Metabolic reprogramming in cancer cells involves changes in glucose metabolism, glutamine utilization, and lipid production, as well as promoting increased cell proliferation, survival, and immune resistance by altering the tumor microenvironment. Our study analyzes metabolic reprogramming in neoplastically transformed cells, focusing on changes in glucose metabolism, glutaminolysis, and lipid synthesis. Moreover, we discuss the therapeutic potential of targeting cancer metabolism, focusing on key enzymes involved in glycolysis, the pentose phosphate pathway, and amino acid metabolism, including lactate dehydrogenase A, hexokinase, phosphofructokinase and others. The review also highlights challenges such as metabolic heterogeneity, adaptability, and the need for personalized therapies to overcome resistance and minimize adverse effects in cancer treatment. This review underscores the significance of comprehending metabolic reprogramming in cancer cells to engineer targeted therapies, personalize treatment methodologies, and surmount challenges, including metabolic plasticity and therapeutic resistance.

The liver is one of the most common sites for metastasis, which involves the spread from primary tumors to surrounding organs and tissues in the human body. There are a few steps in cancer expansion: invasion, inflammatory processes allowing the hepatic niche to be created, adhesions to ECM, neovascularization, and secretion of enzymes. The spread of tumor cells depends on the microenvironment created by the contribution of many biomolecules, including proteolytic enzymes, cytokines, growth factors, and cell adhesion molecules that enable tumor cells to interact with the microenvironment. Moreover, the microenvironment plays a significant role in tumor growth and expansion. The secreted enzymes help cancer cells facilitate newly formed hepatic niches and promote migration and invasion. Our study discusses pharmacological methods used to prevent liver metastasis by targeting the tumor microenvironment and cancer cell colonization in the liver. We examine randomized studies focusing on median survival duration and median overall survival in patients administered placebo compared with those treated with bevacizumab, ramucirumab, regorafenib, and ziv-aflibercept in addition to current chemotherapy. We also include research on mice and their responses to these medications, which may suppress metastasis progression. Finally, we discuss the significance of non-pharmacological methods, including surgical procedures, radiotherapy, cryotherapy, radiofrequency ablation (RFA), and transarterial embolization (TAE). In conclusion, the given methods can successfully prevent metastases to the liver and prolong the median survival duration and median overall survival in patients suffering from cancer.

Lipid peroxidation (LPO) is a process where polyunsaturated fatty acids (PUFA) in cellular membranes are oxidized. This process is mediated by reactive oxygen species (ROS) and leads to the formation of reactive products, including 4-hydroxynonenal (4-HNE), malondialdehyde (MDA), and oxidized phospholipids. At low concentrations these products act as second messengers in adaptive redox signalling and metabolic homeostasis, whereas at higher concentrations they compromise membrane integrity and promote cell death. Lipid peroxidation plays a crucial role in anticancer therapies. Here we focus on three mechanistically complementary drugs—sorafenib, cisplatin, and olaparib—because each converges, directly or indirectly, on the redox/LPO axis (system xc−/GPX4 modulation, mitochondrial ROS, and SLC7A11 regulation, respectively), modulating tumor cell responses by inducing PUFA oxidation, mitochondrial dysfunction, and membrane damage. However, tumor cells have several protective pathways against oxidative stress, such as increased expression of glutathione peroxidase 4 (GPX4), the SLC7A11 system Xc, and detoxification of reactive aldehydes. Enrichment of membranes with PUFA increases susceptibility to lipid peroxidation and ferroptosis, thereby sensitizing tumor cells to therapy, whereas enrichment with monounsaturated fatty acids (MUFA), driven by the SREBP1–SCD1 axis, limits peroxidation and confers resistance. Among regulated cell death modalities, ferroptosis is strictly dependent on lipid peroxidation, whereas apoptosis, necrosis, necroptosis, pyroptosis, and immunogenic cell death can be modulated by lipid peroxidation but do not universally require it. Collectively, these mechanisms indicate that lipid peroxidation is an important—though not exclusive—determinant of anticancer drug sensitivity and resistance, and that its dual, context-dependent role (tumor-suppressive at high flux, tumor-promoting under chronic, sub-lethal exposure) must be considered when designing LPO-based therapeutic strategies.

