Epigenetic and Metabolic Regulation of Macrophages during Gout
Metabolites are the substrate, intermediate, or final products of metabolic reactions that drive the function of a given cell in a particular time and context. Therefore, metabolites provide essential information about the connection between gene expression and the environment, and, as such, they are elegant disease biomarkers. Macrophages represent an elegant model for understanding histone dynamics, transcription factor recruitment, and changes in gene expression during signal transduction by environmental signals.

Klotho and Mesenchymal Stem Cells
Chronic kidney disease (CKD) and acute kidney injury (AKI) are public health problems, and their prevalence rates have increased with the aging of the population. They are associated with the presence of comorbidities, in particular diabetes mellitus and hypertension, resulting in a high financial burden for the health system. Studies have indicated Klotho as a promising therapeutic approach for these conditions. Klotho reduces inflammation, oxidative stress and fibrosis and counter-regulates the renin-angiotensin-aldosterone system. In CKD and AKI, Klotho expression is downregulated from early stages and correlates with disease progression. Therefore, the restoration of its levels, through exogenous or endogenous pathways, has renoprotective effects. An important strategy for administering Klotho is through mesenchymal stem cells (MSCs).

Crucial Mediators of Adipocyte Intercellular Communication
Cancer research has prioritized the study of the tumor microenvironment (TME) as a crucial area of investigation. Understanding the communication between tumor cells and the various cell types within the TME has become a focal point. Bidirectional communication processes between these cells support cellular transformation, as well as the survival, invasion, and metastatic dissemination of tumor cells. Extracellular vesicles are lipid bilayer structures secreted by cells that emerge as important mediators of this cell-to-cell communication. EVs transfer their molecular cargo, including proteins and nucleic acids, and particularly microRNAs, which play critical roles in intercellular communication. Adipocytes, a significant component of the breast stroma, exhibit high EV secretory activity, which can then modulate metabolic processes, promoting the growth, proliferation, and migration of tumor cells.

3D Cell Culture in Brief
Three-dimensional (3D) cell culture represents a paradigm shift in cellular research. Unlike traditional two-dimensional (2D) cultures, it offers a more physiologically relevant environment for studying cells and tissues. In 3D culture, cells grow within complex three-dimensional structures that mimic the architecture of living organs and tissues. This approach allows researchers to explore cell behavior, disease mechanisms, and drug responses with greater accuracy. Methods like hydrogels, spheroids, and bioprinting enable the creation of 3D models that faithfully replicate in vivo conditions. These models find applications in diverse fields, including cancer research, neuroscience, infectious diseases, drug development, and tissue engineering. By improving disease modeling, drug screening, and tissue regeneration, 3D cell culture is driving advancements in biomedical research and offering new avenues for understanding and treating diseases. While challenges remain, ongoing innovations in 3D culture techniques are poised to reshape the landscape of cellular research.

Versatile Attributes of MGMT
O6-methylguanine-DNA methyltransferase (MGMT or AGT) is a DNA repair protein with the capability to remove alkyl groups from O6-AlkylG adducts. Moreover, MGMT plays a crucial role in repairing DNA damage induced by methylating agents like temozolomide and chloroethylating agents such as carmustine, and thereby contributes to chemotherapeutic resistance when these agents are used.

Cadmium-Associated Molecular Signatures in Cancer Cell Models
The exposure of cancer cells to cadmium and its compounds is often associated with the development of more malignant phenotypes, thereby contributing to the acceleration of tumor progression. It is known that cadmium is a transcriptional regulator that induces molecular reprogramming, and therefore the study of differentially expressed genes has enabled the identification and classification of molecular signatures inherent in human neoplastic cells upon cadmium exposure as useful biomarkers that are potentially transferable to clinical research.

Cancer Metastasis from Physical Perspective
Tumor diseases become a huge problem when they embark on a path that advances to malignancy, such as the process of metastasis. Cancer metastasis has been thoroughly investigated from a biological perspective in the past, whereas it has still been less explored from a physical perspective. Until now, the intraluminal pathway of cancer metastasis has received the most attention, while the interaction of cancer cells with macrophages has received little attention. Apart from the biochemical characteristics, tumor treatments also rely on the tumor microenvironment, which is recognized to be immunosuppressive and, as has recently been found, mechanically stimulates cancer cells and thus alters their functions.

Cells Respond to Mechanical Cues of Extracellular Matrix
Extracellular biophysical properties have particular implications for a wide spectrum of cellular behaviors and functions, including growth, motility, differentiation, apoptosis, gene expression, cell–matrix and cell–cell adhesion, and signal transduction including mechanotransduction. Cells not only react to unambiguously mechanical cues from the extracellular matrix (ECM), but can occasionally manipulate the mechanical features of the matrix in parallel with biological characteristics, thus interfering with downstream matrix-based cues in both physiological and pathological processes. Bidirectional interactions between cells and (bio)materials in vitro can alter cell phenotype and mechanotransduction, as well as ECM structure, intentionally or unintentionally. Interactions between cell and matrix mechanics in vivo are of particular importance in a variety of diseases, including primarily cancer.

Tumor Angiogenesis and Vasculogenesis
Cancer cells exploit blood vessels to survive and diffuse in the body, metastasizing distant organs. During tumor expansion, the neoplastic mass progressively induces modifications in the microenvironment due to its uncontrolled growth, generating a hypoxic and low pH milieu with high fluid pressure and low nutrient concentration.

Environmental Determinants of Ferroptosis in Cancer
Many metastasizing cancer cells are vulnerable to a particular type of cell death known as ferroptosis, which is an iron-dependent form of cell death caused by accumulative oxidative stress. Interestingly, many intracellular and extracellular factors can influence ferroptosis and, therefore, dictate the efficiency and route of tumor metastasis.
