromeric located on the short arm of a single medium-small sized submetacentr...
We describe a new PDGFRB fusion associated with a t(5;14)(q33;q24) in a patient with a longstanding chronic myeloproliferative disorder with eosinophilia. After confirmation of PDGFRB involvement and definition of the chromosome 14 breakpoint by fluorescence in situ hybridization, candidate partner genes were selected on the basis of the presence of predicted oligomerization domains believed to...
