Connective Tissue Growth Factor (CCN2/CTGF) and Nephroblastoma Overexpressed (CCN3/NOV) execute key functions within the hematopoietic compartment. Both are abundant in the bone marrow stroma, which is a niche for hematopoiesis and supports marrow function. Roles for 1,25‐dihydroxyvitamin D3 (calcitriol) and all‐trans retinoic acid in the bone marrow have also been elucidated. Interestingly, some of the annotated roles of these vitamins overlap with established functions of CCN2 and CCN3. Yet, no factor has been identified that unifies these observations. In this study, we report the regulation of the CTGF and NOV genes by Myeloid Zinc Finger‐1 (MZF‐1), a hematopoietic transcription factor. We show the interaction of MZF‐1 with the CTGF and NOV promoters in several cell types. Up‐regulation of MZF‐1 via calcitriol and vitamin A induces expression of CTGF and NOV, implicating a role for these vitamins in the functions of these two genes. Lastly, knockdown of MZF1 reduces levels of CTGF and NOV. Collectively, our results argue that MZF‐1 regulates the CTGF and NOV genes in the hematopoietic compartment, and may be involved in their respective functions in the stroma. J. Cell.
