ATF4 Regulates MYB to Increase γ-Globin in Response to Loss of β-Globin

Cell Reports, 2020
Summary: β-Hemoglobinopathies can trigger rapid production of red blood cells in a process known as stress erythropoiesis. Cellular stress prompts differentiating erythroid precursors to express high levels of fetal γ-globin.

Neurotoxic amyloid β‐peptide and tau produce cytokine‐like effects on PMCA in glioblastoma cell lines, enhancing its activity and isoforms expression

FEBS Open Bio, EarlyView.
Two biomarkers of Alzheimer's disease, amyloid β‐peptide (Aβ) and tau, induce the transformation of U‐251 and other glioblastoma cell lines into neurotoxic A1‐like reactive astrocytes. This transformation is produced by cytokines and is followed by upregulation of PMCA activity and isoform expression, and is closely associated with inflammation, as ...

Aberrant splicing of U12-type introns is the hallmark of ZRSR2 mutant myelodysplastic syndrome. [PDF]

, 2015
Somatic mutations in the spliceosome gene ZRSR2-located on the X chromosome-are associated with myelodysplastic syndrome (MDS). ZRSR2 is involved in the recognition of 3'-splice site during the early stages of spliceosome assembly; however, its precise ...

Retrotransposon Expression Is Upregulated in Adulthood and Suppressed during Regeneration of the Limb in the Axolotl (Ambystoma mexicanum)

Advanced Biology, EarlyView.
The axolotl's remarkable regenerative abilities decline with age, the causes may include the numerous repetitive elements within its genome. This study uncovers how Ty3 retrotransposons and coexpression networks involving muscle and immune pathways respond to aging and regeneration, suggesting that transposons respond to physiological shifts and may ...

The Origin of the RNA World: a Kinetic Model [PDF]

arXiv, 1999
The aims of this paper are to propose, construct and analyse microscopic kinetic models for the emergence of long chains of RNA from monomeric beta-D-ribonucleotide precursors in prebiotic circumstances. Our theory starts out from similar but more general chemical assumptions to those of Eigen, namely that catalytic replication can lead to a large ...

Suppression of ILC2 differentiation from committed T cell precursors by E protein transcription factors [PDF]

, 2019
Current models propose that group 2 innate lymphoid cells (ILC2s) are generated in the bone marrow. Here, we demonstrate that subsets of these cells can differentiate from multipotent progenitors and committed T cell precursors in the thymus, both in ...

Developmental Acquisition of Regulomes Underlies Innate Lymphoid Cell Functionality [PDF]

, 2016
Innate lymphoid cells (ILCs) play key roles in host defense, barrier integrity, and homeostasis and mirror adaptive CD4(+) T helper (Th) cell subtypes in both usage of effector molecules and transcription factors.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.
