To date, treatments of Osteoarthritis are not able to provide the pathology regression. In vitro models are therefore necessary to: i) investigate the mechanisms involved in the disease evolution, ii) identify pharmacological targets, and iii) perform predictive tests for new drug delivery strategies.

Calcific aortic valve disease (CAVD) is the most prevalent valvular heart disease. Valve interstitial cells (VICs) mediate calcification in the aortic valve (AV) leaflets, leading to aortic stenosis (AS) and eventually heart failure. Aortic valve replacement (AVR) surgery is the only available treatment. Drug-based therapies and the in vitro models to study CAVD are inadequate or lacking. Here, we present a forward-looking review of 3D CAVD models, miRNA-based therapeutics and controlled drug-delivery strategies.

A drug delivery system is a system in which a drug is released from a pharmaceutical dosage form to achieve the desired pharmacological effect. The system consists of conventional and new drug delivery systems. In the new drug delivery system, polymers are used as a matrix. The aim of this article is to find out and understand the formulation and evaluation of natural ingredients that have anticancer activity with different dosage forms and the basis for developing these dosages. Journal searches in this review came from primary data sources on the internet. Journal searches were carried out using a search engine such as Google Scholar, PubMed, and ScienceDirect. In recent years, natural products, such as extract, fraction, and isolate, are getting attention to help treat cancer. Because of their low solubility and bioavailability, the effectiveness tends to be lower than synthetic drugs. Therefore, a dosage form with a new drug delivery system was made to overcome the problem. The dosage forms commonly made are patch, suspension, powder, and emulsion with a new drug delivery system. To ensure the product that has been made met the requirements, they need to be evaluated with various methods like In vitro Study, morphology study, particle size study, and others. Cancer treatment using the natural product can be delivered through several dosage forms like patch, suspension, powder, and emulsion, with specific formulation and manufacturing methods based on several considerations such as natural ingredients properties, dosage form selection, excipient properties, and the purpose of the formulation. Dosage forms that has been made are then evaluated using several evaluation methods.

Cancer, a complex series of diseased conditions, contributes to a significant health problem and is a leading cause of mortalities across the world. Lately, with the advent of improved diagnostics and imaging techniques, and newer advanced oral chemotherapeutics; millions of cancer affected people can lengthen their life span. Despite all the challenges associated with an active chemotherapeutic molecule like microenvironment and the intestinal barrier of the gastrointestinal tract (GIT) etc., the oral delivery remains the most acceptable route of drug administration. In this regard, nanotechnology has played a significant role in the counteracting the challenges encountered with newly developed molecules and aiding in improving their bioavailability and targetability to the tumour site, while administering through the oral route. Several literature instances document the usage of nanostructured drug delivery systems such as lipid-based, polymerbased or metallic nanomaterials to improve the efficacy of chemotherapy. Besides, sitespecific targeted surface-modified drug delivery system designed to deliver the active molecule has opened up to the newer avenues of nanotechnology. However, the issue of potential toxicity allied with nanotechnology cannot be compromised and thus, needs specific ethical regulations and guidelines. The various in vitro models have been developed to evaluate the in vitro toxicity profile which can be further correlated with the invivo model. Thus, this review provides a summarized account of the various aspects related to the role of nanotechnology in cancer therapy and various related issues thereof; that must be triumphed over to apprehend its full promise.

Stimuli-responsive drug-delivery systems (DDSs) have emerged as a potential tool for applications in healthcare, mainly in the treatment of cancer where versatile nanocarriers are co-triggered by endogenous and exogenous stimuli. Two-dimensional (2D) cell cultures are the most important in vitro model used to evaluate the anticancer activity of these stimuli-responsive DDSs due to their easy manipulation and versatility. However, some limitations suggest that these in vitro models poorly predict the outcome of in vivo studies. One of the main drawbacks of 2D cell cultures is their inadequate representation of the 3D environment’s physiological complexity, which sees cells interact with each other and the extracellular matrix (ECM) according to their specific cellular organization. In this regard, 3D cancer models are a promising approach that can overcome the main shortcomings of 2D cancer cell cultures, as these in vitro models possess many peculiarities by which they mimic in vivo tumors, including physiologically relevant cell–cell and cell–ECM interactions. This is, in our opinion, even more relevant when a stimuli-responsive DDS is being investigated. In this review, we therefore report and discuss endogenous and exogenous stimuli-responsive DDSs whose effectiveness has been tested using 3D cancer cell cultures.
