Protocol to reconstitute translationally arrested heat shock mRNPs and condensates in vitro

open access: yesSTAR Protocols
Summary: Heat shock (HS) coincides with the assembly of translationally arrested heat shock messenger ribonucleoprotein particles (HS-mRNPs) and condensates. Here, we present a protocol to reconstitute HS-mRNPs and HS condensates with eIF4G, eIF4E, Pab1p,

A Mammalian Expression Vector for Expression and Purification of Secreted Proteins for Structural Studies

open access: yesProtein Expression and Purification, 2000
A mammalian expression vector with features optimized for simple expression and purification of secreted proteins has been developed. This vector was constructed to facilitate X-ray crystallographic studies of cysteine-rich glycoproteins that are difficult to express by other means. Proteins expressed with this vector possess an N-terminal human growth

Soluble expression and partial purification of recombinant human erythropoietin from E. coli

open access: yes, 2014
Human erythropoietin (hEpo) is an essential regulator of erythrocyte production that induces the division and differentiation of erythroid progenitor cells in the bone marrow into mature erythrocytes.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Protocol for measuring β-arrestin1-phosphorylated peptide interaction and analyzing conformational dynamics of β-arrestin1

open access: yesSTAR Protocols
Summary: Arrestins associate with phosphorylated G protein-coupled receptors and undergo conformational changes. Here, we present a protocol for measuring β-arrestin1-phosphorylated peptide interaction and analyzing conformational dynamics of β-arrestin1.

Expression, purification and characterisation of GIGANTEA: A circadian clock-controlled regulator of photoperiodic flowering in plants

open access: yes, 2010
The Arabidopsis thaliana (Arabidopsis) GIGANTEA (GI) gene is a central component of the photoperiodic flowering pathway. While it has been 40 years since the first mutant alleles of GI were described much is still unknown about the molecular mechanism of

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

High-level expression, purification, and crystallization of recombinant rat leukotriene C4 synthase from the yeast Pichia pastoris

open access: yes, 2008
Leukotriene C(4) synthase (LTC4S) is a member of the MAPEG family of integral membrane proteins and catalyzes the conjugation of leukotriene A(4) with glutathione to form leukotriene C(4), a powerful mediator of allergic inflammation and anaphylaxis ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Expression, purification, and functional characterization of a stable helicase domain from a tomato mosaic virus replication protein.

open access: yes, 2012
Tomato mosaic virus (genus, Tobamovirus) is a member of the alphavirus-like superfamily of positive-strand RNA viruses, which include many plant and animal viruses of agronomical and clinical importance.
