The Role Of Gdf5 In Regulating Enthesopathy Development In The Hyp Mouse Model Of Xlh, Melissa Sorsby, Shaza Almardini, Ahmad Alayyat, Ashleigh Hughes, Shreya Venkat, Mansoor Rahman, Jiana Baker, Rakshya Rana, Vicki Rosen, Eva S Liu

Staff and Researcher Publications

X-linked hypophosphatemia (XLH) is caused by mutations in PHEX, leading to rickets and osteomalacia. Adults affected with XLH develop a mineralization of the bone-tendon attachment site (enthesis), called enthesopathy, which causes significant pain and impaired movement. Entheses in mice with XLH (Hyp) have enhanced bone morphogenetic protein (BMP) and Indian hedgehog (IHH) signaling. Treatment of Hyp mice with the BMP signaling blocker palovarotene attenuated BMP/IHH signaling in Hyp entheses, thus indicating that BMP signaling plays a pathogenic role in enthesopathy development and that IHH signaling is activated by BMP signaling in entheses. It was previously shown that mRNA expression of …

Using Deepsignalingflow To Mine Signaling Flows Interpreting Mechanism Of Synergy Of Cocktails, Heming Zhang, Yixin Chen, Philip Payne, Fuhai Li

2020-Current year OA Pubs

Complex signaling pathways are believed to be responsible for drug resistance. Drug combinations perturbing multiple signaling targets have the potential to reduce drug resistance. The large-scale multi-omic datasets and experimental drug combination synergistic score data are valuable resources to study mechanisms of synergy (MoS) to guide the development of precision drug combinations. However, signaling patterns of MoS are complex and remain unclear, and thus it is challenging to identify synergistic drug combinations in clinical. Herein, we proposed a novel integrative and interpretable graph AI model, DeepSignalingFlow, to uncover the MoS by integrating and mining multi-omic data. The major innovation is …

Preparation Of A Chiral Hyperbranched Polymer Based On Cinchona Alkaloids And Investigation Of Its Catalytic Activity In Asymmetric Reactions, Rafiqul Islam, Mohammad Shahid Ullah, Abdus Salam, Shinichi Itsuno

Turkish Journal of Chemistry

Cinchona alkaloid-derived sulfonamides and ester dimers containing chiral hyperbranched polymers have been successfully synthesized and applied as catalysts in asymmetric reactions. Several hyperbranched polymers derived from cinchona alkaloids, incorporating sulfonamides and esters, were synthesized through Mizoroki–Heck coupling polymerization. These polymers were subsequently applied in enantioselective Michael addition reactions. As the prepared polymers are not soluble in frequently used organic solvents, they act as efficient catalysts in the enantioselective reaction of β-ketoesters to nitroolefins, achieving up to 99% enantioselectivity with good yields. The insoluble property allows them to better satisfy “green chemistry” requirements and be used several times without losing the …
