Secreted frizzled related protein (Sfrp) genes encode extracellular factors that can modulate Wnt signaling. During early post-implantation mouse development Sfrp5 is expressed in the anterior visceral endoderm (AVE) and the ventral foregut endoderm. The AVE is important in anterior–posterior axis formation and the ventral foregut endoderm contributes to multiple gut tissues. Here to determine ...

New techniques based on Exceptional Field Theory have recently allowed for the calculation of Kaluza-Klein spectra certain AdS$_4$ solutions $D=11$ and massive IIA supergravity. These are that consistently uplift $S^7$ $S^6$ from vacua maximal four-dimensional supergravity with SO(8) ISO(7) gaugings. In this paper, we provide complete spectrum five such solutions, all them ${\cal N}=1$. preserv...

Functionally active 70S ribosomes containing 4-thiouridine (s4U) in place of uridine were prepared by a formerly described in vivo substitution method. Proteins were crosslinked to RNA by 366 nm photoactivation of s4U. We observe the systematic and characteristic formation of 30S dimers; they were eliminated for analysis of RNA-protein crosslinks. M13 probes containing rDNA inserts complementar...
