Dietary acrylamide intake and the risk of lymphatic malignancies: the Netherlands Cohort Study on diet and cancer.

BackgroundAcrylamide, a probable human carcinogen, is present in many everyday foods. Since the finding of its presence in foods in 2002, epidemiological studies have found some suggestive associations between dietary acrylamide exposure and the risk of various cancers. The aim of this prospective study is to investigate for the first time the association between dietary acrylamide intake and the risk of several histological subtypes of lymphatic malignancies.MethodsThe Netherlands Cohort Study on diet and cancer includes 120,852 men and women followed-up since September 1986. The number of pe

Hypothesis: are neoplastic macrophages/microglia present in glioblastoma multiforme?

Most malignant brain tumours contain various numbers of cells with characteristics of activated or dysmorphic macrophages/microglia. These cells are generally considered part of the tumour stroma and are often described as TAM (tumour-associated macrophages). These types of cells are thought to either enhance or inhibit brain tumour progression. Recent evidence indicates that neoplastic cells with macrophage characteristics are found in numerous metastatic cancers of non-CNS (central nervous system) origin. Evidence is presented here suggesting that subpopulations of cells within human gliomas

The nutrigenomic-epigenetic axis in cancer: from dietary bioactives to precision oncology.

Cancer development and progression are increasingly understood to arise from dynamic interactions between genetic alterations and environmentally driven epigenetic regulation, with dietary exposures representing one of the most biologically influential and modifiable factors. Given the expanding evidence linking nutrition to epigenomic remodeling, a comprehensive synthesis of how specific dietary components influence cancer-relevant epigenetic mechanisms is needed to clarify their preventive and therapeutic relevance. This review brings together mechanistic, epidemiologic, and translational fi

Роль антиоксидантов в множестве миеломы: диагностика, прогнозирование и терапевтическое применение: обзор сюжета.

Множественная миэлома (ММ) — злокачественная клетка B-клеток с моноклональными плазменными клетками, производящими нефункциональные иммуноглобулины. Она по-прежнему неизлечима из-за de novo или приобретенного сопротивления злокачественных клеток стандартным химиотерапиям. Таким образом, понимание механизма терапевтического сопротивления имеет важнейшее значение для разработки более эффективных мер вмешательства и определения новых целей лечения. MM - это разнородная болезнь, характеризующаяся сложными генетическими изменениями, которые имеют решающее значение для прогнозирования стратификации.

The Impact of Iron on Cancer-Related Immune Functions in Oncology: Molecular Mechanisms and Clinical Evidence.

Iron metabolism plays a dual role in cancer, serving as an essential nutrient for cellular functions and a potential catalyst for tumor growth and immune evasion. Here, we cover the complex interplay between iron levels within the serum or in the microenvironment and cancer therapy, focusing on how iron deficiency and overload can impact immune function, tumor progression, and treatment efficacy. On the one hand, we highlight iron deficiency as a factor of primary immune responses and its adverse effects on anti-cancer immunotherapy efficacy. On the other hand, we also stress the impact of iro

A review of feline infectious peritonitis virus infection.

Feline infectious peritonitis (FIP) is an infectious disease characterized by non-specific laboratory changes and clinical signs. Clinical symptoms include anorexia, jaundice, fever, and weight loss. Moreover, some lesions are found in the digestive and respiratory systems. FIP, whose virulence varies, cannot be distinguished using several diagnostic methods. Moreover, feline coronaviruses (FCoVs) can be classified into two serotypes based on differences in their amino acid sequences, spike (S) protein sequences, and antibody (Ab) neutralization. There are two pathotypes, namely those caused b

Prevention of Anthracycline-Induced Cardiotoxicity: The Good and Bad of Current and Alternative Therapies.

Doxorubicin (Dox)-induced cardiotoxicity (DIC) remains a serious health burden, especially in developing countries. Unfortunately, the high cost of current preventative strategies has marginalized numerous cancer patients because of socio-economic factors. In addition, the efficacy of these strategies, without reducing the chemotherapeutic properties of Dox, is frequently questioned. These limitations have widened the gap and necessity for alternative medicines, like flavonoids, to be investigated. However, new therapeutics may also present their own shortcomings, ruling out the idea of "natur

Ferroptosis and its emerging role in esophageal cancer.

The occurrence and development of tumors involve a series of life activities of cells, among which cell death has always been a crucial part in the research of tumor mechanisms and treatment methods. Ferroptosis is a non-apoptotic form of cell death, which is characterized by lipid peroxidation accumulation and further cell membrane rupture caused by excessive production of intracellular oxygen free radicals dependent on iron ions. Esophageal cancer is one of the common digestive tract tumors. Patients in the early stage are mainly treated with surgery, and the curative effect is awe-inspiring

Rational drug repositioning for coronavirus-associated diseases using directional mapping and side-effect inference.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen of coronavirus disease 2019 (COVID-19), has infected hundreds of millions of people and caused millions of deaths. Looking for valid druggable targets with minimal side effects for the treatment of COVID-19 remains critical. After discovering host genes from multiscale omics data, we developed an end-to-end network method to investigate drug-host gene(s)-coronavirus (CoV) paths and the mechanism of action between the drug and the host factor in a directional network. We also inspected the potential side effect of the ca

Alkylating anticancer agents and their relations to microRNAs.

Alkylating agents represent an important class of anticancer drugs. The occurrence and emergence of tumor resistance to the treatment with alkylating agents denotes a severe problem in the clinics. A detailed understanding of the mechanisms of activity of alkylating drugs is essential in order to overcome drug resistance. In particular, the role of non-coding microRNAs concerning alkylating drug activity and resistance in various cancers is highlighted in this review. Both synthetic and natural alkylating agents, which are approved for cancer therapy, are discussed concerning their interplay w

Trial watch: Immunostimulatory cytokines in cancer therapy.

Tumor-targeting immune responses provide a significant contribution to (when they do not entirely account for) the clinical activity of diverse antineoplastic regimens, encompassing not only a large panel of immunotherapeutic strategies but also conventional cytotoxic molecules, targeted anticancer agents and irradiation. In line with this notion, several approaches have been devised to elicit novel or boost existing anticancer immune responses, including the administration of immunomodulatory cytokines. Such a relatively unspecific intervention suffices to mediate clinical effects in (at leas

Targeting DNA Damage Response and Repair to Enhance Therapeutic Index in Cisplatin-Based Cancer Treatment.

Platinum-based chemotherapies, such as cisplatin, play a large role in cancer treatment. The development of resistance and treatment toxicity creates substantial barriers to disease control, yet. To enhance the therapeutic index of cisplatin-based chemotherapy, it is imperative to circumvent resistance and toxicity while optimizing tumor sensitization. One of the primary mechanisms by which cancer cells develop resistance to cisplatin is through upregulation of DNA repair pathways. In this review, we discuss the DNA damage response in the context of cisplatin-induced DNA damage. We describe th
