Description

The term Tumour Microenvironment (TME) refers to the type of environment that exists around the tumor. Hypoxia, acidosis, fibroblasts, macrophages, increased Interstitial Fluid Pressure (IFP), Extracellular Matrix (ECM), and angiogenesis are a few of the variables that contribute to the development of the TME. The nano formulations enhance drug retention duration and enable drug release at very low doses when combined with anticancer medications. When medicine is administered in modest amounts, it can demonstrate its therapeutic potential efficiently and reduces the likelihood that it will accumulate in other tissues, lowering the likelihood of toxicity. In this study, they examined the findings of previous studies and made an effort to discuss how various nano formulations (nanoparticles, nano emulsions, nano composites, and nano bubbles) work to lessen TME.

The "seed and soil hypothesis" was introduced by Paget in the 1880s. Its goal was to help people comprehend that, in addition to the "seeds," or cancer cells, there is also a need to focus on the "soil," which is in charge of delivering oxygen, vital nutrients, and signals for growth and development. Therefore, tumor proliferation is intricate and varied, and it is regulated by a variety of characteristics in addition to aberrant cells. TME is a heterogenous framework made up of immunological, stromal, pericyte, fibroblast, and endothelial cells, which ultimately results in low oxygen levels, low pH, and increased IFP.

The TME not only contributes significantly to the beginning, growth, and metastasis of tumors but also significantly affects the effectiveness of treatment interventions. Environment-dependent medication issues are the result of on-going interactions between cancer cells and the stroma cells in the area. TME is one of the major obstacles to treating cancer, as is widely documented. One of the most effective ways to get around the barriers to effective cancer treatment is nanotechnology. Numerous studies have been done in different parts of the world to enhance the therapeutic use of anti-cancer medications in TME, focusing on this issue. The broad field of nanotechnology includes nano-delivery systems, also include nano formulations such as nanoparticles, nano bubbles, nano rods, nano fibers, nano capsules, nano composites, or nano hydrogels. Any of the aforementioned delivery methods for anti-cancer medications can significantly enhance their therapeutic effects. For instance, an acidic pH makes TME more severe. This implies that it is necessary to create a pH-responsive nano-delivery technology that can stop drug breakdown at acidic pH and facilitate drug delivery to TME area. The use of a nano-delivery technology not only stops drug deterioration but also helps to reduce side effects and toxicity by using smaller doses.

This study focuses on how the TME affects therapeutic response and discusses how nanotechnology might increase the efficacy of pharmacological treatments by changing TME-related factors. The features of TME and several nano-strategies used to combat TME in various malignancies are highlighted. A significant amount of energy is required for tumor development, but the oxygen supplied by the aberrant tumor vasculature is insufficient, therefore 50-60% of tumors have reduced oxygen levels, also known as hypoxia.

Those quickly replicating cells might survive and thrive in these harsh conditions that are nearly the polar opposite of what is often required to maintain life seems counterintuitive. It became clear after careful examination that cancer cells have developed to endure under these austere conditions. For survival in a hypoxic environment, cancer cells, for instance, can convert from aerobic to anaerobic metabolism. Enzymes from the glycolytic pathway make up many of these targets.

The most popular method of treating cancer and other disorders is nano-delivery systems. In addition to improving targeted drug delivery, drugs encapsulated in nano-delivery systems also reduce toxicity in the body by using lower doses. The use of nanodelivery systems in numerous research undertaken worldwide to treat TME have failed to progress to clinical trials. In this study, they focused on several tumour hallmarks, such as hypoxia, acidosis, IFP, matrix proteins, angiogenesis, fibroblasts, and macrophages, while also discussing the mechanism of innovative nano formulations.
