Differentiated cells can be forced to change identity, either to directly adopt another differentiated identity or to revert to a pluripotent state. Direct reprogramming events can also occur naturally. We recently characterized such an event in Caenorhabditis elegans, in which a rectal cell switches to a neuronal cell. Here we have used this single-cell paradigm to investigate the molecular re...
Regulatory programs that control the specification of serotonergic neurons have been investigated by genetic mutant screens in the nematode Caenorhabditis elegans. Loss of a previously uncloned gene, ham-3, affects migration and serotonin antibody staining of the hermaphrodite-specific neuron (HSN) pair. We characterize these defects here in more detail, showing that the defects in serotonin an...
Hydroides elegans is an indirectly developing polychaete with equal spiral cleavage, gastrulation by invagination, and a feeding trochophore. Expression of several transcription factors and differentiation genes has been characterized. Comparative analysis reveals evolutionarily conserved roles. For example, the synexpression of transcription factors FoxA and Brachyury suggests homology of prim...
The streptomycete plasmid SCP2 and its mutant SCP2* (3, 4, 15) are 31-kilobase (kb) (10) sex factors (3) with one to five copies per cell (16). The SCP2 sequence can be stably cloned in Escherichia coli (12). SCP2* is suitable as a cloning vector in streptomycetes (2). Further developments of SCP2* into useful cloning vectors are described in this report. (Portions of this work were presented a...

This study examined Sal-like protein (SALL)1 methylation profiles in head and neck squamous-cell carcinoma (HNSCC) patients at diagnosis and follow-up, and evaluated their prognostic significance and value as a biomarker. SALL1 expression was examined in a panel of cell lines by quantitative reverse transcription PCR (qRT-PCR). Promoter methylation was determined by quantitative methylation-spe...

The kidney, the metanephros, is formed by reciprocal interactions between the metanephric mesenchyme and the ureteric bud, the latter of which is derived from the Wolffian duct that elongates in the rostral-to-caudal direction. Sall1 expressed in the metanephric mesenchyme is essential for ureteric bud attraction in kidney development. Sall4, another member of the Sall gene family, is required ...
Source/Description: A 1.9 Kb Sall-Hindm fragment containing the entire cDNA clone encoding the human liver ACADM gene (1) subcloned into pGEM-3 (Promega Biotec). Polymorphism: This probe identifies a 2-allele BamHI polymorphism with bands at 10 Kb (allele 2) and 5.5 Kb (allele 1): constant bands are present at > 12 Kb, 7 Kb and 2.8 Kb. In addition a 2-allele Msp polymorphism with bands at 10 Kb...
