XPO1 regulates erythroid differentiation and is a new target for the treatment of β-thalassemia

Haematologica, 2019
β-thalassemia major (β-TM) is an inherited hemoglobinopathy caused by a quantitative defect in the synthesis of β-globin chains of hemoglobin, leading to the accumulation of free a-globin chains that aggregate and cause ineffective erythropoiesis.

The dynamics of replication licensing in live Caenorhabditis elegans embryos [PDF]

, 2012
Accurate DNA replication requires proper regulation of replication licensing, which entails loading MCM-2-7 onto replication origins. In this paper, we provide the first comprehensive view of replication licensing in vivo, using video microscopy of ...

Innate immunity shapes the persistent transmission of plant viruses by insect vectors

New Plant Protection, EarlyView.
In this review, we focus on two key aspects of the virus–vector interplay: (1) persistently transmitted viruses utilize host factors to overcome transmission barriers; and (2) molecular recognition activates antiviral immunity and subsequent viral counter‐defense. Understanding these interactions offers critical insights for developing novel strategies

Rrp12 and the Exportin Crm1 Participate in Late Assembly Events in the Nucleolus during 40S Ribosomal Subunit Biogenesis [PDF]

, 2016
This is an open-access article distributed under the terms of the Creative Commons Attribution License.During the biogenesis of small ribosomal subunits in eukaryotes, the pre-40S particles formed in the nucleolus are rapidly transported to the cytoplasm.

Benefit of selinexor dose reduction on outcomes with selinexor, bortezomib and dexamethasone in patients with lenalidomide‐refractory multiple myeloma: Subgroup analysis of the BOSTON trial

British Journal of Haematology, EarlyView.
A subgroup analysis of efficacy, safety and QOL in patients who received selinexor in combination with bortezomib and dexamethasone (SVd) with and without selinexor dose reduction and who had lenalidomide‐refractory disease in the phase 3 BOSTON trial showed improvements in efficacy, quality of life (QOL) and safety outcomes with selinexor dose ...

Nullbasic, a potent anti-HIV tat mutant, induces CRM1-dependent disruption of HIV rev trafficking.

PLoS ONE, 2012
Nullbasic, a mutant of the HIV-1 Tat protein, has anti-HIV-1 activity through mechanisms that include inhibition of Rev function and redistribution of the HIV-1 Rev protein from the nucleolus to the nucleoplasm and cytoplasm.

RNA Nuclear Export: From Neurological Disorders to Cancer [PDF]

, 2017
The presence of a nuclear envelope, also known as nuclear membrane, defines the structural framework of all eukaryotic cells by separating the nucleus, which contains the genetic material, from the cytoplasm where the synthesis of proteins takes place ...

Resistance‐exercise‐induced stress intervenes in TGF‐β signaling by cooperatively downregulating nuclear αB‐crystallin and SMAD4 in human skeletal muscle fibers

The FEBS Journal, EarlyView.
Alpha‐crystallin B chain (CRYAB) has been reported to stabilize mothers against decapentaplegic homolog 4 (SMAD4) in transforming growth factor‐β (TGF‐β) signaling, enabling target gene transcription. We show nuclear CRYAB–SMAD4 interaction for the first time in human skeletal muscle fibers and its regulation by exercise.

The nuclear export receptor OsXPO1 is required for rice development and involved in abiotic stress responses

Crop Journal, 2023
The transport of proteins to and from the nucleus is necessary for many cellular processes and is one of the ways plants respond to developmental signals and environmental stresses.
