EXPRESSION AND SUBCELLULAR LOCALIZATION OF JAB1 AND P27

Lee S., Ahn J., Chung Y.J. Internal medicine, Chung-Ang University Hospital, Seoul, Korea Abstract Down-regulation of p27Kip1, which is well-known cell cycle inhibitor, is associated with advanced stage of cancer and poor patient survival. However, recent studies show that cytoplasmic localization of p27Kip1 would be more meaningful rather than expression levels in terms of cancer Read More

FATE MAPPING REVEAL THAT MIDLINE THYROID PROGENITORS ARISE FROM SONIC HEDGEHOG (SHH) NEGATIVE FOREGUT ENDODERM BUT SHH POSITIVE CELLS ENTER THE THYROID VIA THE PHARYNGEAL POUCHES

Nilsson M., Westerlund J., Fagman H. Department of Medical Chemistry and Cell Biology, Institute of Biomedicine, Sahlgrenska Academy, Göteborg University, Göteborg, Sweden Abstract The thyroid develops from distinct regions in the foregut endoderm, the midline and lateral primordia.
