Curr Opin Biotechnol. 2023 Oct 26;84:103013. doi: 10.1016/j.copbio.2023.103013. Online ahead of print.ABSTRACTPolydopamine (PDA) nanoparticles (NPs) have diverse nanomedicine applications owing to their biocompatibility and abundant entry to cells. Yet, our knowledge in their interactions with cells was infrequently studied until recent years. This review presents the latest insights into the cell-nano interactions of PDA NPs, including their 'self-targeting' to dopamine receptors for cellular entry without the aid of ligands, in vitro 'self-therapeutic' cellular responses (antiferroptosis, macrophage polarization, and mod...

Proline metabolism shapes the tumor microenvironment: from collagen deposition to immune evasion
Curr Opin Biotechnol. 2023 Oct 19;84:103011. doi: 10.1016/j.copbio.2023.103011. Online ahead of print.ABSTRACTProline is a nonessential amino acid, and its metabolism has been implicated in numerous malignancies. Together with a direct role in regulating cancer cells' proliferation and survival, proline metabolism plays active roles in shaping the tumor microenvironment (TME). Cancer-associated fibroblasts (CAFs) display high rates of proline biosynthesis to support the production of collagen for the extracellular matrix (ECM). Indeed, impaired proline metabolism in CAFs results in reduced collagen deposition and compromis...

O-GlcNAcylation at the center of antitumor immunity
Curr Opin Biotechnol. 2023 Oct 18;84:103009. doi: 10.1016/j.copbio.2023.103009. Online ahead of print.ABSTRACTThe post-translational modification known as O-GlcNAcylation is a highly dysregulated process in tumors, and a key contributor to malignant transformation. In contrast, after three decades since its discovery, very little has been revealed about this process in the immune system. With the prospect of targeting O-GlcNAcylation as tumor therapy, greater understanding of how it regulates immune responses in the context of the tumor microenvironment will be needed. Here, we discuss recent discoveries from which a pictu...

Nucleotide metabolism in the regulation of tumor microenvironment and immune cell function
Curr Opin Biotechnol. 2023 Oct 18;84:103008. doi: 10.1016/j.copbio.2023.103008. Online ahead of print.ABSTRACTNucleotide metabolism plays a crucial role in the regulation of the tumor microenvironment (TME) and immune cell function. In the TME, limited availability of nucleotide precursors due to increased consumption by tumor cells and T cells affects both tumor development and immune function. Metabolic reprogramming in tumor cells favors pathways supporting growth and proliferation, including nucleotide synthesis. Additionally, extracellular nucleotides, such as ATP and adenosine, exhibit dual roles in modulating immune...
