Background: Alzheimer's disease (AD) is one of the most devastating diseases worldwide. The current drugs for AD can only ameliorate the symptoms rather than reverse or prevent the progress of AD. On the other hand, blood-brain barrier (BBB), as a natural barrier, significantly impedes drug delivery from the blood circulation into the brain. Nanomedicine can be a safe, effective and promising approach to treat AD.
Objective: This review summarizes the recent nanomedicine research in this area, including the use of liposomes and nanoparticles (NPs), to provide new approach for targeted treatment of AD.
Method: Collecting and referring to the related literature in recent 10 years, via searching MeSH Terms "Alzheimer's disease; nanomedicine; nanoparticle; amyloid β peptide; tau protein; autophagy".
Results: Nanomedicines show superiority over conventional anti-AD drugs as a potential weapon against AD by the five proposed mechanisms: many unfavorable pharmaceutical properties of conventional anti-AD drugs maybe greatly overcome by nanomedicine; nanomedicines trigger efficient production of high-titer anti-Aβ antibodies following controlled release of antigens by them; some apolipoprotein- based nanomedicines could preferably bind to Aβ and increase the elimination of Aβ nanomedicine-induced autophagy could be facilitated to increase the elimination of Aβ nanomedicineinduced inhibition of tau aggregation.
Conclusion: Therefore, nanomedicine-mediated drug therapy is promising in the treatment of AD.

The DNA cross-link repair 1B (DCLRE1B) gene is involved in repairing cross-links between DNA strands, including those associated with Hoyeraal-Hreidarsson syndrome and congenital dyskeratosis. However, its role in tumours is not well understood. DCLRE1B expression profiles were examined in tumour tissues and normal tissues using TCGA, GTEx, and TARGET datasets.

P2X7 receptor (P2X7R) plays a role in regulating tumor progression, but it is unclear whether P2X7R affects the pathological characteristics of patients with gastric cancer and the activity of gastric cancer cells. Therefore, this study preliminarily investigated the relationship between P2X7R and clinicopathological features of patients with gastric cancer, and further explored the effect of P2X7R on the proliferation, migration and invasion of gastric cancer cells through functional experiments. The results showed that P2X7R was highly expressed in gastric cancer tissues and gastric cancer cells.

Cuproptosis, a newly identified form of cell death, has drawn increasing attention for its association with various cancers, though its specific role in colorectal cancer (CRC) remains unclear. In this study, transcriptomic and clinical data from CRC patients available in the TCGA database were analyzed to investigate the impact of cuproptosis. Differentially expressed genes linked to cuproptosis were identified using Weighted Gene Co-Expression Network Analysis (WGCNA).

Since designer cells are attracting much attention as a new modality in gene and cell therapy, it would be advantageous to develop synthetic receptors that recognize artificial ligands and activate solely signaling molecules of interest. In this study, we refined the construction of our previously developed minimal engineered receptors (MERs) to avoid off-target activation of STAT5 while maintaining on-target activation of signaling molecules corresponding to tyrosine motifs. Among the myristoylated, cytoplasmic, and transmembrane types of MERs, the cytoplasmic type had the highest signaling efficiency, although there was off-target activation of STAT5 upon ligand stimulation.
