Article Abstract

Low molecular weight fucoidan (LMWF) has been reported to have immunomodulation effects through the increase of the activation and function of macrophages. In this study, the regulating effect of LMWF from grown in New Zealand on dendritic cells (DCs) was investigated. We discovered that LMWF could stimulate DCs' maturation and migration, as well as CD4+ and CD8+ T cells' proliferation in vitro. We proved that this immune promoting activity is activated through TLR4 and its downstream MAPK and NF-κB signaling pathways. Further in vivo (mouse model) investigation showed that LMWF has a strong immunological boosting effect, such as facilitating the proliferation of immune cells and increasing the index of immune organs. These findings suggest that LMWF has a positive immunomodulatory effect and is a promising candidate to supplement cancer immunotherapy.

Background: Rare genetic variation provided by whole genome sequence datasets has been relatively less explored for its contributions to human traits. Meta-analysis of sequencing data offers advantages by integrating larger sample sizes from diverse cohorts, thereby increasing the likelihood of discovering novel insights into complex traits. Furthermore, emerging methods in genome-wide rare variant association testing further improve power and interpretability.

Purpose: Amino acid PET with [F]-fluoroethylthyrosine ([F]FET-PET) is frequently utilized in gliomas. Most studies on prognostication based on amino acid PET comprise mixed cohorts of brain tumors with low- and high-grade features. The objective of this study was to assess the potential prognostic value of [F]FET-PET-based markers in the group of grade 2 adult-type diffuse gliomas, as defined by the WHO CNS 2021 classification.

Structural biology is fundamental to understanding the molecular basis of biological processes. While machine learning-based protein structure prediction has advanced considerably, experimentally determined structures remain indispensable for guiding structure-function analyses and for improving predictive modeling. However, experimental studies of protein complexes continue to pose challenges, particularly due to the necessity of high protein concentrations and purity for downstream analyses such as cryogenic electron microscopy.

A new Escherichia coli laboratory evolution screen for detecting plant ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) mutations with enhanced CO-fixation capacity has identified substitutions that can enhance plant productivity. Selected were a large subunit catalytic (Met-116-Leu) mutation that increases the k of varying plant Rubiscos by 25% to 40% and a solubility (Ala-242-Val) mutation that improves plant Rubisco biogenesis in E. coli 2- to 10-fold.

Ado-trastuzumab is considered a standard treatment for patients with HER2+ metastatic breast cancer (mBC). Current clinical practices do not reliably predict therapeutic outcomes for patients who are refractory to therapy. Long noncoding RNAs (lncRNAs) are emerging as critical regulators of gene expression and therapeutic resistance, and the use of lncRNAs as tumor biomarkers is becoming more common in other diseases.
