Biochemical and Clinical Impact of Organic Uremic Retention Solutes: A Comprehensive Update.

In this narrative review, the biological/biochemical impact (toxicity) of a large array of known individual uremic retention solutes and groups of solutes is summarized. We classified these compounds along their physico-chemical characteristics as small water-soluble compounds or groups, protein bound compounds and middle molecules. All but one solute (glomerulopressin) affected at least one mechanism with the potential to contribute to the uremic syndrome. In general, several mechanisms were influenced for each individual solute or group of solutes, with some impacting up to 7 different biolo

Deregulation of the EGFR/PI3K/PTEN/Akt/mTORC1 pathway in breast cancer: possibilities for therapeutic intervention.

The EGFR/PI3K/PTEN/Akt/mTORC1/GSK-3 pathway plays prominent roles in malignant transformation, prevention of apoptosis, drug resistance and metastasis. The expression of this pathway is frequently altered in breast cancer due to mutations at or aberrant expression of: HER2, ERalpha, BRCA1, BRCA2, EGFR1, PIK3CA, PTEN, TP53, RB as well as other oncogenes and tumor suppressor genes. In some breast cancer cases, mutations at certain components of this pathway (e.g., PIK3CA) are associated with a better prognosis than breast cancers lacking these mutations. The expression of this pathway and upstre

Cancer stem cells: advances in knowledge and implications for cancer therapy.

Cancer stem cells (CSCs), a small subset of cells in tumors that are characterized by self-renewal and continuous proliferation, lead to tumorigenesis, metastasis, and maintain tumor heterogeneity. Cancer continues to be a significant global disease burden. In the past, surgery, radiotherapy, and chemotherapy were the main cancer treatments. The technology of cancer treatments continues to develop and advance, and the emergence of targeted therapy, and immunotherapy provides more options for patients to a certain extent. However, the limitations of efficacy and treatment resistance are still i

Comprehensive review of targeted therapy for colorectal cancer.

Colorectal cancer (CRC) is among the most lethal and prevalent malignancies in the world and was responsible for nearly 881,000 cancer-related deaths in 2018. Surgery and chemotherapy have long been the first choices for cancer patients. However, the prognosis of CRC has never been satisfying, especially for patients with metastatic lesions. Targeted therapy is a new optional approach that has successfully prolonged overall survival for CRC patients. Following successes with the anti-EGFR (epidermal growth factor receptor) agent cetuximab and the anti-angiogenesis agent bevacizumab, new agents

The effects of twenty-four nutrients and phytonutrients on immune system function and inflammation: A narrative review.

BACKGROUND AND AIM: Recently, optimal immune function has become a primary focus of worldwide attention not only in the prevention of chronic disease but also as one strategy to reduce the severity of acute illness. Inflammation, a process largely controlled by the immune system, has long been studied and recognized for its role in chronic disease. Optimizing immune function or managing inflammation using individual nutrients and phytonutrients is not well understood by the average person. Thus, this narrative literature review summarizes many of the more recent findings about how certain nutr

Recent advances and challenges of cellular immunotherapies in lung cancer treatment.

Lung cancer is a major malignant tumor with high morbidity and fatality rates. For many years, traditional treatments for lung cancer have struggled to achieve a favorable outlook and prognosis. It is crucial to identify and innovate novel clinical therapeutic strategies and techniques to prevent tumor progression and prolong the survival time of patients with lung cancer. Cellular immunotherapies have revolutionized the treatment of malignant tumors and have been gradually applied in clinical practice. CAR-T therapy is the best-known cellular therapy and has achieved remarkable clinical outco

Lymph node metastasis in cancer progression: molecular mechanisms, clinical significance and therapeutic interventions.

Lymph nodes (LNs) are important hubs for metastatic cell arrest and growth, immune modulation, and secondary dissemination to distant sites through a series of mechanisms, and it has been proved that lymph node metastasis (LNM) is an essential prognostic indicator in many different types of cancer. Therefore, it is important for oncologists to understand the mechanisms of tumor cells to metastasize to LNs, as well as how LNM affects the prognosis and therapy of patients with cancer in order to provide patients with accurate disease assessment and effective treatment strategies. In recent years

Bispecific antibodies: unleashing a new era in oncology treatment.

Advancements in diagnostic and therapeutic standards have substantially enhanced the survival of patients with malignant tumors. Nevertheless, the quest for effective strategies to address resistant or recurrent advanced tumors remains a critical and unwavering objective. Bispecific antibodies (BsAbs) unleashed a new era of anti-tumor treatment by simultaneously binding to two distinct targets, thereby enhancing specificity, minimizing off-target toxicities, and synergistically modulating anti-tumor immunity and the tumor microenvironment. Compared with the combination of two monoclonal antibo

Революция онкологии: роль искусственного интеллекта (AI) в качестве антителного дизайна и средств оптимизации.

Антитела играют решающую роль в защите человеческого тела от болезней, включая такие опасные для жизни заболевания, как рак. Они оказывают посреднические услуги в связи с иммунной реакцией на иностранные антигены и, в некоторых случаях, на самоантигены. С течением времени антителные технологии эволюционировали от моноклонных антител (mAbs) до химерика антигенных рецепторов Т (клеток CAR-T), оказывая значительное влияние на биотехнологию, диагностику и лечение. Хотя эти достижения способствовали активизации терапевтического вмешательства, интеграция искусственного интеллекта (АИ) революционизир

Metabolic reprogramming and therapeutic resistance in primary and metastatic breast cancer.

Metabolic alterations, a hallmark of cancer, enable tumor cells to adapt to their environment by modulating glucose, lipid, and amino acid metabolism, which fuels rapid growth and contributes to treatment resistance. In primary breast cancer, metabolic shifts such as the Warburg effect and enhanced lipid synthesis are closely linked to chemotherapy failure. Similarly, metastatic lesions often display distinct metabolic profiles that not only sustain tumor growth but also confer resistance to targeted therapies and immunotherapies. The review emphasizes two major aspects: the mechanisms driving

Endoplasmic reticulum stress in disease pathogenesis: its implications for therapy.

Endoplasmic reticulum (ER) stress is a key cellular mechanism that is important in the development of many diseases, including cancer. Since the discovery of the unfolded protein response (UPR), research has greatly improved our understanding of how ER stress affects cellular functions, especially protein folding and adaptation to stress. The UPR consists of three main branches: IRE1, ATF6, and PERK, each of which is crucial for regulating stress responses, protein homeostasis, and apoptosis. These pathways normally help cells handle stress effectively; however, excessive or prolonged activati

Advances in Diet and Physical Activity in Breast Cancer Prevention and Treatment.

There is currently a growing interest in diets and physical activity patterns that may be beneficial in preventing and treating breast cancer (BC). Mounting evidence indicates that indeed, the so-called Mediterranean diet (MedDiet) and regular physical activity likely both help reduce the risk of developing BC. For those who have already received a BC diagnosis, these interventions may decrease the risk of tumor recurrence after treatment and improve quality of life. Studies also show the potential of other dietary interventions, including fasting or modified fasting, calorie restriction, keto
