Retama monosperma n-hexane extract induces cell cycle arrest and extrinsic pathway-dependent apoptosis in Jurkat cells.

BACKGROUND: Retama monosperma L. (Boiss.) or Genista monosperma L. (Lam.), locally named as "R'tam", is an annual and spontaneous plant belonging to the Fabaceae family. In Morocco, Retama genus is located in desert regions and across the Middle Atlas and it has been widely used in traditional medicine in many countries. In this study, we show that Retama monosperma hexane extract presents significant anti-leukemic effects against human Jurkat cells. METHODS: Human Jurkat cells, together with other cell lines were screened with different concentrations of Retama monosperma hexane extract at d

Leptin reverts pro-apoptotic and antiproliferative effects of α-linolenic acids in BCR-ABL positive leukemic cells: involvement of PI3K pathway.

It is suspected that bone marrow (BM) microenvironmental factors may influence the evolution of chronic myeloid leukaemia (CML). In this study, we postulated that adipocytes and lipids could be involved in the progression of CML. To test this hypothesis, adipocytes were co-cultured with two BCR-ABL positive cell lines (PCMDS and K562). T cell (Jurkat) and stroma cell (HS-5) lines were used as controls. In the second set of experiments, leukemic cell lines were treated with stearic, oleic, linoleic or α-linolenic acids in presence or absence of leptin. Survival, proliferation, leptin production

Synergistic effect of conjugated linolenic acid isomers against induced oxidative stress, inflammation and erythrocyte membrane disintegrity in rat model.

BACKGROUND: α-Eleostearic acid and punicic acid, two typical conjugated linolenic acid (CLnA) isomers present in bitter gourd and snake gourd oil respectively, exhibit contrasting cis-trans configuration which made them biologically important. METHODS: Rats were divided into six groups. Group 1 was control and group 2 was treated control. Rats in the groups 3 and 4 were treated with mixture of α-eleostearic acid and punicic acid (1:1) (0.5% and 1.0% respectively) while rats in the groups 5 and 6 were treated with 0.5% of α-eleostearic acid and 0.5% of punicic acid respectively along with sodi

Hepatic farnesyl diphosphate synthase expression is suppressed by polyunsaturated fatty acids.

Dietary vegetable oils and fish oils rich in PUFA (polyunsaturated fatty acids) exert hypocholesterolaemic and hypotriglyceridaemic effects in rodents. The plasma cholesterol-lowering properties of PUFA are due partly to a diminution of cholesterol synthesis and of the activity of the rate-limiting enzyme HMG-CoA reductase (3-hydroxy-3-methylglutaryl-CoA reductase). To better understand the mechanisms involved, we examined how tuna fish oil and individual n-3 and n-6 PUFA affect the expression of hepatic FPP synthase (farnesyl diphosphate synthase), a SREBP (sterol regulatory element-binding p

Significance of long chain polyunsaturated fatty acids in human health.

In the last decades, the development of new technologies applied to lipidomics has revitalized the analysis of lipid profile alterations and the understanding of the underlying molecular mechanisms of lipid metabolism, together with their involvement in the occurrence of human disease. Of particular interest is the study of omega-3 and omega-6 long chain polyunsaturated fatty acids (LC-PUFAs), notably EPA (eicosapentaenoic acid, 20:5n-3), DHA (docosahexaenoic acid, 22:6n-3), and ARA (arachidonic acid, 20:4n-6), and their transformation into bioactive lipid mediators.

Полиненасыщенные жирные добавки к кислоте в системе управления множественным склерозом: обзор анализа.

Полиинунасыщенные жирные кислоты (PUFA) уже давно исследованы в качестве потенциальной адъюнктурной терапии множественных склерозов из-за их иммуномодулятивных, антивоспалительных и нейрозащитных свойств. Вместе с тем имеющиеся данные по-прежнему являются разнородными и не были полностью картированы. Цель этого аналитического обзора заключалась в том, чтобы охарактеризовать данные о дополнении ПУФП, выявить тенденции в области исследований и пробелы в знаниях, а также придать контекстуальный характер результатам первичных исследований наряду с систематическими обзорами.

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

МЕТОДЫ: Это тематическое исследование включало 34 больные с недавно диагностированными гематологическими заболеваниями12 лимфо

Effects of the polyunsaturated fatty acids, EPA and DHA, on hematological malignancies: a systematic review.

Omega-3 polyunsaturated fatty acids (PUFAs) have well established anti-cancer properties. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are among this biologically active family of macromolecules for which various anti-cancer effects have been explained. These PUFAs have a high safety profile and can induce apoptosis and inhibit growth of cancer cells both in vitro and in vivo, following a partially selective manner. They also increase the efficacy of chemotherapeutic agents by increasing the sensitivity of different cell lines to specific anti-neoplastic drugs. Various mechanisms

Может ли дополнение антиоксидантами улучшить когнитивные функции у пациентов с множественным склерозом? Обзор литературы.

Множественный склероз (MS) — хроническое нервно-воспалительное и нейродегенеративное заболевание центральной нервной системы (CNS), имеющее сложную и многофакторную патофизиологию. Хотя эти механизмы еще не полностью прояснились, установлено, что окислительный стресс (ОС) играет ключевую роль в вождении нейродегенерации в MS. Эти патологические механизмы способствуют возникновению широкого круга симптомов, включая моторные и сенсорные расстройства, а также когнитивное расстройство. Дефекты когнитивных функций могут создавать для этих пациентов тяжелое бремя и существенно влиять на качество их

Methyl jasmonate: putative mechanisms of action on cancer cells cycle, metabolism, and apoptosis.

Methyl jasmonate (MJ), an oxylipid that induces defense-related mechanisms in plants, has been shown to be active against cancer cells both in vitro and in vivo, without affecting normal cells. Here we review most of the described MJ activities in an attempt to get an integrated view and better understanding of its multifaceted modes of action. MJ (1) arrests cell cycle, inhibiting cell growth and proliferation, (2) causes cell death through the intrinsic/extrinsic proapoptotic, p53-independent apoptotic, and nonapoptotic (necrosis) pathways, (3) detaches hexokinase from the voltage-dependent

Screening the Active Phytochemicals From Eclipta prostrata and Unraveling Their Molecular Insight Into Human Malignancies.

Current drugs against multiple human malignancies are limited, and developing new treatment strategies is improbable within a short time. So, considering the current situation, phytochemicals could be a viable option for developing chemotherapeutic agents for managing numerous types of malignancies. Therefore, we aimed to locate all phytochemicals of Eclipta prostrata and unravel their chemotherapeutic mechanisms and strategies individually. We defined 25 active compounds based on their anticancer activities after filtering through IMPPAT and literature search, and these compounds have chemoth

Protective Effects of Omega-3 Fatty Acids in Cancer-Related Complications.

Omega-3 polyunsaturated fatty acids (PUFAs) are considered immunonutrients and are commonly used in the nutritional therapy of cancer patients due to their ample biological effects. Omega-3 PUFAs play essential roles in cell signaling and in the cell structure and fluidity of membranes. They participate in the resolution of inflammation and have anti-inflammatory and antinociceptive effects. Additionally, they can act as agonists of G protein-coupled receptors, namely, GPR40/FFA1 and GPR120/FFA4. Cancer patients undergo complications, such as anorexia-cachexia syndrome, pain, depression, and p
