Roy Morello

Roy Morello, Ph.D., is an Associate Professor in the Department of Physiology and Cell Biology at the University of Arkansas for Medical Sciences (UAMS) College of Medicine, with a secondary appointment in the Division of Genetics, Department of Orthopaedic Surgery. His research focuses on skeletal biology and connective tissue disorders, particularly osteogenesis imperfecta (brittle bone disease), utilizing advanced mouse genetics and molecular techniques to investigate collagen biochemistry and bone development.

Education:

• Ph.D. from University of Brescia

Dr. Morello's laboratory investigates novel genes involved in connective tissue formation and disease, with emphasis on the skeleton. Key contributions include identifying CRTAP as the first gene causing recessive osteogenesis imperfecta and characterizing the Sc65 protein's role in collagen modification. Current projects explore osteocyte function in bone turnover, lung-respiratory defects in OI models, and collagen-modifying proteins in reproductive systems. The lab employs gene targeting, cell biology, and proteomics to elucidate disease mechanisms and identify therapeutic targets.

Analysis of recent publications (2022-2025) reveals a strong trend toward sophisticated conditional mouse models for osteogenesis imperfecta (particularly Col1a1 knock-ins for osteocyte-specific studies), expansion into lung complications and Smith-McCort dysplasia, and investigation of metabolic pathways (NAD salvage) in skeletal development. The research consistently bridges molecular mechanisms with clinical implications across bone, lung, and connective tissue systems.

Scientific Awards:

Dr. Morello currently mentors graduate students and accepts new advisees. His NIH-funded research includes projects on Sc65 and osteocyte-specific RANKL deletion. He maintains extensive collaborations with UAMS bone researchers (Drs. Manolagas, Jilka, Weinstein, O'Brien, Almeida, Zhao, Porter, Iyer, Ambrogini, Ferreira, Xiong) through weekly joint meetings, and collaborates internationally on translational studies. The lab actively participates in grant-funded projects exploring bone-lung interactions and therapeutic targets.

The Morello Lab operates as a multidisciplinary research unit with state-of-the-art facilities for mouse genetics, histology, and molecular analysis. Current projects include multiple OI mouse models, investigations into bone-respiratory system interactions, and characterization of collagen-modifying proteins across tissues. The lab fosters a collaborative environment deeply integrated with the UAMS bone research consortium and clinical departments.
