Hypertrophic scar (HS) is a common fibroproliferative disorders with no fully effective treatments. The conversion of fibroblasts to myofibroblasts is known to play a critical role in HS formation, making it essential to identify molecules that promote myofibroblast dedifferentiation and to elucidate their underlying mechanisms. In this study, we used comparative transcriptomics and single-cell sequencing to identify key molecules and pathways that mediate fibrosis and myofibroblast transdifferentiation.

This study aimed to synthesize a nanocomposite based on tertiary metal oxide FeO@CuO@ZnONPs, starch, ethylcellulose, and collagen, as well as evaluate its biological activities. The prepared nanocomposites were characterized using physicochemical analysis, which included FTIR, XRD, and DLS. Additionally, topographical analysis using FI-SEM, EDX, mapping, HR-TEM, and SAED affirmed the molecular structure and nanosized of formulated nanocomposites.

Ethnopharmacological Relevance: Xinbao pill (XBP) is a renowned Chinese patent medicine, primarily efficacious in warming and nourishing the heart and kidneys, supplementing Qi to boost Yang, and promoting blood circulation to remove blood stasis. XBP has been utilized for the treatment of chronic heart failure (CHF) for nearly 30 years, but the lack of clarity regarding the active ingredients of XBP against CHF has hindered its clinical application and further promotion.
Aim Of The Study: To comprehensively elucidate the efficacy-specific ingredients and potential mechanism of XBP against CHF.

Wound healing is a dynamic process involving multiple cell types and signaling pathways. Dermal sheath cells (DSCs), residing surrounding hair follicles, play a critical role in tissue repair, yet their regulatory mechanisms remain unclear. This study used single-cell proteomics with the mouse model to explore DSC function across different healing stages.

Article Synopsis
- Colorectal cancer (CRC) is a major cause of cancer deaths, and oxaliplatin (OXA) is a primary treatment that faces challenges due to the tumor microenvironment (TME).
- A new multifunctional nanosystem, Rg3-Lip-OXA/CaO, uses Ginsenoside Rg3 liposomes to target CRC cells, delivering OXA and calcium peroxide (CaO) together.
- Research showed that this nanosystem had good stability and release properties, effectively targeted cancer cells, and significantly suppressed tumor growth in mice, while also showing manageable acute toxicity.
