Microbial cell factories have shown great potential for industrial production with the benefit of being environmentally friendly and sustainable. is a promising and superior non-model host for biomanufacturing due to its cumulated advantages compared to model microorganisms, such as high fluxes of metabolic precursors (acetyl-CoA and malonyl-CoA) and its naturally hydrophobic microenvironment. However, although diverse compounds have been synthesized in cell factories, most of the relevant studies have not reached the level of industrialization and commercialization due to a number of remaining challenges, including unbalanced metabolic flux, conflict between cell growth and product synthesis, and cytotoxic effects. Here, various metabolic engineering strategies for solving the challenges are summarized, which is developing fast and extremely conducive to rational design and reconstruction of robust cell factories for advanced biomanufacturing. Finally, future engineering efforts for enhancing the production efficiency of this platform strain are highlighted.

Recently, a variety of stimulus-responsive hydrogel platforms have been developed, specifically designed to respond to changes in physiological signals within the disease microenvironment. However, due to the restricted regulation of drug release behavior in vivo by such hydrogel systems, the precise control of drug release kinetics has not been achieved. Therefore, developing precise drug delivery platforms that enable programmable and "on-off" delivery remains a challenge in this field.

Chemotherapy is often hindered by systemic toxicity and poor selectivity. To address these issues, we develop an enzyme-responsive metallopeptide hydrogel (HY-Pd) that integrates enzyme-instructed self-assembly (EISA) and bioorthogonal catalysis for selective tumor-targeted prodrug activation. Upon exposure to alkaline phosphatase (ALP), which is overexpressed in osteosarcoma cells (Saos-2), HY-Pd selectively accumulates and self-assembles into catalytic nanofibers.

Aim: To critically review the emerging evidence from two randomised trials-KEYNOTE-689 and NIVOPOSTOP-on perioperative immune checkpoint inhibition in resectable, locally advanced head and neck squamous cell carcinoma, and to elucidate how these positive results may redefine the current and future treatment paradigms.
Methods: We conducted a narrative review comparing the design, patient populations, treatment protocols, and outcomes of KEYNOTE-689 and NIVOPOSTOP. Data sources included ClinicalTrials.

The booming field of synthetic biology and metabolic engineering provides promising approaches for sustainable manufacturing of chemicals from renewable feedstocks with microbial cell factories. Classical metabolic engineering strategies mainly focus on altering gene expression levels and enzyme concentrations to improve the metabolic fluxes of specific pathways. However, the impact and limitations of enzyme properties, which are usually ignored in classical metabolic engineering efforts, can hinder further optimization of microbial cell factories.

This study aimed to evaluate the optimal nitrogen source for the production of antioxidant exopolysaccharides (EPSs) by KW8 using cassava pulp carbon source. Various nitrogen sources were initially screened, and yeast extract was identified as the most effective. Further optimization was conducted using Response Surface Methodology (RSM) with a Central Composite Design (CCD) to assess the influence of key parameters, including pH, inoculum size, carbon-to-nitrogen (C/N) ratio, and agitation speed on EPS production.
