The Utilization of Purines and Their Ribosyl Derivatives for the Formation of Adenosine Triphosphate and Guanosine Triphosphate in the Rabbit Reticulocyte

open access: yesJournal of Biological Chemistry, 1966
Abstract The rabbit reticulocyte is capable of utilizing purines and their ribosyl derivatives for nucleoside triphosphate formation. Adenine, adenosine, hypoxanthine, and inosine are used extensively for the synthesis of adenosine triphosphate. Xanthine, guanine, and guanosine are utilized primarily for the synthesis of guanosine triphosphate.

Ferroptosis and Its Emerging Role in Gestational Diabetes Mellitus

open access: yesMedicine Advances, EarlyView.
Ferroptosis contributes to the development of gestational diabetes mellitus (GDM) through iron overload, lipid peroxidation, and antioxidant system disruption. These changes impair adipocyte and β‐cell function, promoting insulin resistance and hyperglycemia.

Anti-cancer Effects of a Chemically Modified miR-143 on Bladder Cancer by Either Systemic or Intravesical Treatment

open access: yesMolecular Therapy: Methods & Clinical Development, 2019
We developed a novel chemically modified miR-143 (miR-143#12), and with it we investigated the contribution of miR-143 to the pathogenesis of bladder cancer (BC), in which miR-143 is extremely downregulated.

Harnessing Phytochemicals for Brain Cancer Therapy: Insights Into Medulloblastoma and Glioblastoma Treatment

open access: yesPhytochemical Analysis, EarlyView.
ABSTRACT Primary brain tumors are life‐threatening diseases. Glioblastoma is the most aggressive type with a poor prognosis. Medulloblastoma is the most common pediatric brain tumor. While surgical treatments often result in recurrences owing to the complex nature of the tumor microenvironment, conventional treatments lower the quality of life of ...
