Accurate Delivery of Mesenchymal Stem Cell Spheroids With Platelet‐Rich Fibrin Shield: Enhancing Survival and Repair Functions of Sp‐MSCs in Diabetic Wound Healing

Advanced Science, EarlyView.
Autologous plasma‐derived platelet‐rich fibrin (PRF) is prepared as a protective shield for mesenchymal stem cell spheroids (Sp‐MSCs). PRF forms a fibrin shield to protect Sp‐MSCs from the oxidative stress environment. The nutrients in PRF, particularly the α‐granules, can enhance the repair function of Sp‐MSCs.

Asymmetric thymocyte death underlies the CD4:CD8 T-cell ratio in the adaptive immune system [PDF]

, 2013
It has long been recognized that the T-cell compartment has more CD4 helper than CD8 cytotoxic T cells, and this is most evident looking at T-cell development in the thymus.

BCL2-mediated tumorigenicity of a human T-lymphoid cell line: synergy with MYC and inhibition by BCL2 antisense. [PDF]

Proceedings of the National Academy of Sciences, 1990
A gene-transfer approach was used to explore the function of the BCL2 (B-cell lymphoma/leukemia 2) gene in a human T-cell line, Jurkat. Though stable introduction of a BCL2 expression plasmid into Jurkat T cells was by itself insufficient, the combined transfer of BCL2 and MYC genes markedly enhanced the tumorigenicity of these cells in athymic mice ...

Tumor‐Associated Sympathetic Nerves Promote the Progression of Epstein‐Barr Virus‐Positive Diffuse Large B‐Cell Lymphoma

Advanced Science, EarlyView.
Sympathetic nerve innervation promotes the progression of Epstein‐Barr virus‐positive diffuse large B‐cell lymphoma (EBV+ DLBCL) via β2‐adrenergic receptors. The discovery of enhanced nerve infiltration and β2AR expression reveals a novel mechanism and highlights the sympathetic–β2AR axis as a promising target for therapeutic intervention in EBV+ DLBCL.

Heavy metals contaminating the environment of a progressive supranuclear palsy cluster induce tau accumulation and cell death in cultured neurons [PDF]

, 2020
Progressive supranuclear palsy (PSP) is a neurodegenerative disorder characterized by the presence of intracellular aggregates of tau protein and neuronal loss leading to cognitive and motor impairment.

The transcription factor ATF5: role in cellular differentiation, stress responses, and cancer. [PDF]

, 2017
Activating transcription factor 5 (ATF5) is a cellular prosurvival transcription factor within the basic leucine zipper (bZip) family that is involved in cellular differentiation and promotes cellular adaptation to stress.

'Edgetic' perturbation of a C. elegans BCL2 ortholog [PDF]

Nature Methods, 2009
Genes and gene products do not function in isolation but within highly interconnected 'interactome' networks, modeled as graphs of nodes and edges representing macromolecules and interactions between them, respectively. We propose to investigate genotype-phenotype associations by methodical use of alleles that lack single interactions, while retaining ...

Isoquercitrin Alleviates Diabetic Nephropathy by Inhibiting STAT3 Phosphorylation and Dimerization

Advanced Science, EarlyView.
This study identified a natural compound, isoquercitrin, which significantly alleviated kidney inflammation and fibrosis by inhibiting STAT3 activity. Isoquercitrin forms a strong, noncovalent bond that directly binds to STAT3. Isoquercitrin binds to the pY+1 pocket of the SH2 domain of STAT3 via hydrogen bonding with Ser668, Gln635, and Gln633 ...

Effect of Ascorbic Acid on Signaling Pathways of Bcl2 and Bax Genes in AGS Cell Line

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Īlām, 2020
Introduction: Antioxidants have a great influence on the control of oxidative stress and free radicals; moreover, they cause the expression of apoptosis genes. Accordingly, they have an important role in preventing cancer.
