Sequence diversity in the monooxygenases involved in oxime production in plant defense and signaling: a conservative revision in the nomenclature of the highly complex CYP79 family.

Cytochrome P450 monooxygenases of the CYP79 family catalyze conversion of specific amino acids into oximes feeding into a variety of metabolic plant pathways. Here we present an extensive phylogenetic tree of the CYP79 family built on carefully curated sequences collected across the entire plant kingdom. Based on a monophyletic origin of the P450s, a set of evolutionarily distinct branches was identified.

The Dimensionality of Oral Language in Kindergarten Spanish-English Dual Language Learners.

Purpose: The purpose of this study was to examine the latent dimensionality of language in dual language learners (DLLs) who spoke Spanish as their native language and were learning English as their second language.

Method: Participants included 259 Spanish-English DLLs attending kindergarten. In the spring of their kindergarten year, children completed vocabulary, grammar, listening comprehension, and higher level language measures (comprehension monitoring and inferencing) in Spanish and English.

Common dysregulation of Wnt/Frizzled receptor elements in human hepatocellular carcinoma.

Dysregulation of growth factors and their receptors is central to human hepatocellular carcinoma (HCC). We previously demonstrated that the Frizzled-7 membrane receptor mediating the Wnt signalling can activate the beta-catenin pathway and promotes malignancy in human hepatitis B virus-related HCCs. Expression patterns of all the 10 Frizzled receptors, and their extracellular soluble autoparacrine regulators (19 Wnt activators and 4 sFRP inhibitors) were assessed by real-time RT-PCR in 62 human HCC of different etiologies and their matched peritumorous areas.
