Mitochondria are organelles that have pivotal functions in producing the energy necessary for life and executing the cell death pathway. Targeting drugs and macromolecules to the mitochondria may provide an effective means of inducing cell death for cancer therapy, and has been actively pursued in the last decade. This review will provide a brief overview of mitochondrial structure and function, how it relates to cancer, and importantly, will discuss different strategies of mitochondrial delivery including delivery using small molecules, peptides, genes encoding proteins and MTSs, and targeting polymers/nanoparticles with payloads to the mitochondria. The advantages and disadvantages for each strategy will be discussed. Specific examples using the latest strategies for mitochondrial targeting will be evaluated, as well as potential opportunities for specific mitochondrial compartment localization, which may lead to improvements in mitochondrial therapeutics. Future perspectives in mitochondrial targeting of drugs and macromolecules will be discussed. Currently this is an under-explored area that is prime for new discoveries in cancer therapeutics.

Electrospinning is a remarkably straightforward and adaptable technique that can be employed to process an array of synthetic and natural materials, resulting in the production of nanoscale fibers. It has emerged as a novel technique for biomedical applications and has gained increasing popularity in the research community in recent times. In the context of tissue repair and tissue engineering, there is a growing tendency toward the integration of biomimetic scaffolds and bioactive macromolecules, particularly proteins and growth factors.

Chemoresistance, a significant challenge in effective cancer treatment needs clear elucidation of the underlying molecular mechanism for the development of novel therapeutic strategies. Alterations in transporter pumps, oncogenes, tumour suppressor genes, mitochondrial function, DNA repair processes, autophagy, epithelial-mesenchymal transition (EMT), cancer stemness, epigenetic modifications, and exosome secretion lead to chemoresistance. Despite notable advancements in targeted cancer therapies employing both small molecules and macromolecules success rates remain suboptimal due to adverse effects like drug efflux, target mutation, increased mortality of normal cells, defective apoptosis, etc.

Cyclic GMP-AMP synthase (cGAS)-Stimulator of interferon genes (STING) signaling pathway, an essential element in the innate antiviral immune responses, has emerged as a key component of innate immune system to modulate type I IFNs production and response by recognizing both exogenous and endogenous DNA. Although some cGAS-STING signaling small molecule agonists have been developed, there are few natural polysaccharides reported to activate cGAS-STING signaling for the treatment of infectious diseases. Here, we reported that Laminaran, a low molecular weight β-glucan storage polysaccharide present in brown algae, potentiates cGAS-STING signaling to promote type I IFNs production and antiviral response.

Transdermal drug delivery (TDD) represents a transformative paradigm in drug administration, offering advantages such as controlled drug release, enhanced patient adherence, and circumvention of hepatic first-pass metabolism. Despite these benefits, the inherent barrier function of the skin, primarily attributed to the stratum corneum, remains a significant impediment to the efficient permeation of therapeutic agents. Recent advancements have focused on macromolecular-assisted permeation enhancers, including carbohydrates, lipids, amino acids, nucleic acids, and cell-penetrating peptides, which modulate skin permeability by transiently altering its structural integrity.

Burns are complex traumatic injuries that lead to severe physical and psychological problems due to the prolonged healing period and resulting physical scars. Owing to their versatility, hydrogels can be loaded with various functional factors, making them promising wound dressings. However, many hydrogel dressings cannot support cell survival for a long time, thereby delaying the process of tissue repair.
