Epigenetic control of cell fates is a critical determinant to maintain cell type stability and permit differentiation during embryonic development. However, the epigenetic control mechanisms are not well understood. Here, it is shown that the histone acetyltransferase reader protein BRD8 impairs the conversion of primed mouse EpiSCs (epiblast stem cells) to naive mouse ESCs (embryonic stem cells).

Understanding the nucleation mechanism of peptide self-assembly is fundamental for the design and application of peptide-based materials. To this end, we herein explored the self-assembly processes of three diphenylalanine (FF) derivatives, Boc-XF, Boc-FX, and Boc-FF, where X is p-cyanophenylalanine with the cyano group being an infrared (IR) probe. Using IR probe technique and scanning electron microscopy (SEM), we revealed that the self-assembly of Boc-XF followed a three-step non-classical nucleation mechanism.

With the expansion of floating photovoltaics, rigid connectors offer advantages over polyester ropes by reducing the relative motion of floats and simplifying the layout of the connection system. However, the overall stability and safety of the floating photovoltaic system may be compromised if a wave crest occurs at the connection point of the rigid connector during motion. Furthermore, the rigid connectors with different degrees of freedom significantly impact the motion of the floats and their connection loads.

Ag85B, the primary component of the Ag85 complex and an early secreted protein by Mycobacterium tuberculosis, has shown potential for the treatment of allergic asthma (AA) when used as a Fc-fusion protein. Administered via nasal immunization, Ag85B-Fc fusion protein significantly alleviated airway inflammation and reduced the proportions of some anaphylaxis related cells in lungs, with no significant histopathological injury to major organs in ovalbumin (OVA)-induced AA model mice. To investigate the underlying immune regulatory mechanisms of Ag85B protein, integrated proteomics and transcriptomics analyses were conducted, identifying the complement and coagulation cascades, and phagosomes as the two significantly enriched pathways at both gene and protein levels.

Secretory carrier-associated membrane protein 1 (SCAMP1) is the most universally expressed member of the SCAMP family, and its ability to facilitate endocytosis was demonstrated approximately two decades ago. Nevertheless, its roles in cancer biology are largely unknown, although its expression is significantly increased in most cancer types. Herein, we examined the expression of SCAMP1 in gastric cancer (GC) tissues and found that it was aberrantly increased and positively correlated with tumor size and lymph node metastasis.

The human papillomavirus (HPV) is threatening human health as it spreads globally in varying degrees. On the other hand, the speed and scope of information transmission continues to increase, as well as the significant increase in the number of HPV-related news reports, it has never been more important to explore the role of media news coverage in the spread and control of the virus. Using a decreasing factor that captures the impact of media on the actions of people, this paper develops a model that characterizes the dynamics of HPV transmission with media impact, vaccination and recovery.

As an autoimmune disease, up to 73% of patients with primary biliary cholangitis (PBC) have a combination of extrahepatic autoimmune diseases (EHAIDs); however, the causal relationship between PBC and EHAIDs is unclear. The genome-wide association analyses provided 14 GWAS data for PBC and EHAIDs, and bidirectional, two-sample MR analyses were performed to examine the relationship between PBC and EHAIDs. The analysis using MR provides a strong and meaningful estimation of the bidirectional correlation between PBC and 7 EHAIDs: rheumatoid arthritis, systemic lupus erythematosus, Sjögren's syndrome, systemic sclerosis, autoimmune hypothyroidism, inflammatory bowel disease and ulcerative colitis of its types.
