Short communication: duplication in the 5'-flanking region of the beta-lactoglobulin gene is linked to the BLG A allele

beta-Lactoglobulin (beta-LG) is the major whey protein in the milk of cows and other ruminants. It is well established that the predominant genetic variants beta-LG A and B are differentially expressed. Extensive investigation of the genetic variation in the promoter region of the BLG gene revealed the existence of specific haplotypes associated with the A and B variants. However, the genetic basis for the differentially expressed BLG A and B alleles is still elusive. In this study additional genetic variation further upstream in the 5'-flanking region of the BLG gene was identified, including 6 single nucleotide substitutions, a single nucleotide deletion, and a 7-bp duplication. Comparison of DNA sequences showed that the investigated 5'-flanking region is highly conserved between ruminants, and the duplication g.-1885_-1879dupCTCTCGC and the substitution g.-1888A>G are only found in the BLG A and D alleles in cattle. The cytosine at position g.-1957 and the thymines at positions g.-2008 and g.-2049 are only found in BLG B alleles of cattle. It is suggested that the described genetic variability contributes to the differential allelic expression of the BLG gene.

Multimodal viral communication: a social semiotic analysis of the popular Spanish "Ola ke ase" meme

Multimodality – the interdependence of semiotic resources in text – is an existential element of today’s media. The term multimodality attends systematically to the social interpretation of a wide range of communicational forms used in meaning making. A primary focus of social- semiotic multimodal analysis is on mapping how modal resources are used by people in a given social context. In November 2012 the “Ola ke ase” catchphrase, which is a play on “Hola ¿qué hace?”, appeared for the first time in Spain and immediately has been adopted as a Twitter hashtag and an image macro series. Its viral spread on social networks has been tremendous, being a trending topic in various Spanish-speaking countries. The objective of analysis is how language and image work together in the “Ola ke ase” meme. The interplay between text and image in one of the original memes and some of its variations is quantitatively analysed applying a social-semiotic approach. Results demonstrate how the “Ola ke ase” meme functions through its multimodal character and the non-standard orthography. The spread of uncountable variations of the meme shows the social process that goes on in the meaning making of the semiotic elements.
