Sophorolipids as anticancer agents: progress and challenges.

Sophorolipids (SLs) are considered effective biosurfactant for cancer treatment, which can efficiently inhibit the viability of various cancer types including breast, lung, liver, cervical and colon cancers. Their mechanism of action targets apoptosis and operates at the level of caspase enzymes, upregulation and downregulation of the B-cell lymphoma (Bcl)-family proteins, and changes in mitochondrial membrane permeability. The binding of SLs to the cancer cell receptors modulates the expression of Bax, APAF1, Bcl-2 and Bcl-x, and triggers the release of cytochrome c into the cytosol which fur

Polyphenols enhance the activity of alkylating agents in leukaemia cell lines.

Polyphenols have been shown to sensitize solid tumours to alkylating agents such as cisplatin, and induce apoptosis and/or cell-cycle arrest. Here, we assess the effects of five polyphenols alone and in combination with three alkylating agents: cisplatin, cyclophosphamide and chlorambucil in lymphoid and myeloid leukaemia cells lines, and non-tumour control cells. In lymphoid leukaemia cell lines there was a synergistic reduction in ATP and glutathione levels, an induction of cell cycle arrest, DNA damage and apoptosis when quercetin, apigenin, emodin and rhein were combined with cisplatin and

Role of mitochondria in physiological activities, diseases, and therapy.

Mitochondria are generally considered essential for life in eukaryotic organisms because they produce most of the energy or adenosine triphosphate (ATP) needed by the cell. Beyond energy production, it is now widely accepted that mitochondria also play a pivotal role in maintaining cellular homeostasis and signaling. The two core processes of mitochondrial dynamics, fission and fusion, serve as crucial foundations for maintaining mitochondrial morphology, distribution, and quantity, thereby ensuring cellular homeostasis. Mitochondrial autophagy (mitophagy) ensures the selective degradation of

The various therapeutic applications of the medical isotope holmium-166: a narrative review.

Over the years, a broad spectrum of applications of the radionuclide holmium-166 as a medical isotope has been established. The isotope holmium-166 is attractive as it emits high-energy beta radiation which can be used for a therapeutic effect and gamma radiation which can be used for nuclear imaging purposes. Furthermore, holmium-165 can be visualized by MRI because of its paramagnetic properties and by CT because of its high density.
