FAM46C and FNDC3A Are Multiple Myeloma Tumor Suppressors That Act in Concert to Impair Clearing of Protein Aggregates and Autophagy.

Multiple myeloma is a plasma cell neoplasm characterized by the production of unfolded immunoglobulins, which cause endoplasmic reticulum (ER) stress and sensitivity to proteasome inhibition. The genomic landscape of multiple myeloma is characterized by the loss of several genes rarely mutated in other cancers that may underline specific weaknesses of multiple myeloma cells. One of these is that is lost in more than 10% of patients with multiple myeloma.

The Plant NF-Y DNA Matrix and .

Nuclear Factor Y (NF-Y) is an evolutionarily conserved trimer formed by a Histone-Fold Domain (HFD) heterodimeric module shared by core histones, and the sequence-specific NF-YA subunit. In plants, the genes encoding each of the three subunits have expanded in number, giving rise to hundreds of potential trimers. While in mammals NF-Y binds a well-characterized motif, with a defined matrix centered on the box, the specificity of the plant trimers has yet to be determined.
