Impact of cytotoxic chemotherapy on aldo-keto reductase family 1 member B10 expression.

Objective: Aldo-keto reductase family 1 member B10 (AKR1B10) is a protein that is produced and secreted by a significant number of breast cancers. However, a potential confounder to the use of AKR1B10 as a tumor marker is its elevation in patients given cytotoxic chemotherapy. We therefore conducted a prospective study to analyze AKR1B10 levels in patients with breast cancer receiving neoadjuvant cytotoxic chemotherapy.

Exosomal cargos-mediated metabolic reprogramming in tumor microenvironment.

Metabolic reprogramming is one of the hallmarks of cancer. As nutrients are scarce in the tumor microenvironment (TME), tumor cells adopt multiple metabolic adaptations to meet their growth requirements. Metabolic reprogramming is not only present in tumor cells, but exosomal cargos mediates intercellular communication between tumor cells and non-tumor cells in the TME, inducing metabolic remodeling to create an outpost of microvascular enrichment and immune escape.

AKR1B8 deficiency drives severe DSS-induced acute colitis through invasion of luminal bacteria and activation of innate immunity.

Background: Dysfunction of intestinal epithelial cells (IECs) promotes inflammatory bowel disease (IBD) and associated colorectal cancer (CRC). AKR1B8 deficiency impairs the IEC barrier function, leading to susceptibility to chronic colitis induced by dextran sulfate sodium (DSS), yet it remains unclear how acute colitic response is in AKR1B8 deficient mice.

Methods: AKR1B8 knockout (KO) and littermate wild type mice were exposed to oral 1.

Removal of nonspecific binding proteins is required in co-immunoprecipitation with nuclear proteins.

Whether protein samples should be pretreated to remove nonspecific binding proteins in co-immunoprecipitation (CO-IP) is controversial. In this work, nonspecific binding of proteins to agarose beads was found to be greater than that to magnetic beads. The nonspecific binding was increased with the decrease of ion concentrations but reduced by Nonidet P40.

Wnt signaling in triple-negative breast cancers: Its roles in molecular subtyping and cancer cell stemness and its crosstalk with non-coding RNAs.

Triple-negative breast cancers (TNBCs) are now acknowledged as a collection of diseases encompassing distinct histological plasticity, multi-tier molecular heterogeneity, as well as different outcomes. Despite decades of efforts, the molecular subtyping strategy has been theoretical, and target therapies based on molecular alternations barely improve survival rates of TNBC patients, and thus traditional chemotherapy remains the standard of care in clinic. The Wnt signaling is an evolutionarily conserved signaling pathway, playing critical roles in embryogenesis and neoplastic disease.

Differentials of SARS-CoV-2 Viral RNA Re-positivity in Discharged COVID-19 Patients.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly infectious RNA coronavirus responsible for the pandemic of the coronavirus disease 2019 (COVID-19). Recent advances in virology, epidemiology, diagnosis, and clinical management of COVID-19 have contributed to the control and prevention of this disease, but re-positivity of SARS-CoV-2 in recovered COVID-19 patients has brought a new challenge for this worldwide anti-viral battle. Reverse transcription polymerase chain reaction (RT-PCR) tests of the SARS-CoV-2 pathogen is widely used in clinical diagnosis, but a positive RT-PCR result may be multifactorial, including false positive, SARS-CoV-2 RNA fragment shedding, reinfection of SARS-CoV-2, or re-activation of COVID-19.

The functions and mechanisms of prefoldin complex and prefoldin-subunits.

The correct folding is a key process for a protein to acquire its functional structure and conformation. Prefoldin is a well-known chaperone protein that regulates the correct folding of proteins. Prefoldin plays a crucial role in the pathogenesis of common neurodegenerative diseases (Alzheimer's disease, Parkinson's disease, and Huntington's disease).

Exosomal miRNAs in tumor microenvironment.

Tumor microenvironment (TME) is the internal environment in which tumor cells survive, consisting of tumor cells, fibroblasts, endothelial cells, and immune cells, as well as non-cellular components, such as exosomes and cytokines. Exosomes are tiny extracellular vesicles (40-160nm) containing active substances, such as proteins, lipids and nucleic acids. Exosomes carry biologically active miRNAs to shuttle between tumor cells and TME, thereby affecting tumor development.
