Now, open science company M4K Pharma has taken on development of the ACVR1
inhibitor drugs - with clinical trials on sufferers expected to begin in 2021.
TP-0184 is small molecule inhibitor of ACVR1
, which is involved in the transforming growth factor beta signaling pathway.
This condition is linked to a heterozygous mutation of the Activin A Receptor type 1 (ACVR1
) gene expressing a protein that encodes histidine (H) ratber than arginine (R) at residue 206 (R206H).
gene, also downregulated in differentiated MyoD KO QM7#4 cells, plays an important role in the bone morphogenic protein pathway, which is responsible for the development and repair of the skeletal system .
(b) qRT-PCR analysis of expression levels of lncRNA (PART1) and mRNAs (ACVR1
, E2F3, and VEGFA) in ceRNA network.
A recurrent mutation in the BMP type I receptor ACVR1
causes inherited and sporadic fibrodysplasia ossificans progressiva.
Classical clinical findings are diagnostic and should be made before the appearance of heterotopic bone through genetic analysis of ACVR1

mutations," Journal of Medical Genetics, vol.
Up-regulation of the expression of TGF-[beta] and TGF-[beta] receptors type I and II (ACVR1
and TGFBR2) by NF3 suggests the initiation of the TGF-[beta] signaling pathway.
It is an autosomal dominant trait and affected persons have mutations in the activin A type 1 receptor gene (ACVR1
), chromosomal locus 2q23-24.
In contrast, mRNA levels of interferon gamma receptor 1 (IFNGR1), activin A receptor, type 1 (ACVR1
), and activated leukocyte cell adhesion molecule (ALCAM) all exhibited downregulation in study subjects of the high-level arsenic exposure group.
FOP is caused by a mutation in the gene for ALK2, which is known as ACVR1
, that causes hypersensitivity to certain bone morphogenetic proteins and a neomorphic response to activins.
It is caused by mutations in the ACVR1
gene, which encodes Activin-A receptor type 1, an important protein in the bone morphogenetic protein (BMP) pathway.
Professors Toguchida and Ikeya have been working together to study how the ACVR1
mutation causes FOP and had been focusing on the signalling of Bone Morphogenetic Protein (BMP) until Kyosuke Hino, a visiting scientist from the Sumitomo Dainippon Pharma Corporation, showed that the ACVR1
mutation also activates the signalling of Activin-A.