Herbs from the Gentianaceae family are widely known for their medicinal and pharmacological properties. They were used centuries ago as a part of traditional medicine in China and Tibet. This review aims to draw attention to the potential uses of gentian herbs in treating various diseases, including skin conditions, gastrointestinal and liver disorders, wound healing, rheumatoid arthritis, and diabetes. The aim of our study was to systematically summarize current knowledge about key bioactive compounds present in both roots and aerial parts—such as xanthones, iridoids, and flavonoids—and highlight their pharmacological significance. We also focused on the Gentianaceae family’s usage in complementary and alternative medicine, as well as their anti-inflammatory, anti-melanogenic, anti-ischemic, anti-fibrotic, and antioxidant properties, which can be utilized in the treatment and prevention of dermatological diseases, such as skin cancers. Here, we involve ethnomedicinal knowledge with modern pharmacological data; we also highlight the scientific relevance of gentian-derived compounds in drug development. This review concludes that these species represent a promising source of natural agents, while also underlining the need for further research and conservation strategies to preserve threatened species.

Cross-reactivity among nonsteroidal anti-inflammatory drugs (NSAIDs) creates a significant clinical difficulty, especially in patients with NSAID hypersensitivity. These reactions are based on cyclooxygenase-1 (COX-1) inhibition and non-immunoglobulin E (IgE)-mediated reactions. COX-1 inhibition leads to dysregulation of arachidonic acid metabolism, with decreased prostaglandin synthesis and increased leukotriene production. Clinically, cross-intolerant reactions manifest in different phenotypes, including NSAID-exacerbated respiratory disease (NERD), NSAID-induced urticaria/angioedema (NIUA), and NSAID-exacerbated cutaneous disease (NECD). In contrast, true allergic reactions—such as single-NSAID-induced urticaria/angioedema and anaphylaxis (SNIUAA) and single-NSAID-induced delayed hypersensitivity reactions (SNIDHR)—are immunologically mediated and drug-specific. These phenotypes differ in underlying conditions, clinical manifestations, and patterns of NSAID tolerance. Paracetamol is generally considered a safer alternative due to its weak COX-1 inhibition; however, reactions may still occur, particularly at higher doses. Selective COX-2 inhibitors are usually better tolerated, however their safety should be confirmed, preferably through controlled drug provocation testing due to sporadic reactions in cross-intolerant patients. Understanding the distinction between pharmacologically mediated cross-intolerance and true allergic reactions is essential for accurate diagnosis, risk stratification, and therapeutic decision-making. This review summarizes current evidence on the mechanisms underlying NSAID hypersensitivity, analyzes the tolerability of paracetamol and alternative analgesics, and discusses practical management strategies to reduce the risk of adverse reactions.

People affected by diabetes mellitus (DM), chronic kidney disease (CKD), or heart failure are often prescribed sodium–glucose cotransporter-2 inhibitors (SGLT2is) as a method of treatment. These drugs favorably affect glucose metabolism, as patients taking them have lower serum glucose levels. Another promising positive impact is protection against microvascular damage, cardiovascular disease, and chronic kidney disease. Nevertheless, fungal infections, urinary tract infections, and ketoacidosis are the adverse effects that might happen during the SGLT2i treatment. Fungal infections are more common among patients treated with these medications, including vulvovaginal Candidiasis in women and balanitis or balanoposthitis in men. Given the difficulty of treating fungal infections in patients with co-occurring diseases, we recommend that ongoing supervision of patients treated with SGLT2i include prevention and early detection of fungal infections.
