Summary: In this study, an artificial transmembrane signal transduction system using DNA-based artificial membrane receptors is described. Through low pH-mediated formation of the i-motif and dimerization of the receptors, fluorescence resonance energy transfer and G-quadruplex/hemin-mediated fluorescence amplification are activated within giant unilamellar vesicles. The study also establishes an intercellular signal communication model using coacervate microdroplets, which activate the dimerization of artificial receptors and subsequent fluorescence production or polymerization in giant unilamellar vesicles.

Summary: Breast cancer subtypes differ in their treatment and prognosis due to the expression and activity of different receptors. The HER2 subtype has been successfully targeted with anti-HER2 therapies, and this study explores whether the HER2 receptor and downstream signaling network could be potential therapeutic targets beyond the HER2-positive subtype. The findings suggest that major parts of the intracellular signal transduction network are unchanged between subtypes, and alterations in this network could render anti-HER therapies relevant beyond the HER2-positive subtype.

Summary: In this study, we encapsulated Trastuzumab into nanoparticles, referred to as TZPs, using a double emulsion method. Through characterization and experiments, we found that TZPs had higher drug loading and encapsulation efficiency compared to free Trastuzumab, and they could prolong the release of the drug. TZPs exhibited stronger anti-tumor activity in HER2 positive breast cancer cell lines compared to free Trastuzumab. These results suggest that TZPs may have potential advantages in drug delivery in vivo.

Summary: HER-2/neu gene encodes a protein called HER2 that plays an important role in some cancers. This study used the CRISPR/Cas9 method to knockout a potential enhancer called Her2-Enhancer1 located within the HER2 gene, and investigated its regulatory effects on HER2 and HER2-interacting genes. The findings revealed significant alterations in the expression of HER2 and other target genes, as well as an increase in apoptosis rate. These results suggest the potential of this enhancer as a target for therapy in HER2-positive cancers.

Summary: A recent study suggests that HER2-mutated breast cancer may develop resistance to drugs that inhibit the tyrosine kinase domain of HER2 through developing mutations in HER3, which enhance the dimerization between HER2 and HER3. The HER3 mutations augment signaling. This study supports a specific approach to overcoming mutant-HER3-mediated resistance.

Summary: Lysophosphatidic acid receptors (LPARs) play a role in promoting tumorigenesis and therapy resistance in various cancer subtypes. Our study found that increased expression of LPAR1, LPAR4, and LPAR6 correlated with a less aggressive phenotype, while high expression of LPAR2 was associated with increased tumor grade, mutational burden, and decreased survival. Different LPARs were also expressed in different cell types, suggesting potential compensatory signaling in LPAR inhibitor therapy.

Summary: Aging is characterized by chronic low-grade inflammation in multiple tissues, also termed inflammaging, which represents a significant risk factor for many aging-related chronic diseases. However, the mechanisms and regulatory networks underlying inflammaging across different tissues have not yet been fully elucidated. Here, we profiled the transcriptomes and epigenomes of the kidney and liver from young and aged mice and found links between transcriptome changes and chromatin dynamics through integrative analysis. We identified AP-1 and ETS family transcription factors as potential regulators of inflammaging and demonstrated that genetic knockdown of Fos, a major member of the AP-1 family, significantly attenuated the inflammatory response in aged kidneys and livers.

Summary: Biological invasions, especially by Spartina alterniflora, are significantly impacting the structure and functions of coastal ecosystems in China. Urgent efforts to control the spread of this invasive species are hindered by the lack of time-series data. By using satellite images, this study successfully generated annual maps of Spartina saltmarshes from 1985 to 2020, revealing a continuous expansion of Spartina along the coast. The invasion history and frequency of changes were found to be influenced by latitude, with low latitudes experiencing longer and more frequent invasions. Human interventions have contributed to the decline in certain areas, but natural spread remains the primary driver of its extensive invasion.
