Antioxidant and Antityrosinase Activity of Extract

open access: yesNatural Product Communications, 2013
The effects of Cissus quadrangularis Linn. extract on antioxidation and tyrosinase inhibition were investigated. The extract showed anti-oxidative activity with an IC 50 value of 522.0 μg/mL, and inhibitory effects on tyrosinase activity and melanin ...

The RUNX1b Isoform Defines Hemogenic Competency in Developing Human Endothelial Cells

open access: yesFrontiers in Cell and Developmental Biology, 2021
The transcription factor RUNX1 is a master regulator of blood cell specification. During embryogenesis, hematopoietic progenitors are initially generated from hemogenic endothelium through an endothelium-to-hematopoietic transition controlled by RUNX1 ...

Extramedullary Hematopoiesis Niche in the Spleen [PDF]

open access: yes, 2017
Hematopoiesis is a process in which the Hematopoietic stem cells (HSC’s) differentiate to give rise to all lineages of blood cells. In normal adults, HSC’s reside in the bone marrow (BM) and their cell niche (microenvironment) in the BM is well-studied ...

Lorlatinib‐Containing Therapy for MYCN‐Amplified, ALK‐Mutated Neuroblastoma With Bulky Leptomeningeal Relapse: A Case Report

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Central nervous system (CNS) relapse of neuroblastoma carries a poor prognosis, and craniospinal irradiation (CSI) poses substantial long‐term toxicity in young children. We report a toddler with MYCN‐amplified neuroblastoma harboring somatic ALK R1275Q who developed extensive leptomeningeal relapse with paraplegia.

The role of survivin2 in primitive hematopoiesis during zebrafish development

open access: yes, 2009
Survivin is an inhibitor of apoptosis and its role in embryonic development is not completely understood. In zebrafish, survivin undergoes gene duplication. Survivin1 (sur1) has been shown to mediate angiogenesis but not hematopoiesis.
