The fos-1 locus encodes 3 transcripts that have some functional variations. fos-1a (syIs123 fos-1a::yfp) is just about exclusively present in the AC and will be the target of hda-1 during AC invasion (Matus et al. 2010). fos-1b(syIs137 KDM1/LSD1 Inhibitor Gene ID fos-1b::cfp) is ERĪ² Agonist MedChemExpress observed at a low level in various uterine cells, which includes the AC (Sherwood et al. 2005), and itdoes not seem to play a function in AC invasion. A different fos-1 transcript, fos-1c, is expressed in uterine p lineage cells and involved in utse formation (Oommen and Newman 2007). We examined syIs123 and syIs137 transgenic animals and discovered that even though fos-1a::yfp was undetectable in vulval cells in the course of the L3 and L4 stages (data not shown), fos-1b::cfp was expressed inside a subset of vulval progeny.n Table 2 Vulval cell fate specification defects in hda-1 RNAi animals Cell Fate Marker zmp-1::gfp ceh-2::gfp egl-17::gfp cdh-3::gfp daf-6::yfp RNAi A L4440 hda-1 L4440 hda-1 L4440 hda-1 L4440 hda-1 L4440 hda-1 one hundred ND one hundred 81 one hundred 60 one hundred 66.six one hundred 60 100 one hundred B1/2 Vulval Cell Variety C one hundred 83.three D one hundred one hundred E one hundred 62.5 F n 50 24 50 27 50 30 50 15 50100 66.six one hundred 76.6100 40 100 83.3Percentage of vulval cells having GFP fluorescence are shown.
