The Groucho (Gro)/TLE/Grg family of corepressors operates in many signaling pathways (including Notch and Wnt). Gro/TLE proteins recognize a wide range of transcriptional repressors by binding to divergent short peptide sequences, including a C-terminal WRPW/Y motif (Hairy/Hes/Runx) and internal eh1 motifs (FxIxxIL; Engrailed/Goosecoid/Pax/Nkx). Here, we(More)
The Groucho (Gro)/transducin-like enhancer of split family of transcriptional corepressors are implicated in many signalling pathways that are important in development and disease, including those mediated by Notch, Wnt and Hedgehog. Here, we describe a genetic screen in Drosophila that yielded 50 new gro alleles, including the first protein-null allele,(More)
The results are presented of a horizontal epidemiological survey of intestinal infections of children aged between six months and 15 years in three adjacent villages in northern Bangladesh. On the basis of 203 stool sample examinations, the prevalence of Ascaris lumbricoides, Trichuris trichiura, hookworm and amoebic infections was estimated as 68, 56, 53(More)
We have screened chromosome arm 3L for ethyl methanesulfonate-induced mutations that disrupt localization of fluorescently labeled gurken (grk) messenger (m)RNA, whose transport along microtubules establishes both major body axes of the developing Drosophila oocyte. Rapid identification of causative mutations by single-nucleotide polymorphism(More)
The nucleotide sequences of a 3060-bp fragment containing almost the entire coding sequence of one Ascaris suum collagen gene, and a 3019-bp pair fragment containing the 3' end of another A. suum collagen gene have been determined. The polypeptides encoded by these genes show a striking similarity to two Caenorhabditis elegans cuticular collagens, both in(More)
Experimental investigations of the subcutaneous infection of third-stage larvae of Nippostrongylus brasiliensis reveal discrepancies between the actual and intended inoculum, and also variability between replicate inocula. Emphasis is thus placed on the importance of obtaining accurate estimates of the level of confidence associated with inoculum size.(More)
