Glioblastoma, the most common primary malignant brain tumor in adults, carries a poor prognosis, with a median survival of just 15 months, significantly impacting patients’ quality of life. The aggressive growth of these highly vascularized tumors relies heavily on angiogenesis, driven primarily by vascular endothelial growth factor-A. Therefore, VEGF signaling pathway has become a prime therapeutic target in GBM treatment over the past decade. While anti-angiogenic treatment showed promise, agents like bevacizumab have ultimately failed to improve overall survival. This highlights the presence of compensatory angiogenic mechanisms that bypass VEGF inhibition, necessitating further investigation into resistance mechanisms and the development of more effective therapeutic strategies. This review examined the current landscape of anti-angiogenic agents for GBM, analyzed the mechanisms driving resistance to these therapies, and explored potential strategies for enhancing their effectiveness.

Curcumin, a polyphenol found in turmeric, demonstrates multifaceted anti-cancer activity against glioblastoma. Its therapeutic potential stems from its ability to modulate various molecular pathways implicated in glioblastoma development and progression, enhance the effectiveness of radiation therapy, and induce cancer cell death through diverse mechanisms, including apoptosis, autophagy, and cell cycle arrest. These combined actions make curcumin a promising candidate for glioblastoma treatment, warranting further investigation into its clinical application. In this review, we summarize the latest research on curcumin and its analogs’ potential in glioblastoma therapy.

A natural compound derived from the Pausinystalia yohimbe tree—yohimbine, has a rich history of use in traditional medicine and is currently being explored for its potential therapeutic applications. This indole alkaloid primarily acts as an antagonist of α2-adrenergic receptors. Initially recognized for its purported aphrodisiac properties, yohimbine has been investigated for a wide range of applications, including sports or the treatment of erectile dysfunction and metabolic disorders. However, toxicological concerns exist, particularly at higher doses. Ongoing researches help to fully assess yohimbine’s efficacy and safety profile and to explore strategies for enhancing its bioavailability and reducing toxicity. This review examines the multifaceted nature of yohimbine, delving into both its promising therapeutic potential and the associated risks.

Resveratrol, a naturally occurring polyphenolic compound found in various plants, has been extensively studied for its broad spectrum of beneficial biological effects. These encompass its potent antioxidant properties, anti-inflammatory activities, anti-aging capabilities, cardioprotective functions, and neuroprotective potential. The diverse biological actions of resveratrol extend beyond these well-established properties. It also exerts a significant impact on metabolic processes and bioavailability, and critically, it demonstrates the ability to effectively traverse the blood–brain barrier. This capacity to penetrate the central nervous system renders resveratrol a promising therapeutic agent for the management of central nervous system malignancies, as it has been shown to inhibit tumor cell proliferation, induce apoptosis, and modulate key signaling cascades, such as PI3K/Akt, JAK/STAT, and NF-kB. The multifaceted nature of resveratrol’s biological effects, including its influence on diverse physiological processes, underscores its potential as a valuable therapeutic option for the treatment of central nervous system tumors.

Melanoma is a type of skin cancer in which there is a strong correlation between its occurrence and exposure to ultraviolet radiation. Although it is not the most common skin cancer, it has the highest mortality rate of all skin cancers. The prognosis of patients is significantly worsened by melanoma metastasis to the brain, which often occurs in patients with advanced disease. The formation and development of melanoma metastases to the brain involve a very complex process, and their mechanisms are not fully understood. One of the ways for metastatic melanoma cells to survive and develop cancer in the brain environment is the presence of oncogenic BRAF mutation, which occurs in up to 50% of metastatic melanoma cases. Before discovering new methods of treating metastases, the overall survival of patients with this disease was 6 months. Currently, research is being conducted on new drugs using immunotherapy (immune checkpoint inhibitors: anti-PD-1, anti-CTLA-4) and targeted therapy (BRAF and MEK inhibitors) to improve the prognosis of patients. In this article, we summarize the current state of knowledge about the results of treating brain metastases with new systemic therapies.

Infrared and related light therapies are gaining increasing interest due to their potential therapeutic properties in treating various health conditions, particularly metabolic diseases such as insulin resistance and type 2 diabetes. These diseases often coexist with dyslipidemia, obesity, non-alcoholic fatty liver disease, and cardiovascular complications. This review paper analyzes the impact, primarily of far-infrared light therapy (FIR), on improving endothelial function, reducing oxidative stress, and modulating inflammatory responses—key factors in metabolic diseases. Preliminary studies suggest that FIR may improve blood circulation, increase the secretion of VEGF, and enhance insulin sensitivity by alleviating inflammatory states and oxidative damage commonly associated with these diseases. In addition, FIR has been associated with potential benefits in blood pressure regulation and lipid metabolism, which could contribute to reduced cardiovascular risk. However, it is important to acknowledge that most current evidence is derived from preclinical models and small-scale clinical trials, limiting direct applicability to broader patient populations. Moreover, significant variability exists in exposure parameters and treatment protocols across studies. While FIR therapy holds potential as a complementary approach to the conventional management of metabolic diseases, careful monitoring is essential to mitigate potential adverse effects. Further well-designed, large-scale clinical trials are necessary to validate the therapeutic efficacy, optimize treatment parameters, and comprehensively assess the safety profile of FIR interventions in metabolic health.
