The Role of the Ubiquitin System in Eye Diseases.

The ubiquitin-proteasome system (UPS) is a fundamental process that regulates various biological functions, including immune response, cell cycle, oxidative stress, migration, and cellular proliferation. This system is responsible for the degradation of proteins, while proteasomes play a significant role in mechanisms involved in health and human diseases. The participation of the UPS in immune response is particularly relevant, leading to the involvement of immunoproteasomes. This specialized proteasome is involved in the processing and presentation of antigenic peptides, making it crucial fo

Natural products targeting ferroptosis in cancer: molecular mechanisms and applications.

Ferroptosis is a novel class of programmed cell death that is mainly dependent on intracellular iron accumulation and lipid peroxidation. Ferroptosis is closely related to a variety of human diseases, especially different kinds of cancer. Several small molecule inducers have been developed to induce ferroptosis in tumor cells, some of which have been used in clinical studies. However, these chemical small molecules have toxic effects that limit its wide application. Natural products, however, have a natural advantage in cancer therapy due to their low toxicity and side effects. Some natural pr

Prevention of Anthracycline-Induced Cardiotoxicity: The Good and Bad of Current and Alternative Therapies.

Doxorubicin (Dox)-induced cardiotoxicity (DIC) remains a serious health burden, especially in developing countries. Unfortunately, the high cost of current preventative strategies has marginalized numerous cancer patients because of socio-economic factors. In addition, the efficacy of these strategies, without reducing the chemotherapeutic properties of Dox, is frequently questioned. These limitations have widened the gap and necessity for alternative medicines, like flavonoids, to be investigated. However, new therapeutics may also present their own shortcomings, ruling out the idea of "natur

Chondroprotection and Molecular Mechanism of Action of Phytonutraceuticals on Osteoarthritis.

Osteoarthritis (OA) is a degenerative joint disease and an important cause of incapacitation. There is a lack of drugs and effective treatments that stop or slow the OA progression. Modern pharmacological treatments, such as analgesics, have analgesic effects but do not affect the course of OA. Long-term use of these drugs can lead to serious side effects. Given the OA nature, it is likely that lifelong treatment will be required to stop or slow its progression. Therefore, there is an urgent need for disease-modifying OA treatments that are also safe for clinical use over long periods. Phytonu

The role of heat shock protein 90 in idiopathic pulmonary fibrosis: state of the art.
