Development of pH-responsive porphyran-coated gold nanorods for tumor photothermal and immunotherapy.

Cancer poses a significant threat to human health, and monotherapy frequently fails to achieve optimal therapeutic outcomes. Based on this premise, porphyran (PHP), a marine polysaccharide with immunomodulatory function, was used as a framework to coat gold nanorods and construct a novel nanomedicine (PHP-MPBA-GNRs) combining photothermal therapy and immunotherapy. In this design, PHP not only maintained the dispersion stability and photothermal stability of gold nanorods but also could be released under weakly acidic conditions to activate anti-tumor immunity.

A fungal polysaccharide from Fomitopsis officinalis as a multi-target molecule to combat cancer.

Some macrofungi have a long history of being used as traditional or folk medicines, making significant contributions to human health. To discover bioactive molecules with potential anticancer properties, a homogeneous heteropolysaccharide (FOBP90-1) was purified from the medicinal macrofungus Fomitopsis officinalis. FOBP90-1 was found to have a molecular weight of 2.

Overview of Medicinally Important Diterpenoids Derived from Plastids.

Background: FL 32608 Terpenoids are hydrocarbon compounds derived from common fivecarbon isoprene (C5H8) building blocks. They are formed through the condensation and subsequent modification of isoprene units in various ways including - among others - cyclization and/or oxygenation. Their synthesis is localized either to the chloroplast and/or to the cytoplasm/peroxisome/ endoplasmic reticulum and mitochondrion.

Genome-wide analysis and molecular dissection of the SPL gene family in Salvia miltiorrhiza.

SQUAMOSA promoter binding protein-likes (SPLs) are plant-specific transcription factors playing vital regulatory roles in plant growth and development. There is no information about SPLs in Salvia miltiorrhiza (Danshen), a significant medicinal plant widely used in Traditional Chinese medicine (TCM) for >1,700 years and an emerging model plant for TCM studies. Through genome-wide identification and subsequent molecular cloning, we identified a total 15 SmSPLs with divergent sequence features, gene structures, and motifs.
