Organoid culture media formulated with growth factors of defined cellular activity.

The media formulations necessary for deriving and sustaining organoids from epithelial tissues such as prostate, colon, gastric, liver, pancreas, and others have been established. Critical components of organoid media are a set of growth factors that include R-spondins and BMP signalling antagonists such as Noggin or Gremlin 1. Currently, the practical limitations for formulating organoid media of reproducible potency and larger-scale media production that have hampered further technological applications of organoid technology include: the cost of growth factors such as R-spondins and Gremlin 1/Noggin and their production as defined specific activities free of contaminants that may affect organoid growth.

ADNP Is a Therapeutically Inducible Repressor of WNT Signaling in Colorectal Cancer.

Constitutively active WNT signaling is a hallmark of colorectal cancers and a driver of malignant tumor progression. Therapeutic targeting of WNT signaling is difficult due to high pathway complexity and its role in tissue homeostasis. Here, we identify the transcription factor ADNP as a pharmacologically inducible repressor of WNT signaling in colon cancer.

The extreme Albino3 (Alb3) C terminus is required for Alb3 stability and function in Arabidopsis thaliana.

The extreme Alb3 C terminus is important for Alb3 stability in a light dependent manner, but is dispensable for LHCP insertion or D1 synthesis. YidC/Oxa1/Alb3 dependent insertion of membrane proteins is evolutionary conserved among bacteria, mitochondria and chloroplasts. Chloroplasts are challenged by the need to coordinate membrane integration of nuclear encoded, post-translationally targeted proteins into the thylakoids as well as of proteins translated on plastid ribosomes.
