A correlation between anorexia and brain levels of serotonin and tryptophan (TRP) has been reported in tumor-bearing animals. In the present investigation 45 patients with various types of cancer and 13 control subjects were studied. Prior to the study the patients had received no antineoplastic

Highlights at the gate of tryptophan catabolism: a review on the mechanisms of activation and regulation of indoleamine 2,3-dioxygenase (IDO), a novel target in cancer disease.

Indoleamine 2,3-dioxygenase (IDO) catalyzes the first and rate-limiting step of Kynurenine pathway along the major route of Tryptophan catabolism. The scientific interest in the enzyme has been growing since the observations of the involvement of IDO in the mechanisms of immune tolerance and in the

Tumor growth is accompanied by an anorexia mediated by humoral factors that appear to influence appetitive mechanisms in the brain. Because tumor resection is followed by resumption of normal food intake, the circulating anorexigenic substance(s) are produced either by the neoplastic tissue or by

Diminished quality of life in patients with cancer correlates with tryptophan degradation.

OBJECTIVE Quality of life (QoL) is frequently impaired in patients suffering from malignant disease. Disturbed metabolism of neurotransmitter serotonin might be crucially involved, and serotonin-precursor tryptophan is degraded during pro-inflammatory immune response. In this study, we compared QoL

Fatigue in patients with lung cancer is related with accelerated tryptophan breakdown.

BACKGROUND Patients with cancer often suffer from fatigue and decreased quality of life which might be related to the breakdown of essential amino acid tryptophan. METHODS In 50 patients with lung cancer we examined fatigue and the deterioration of quality of life in patients using the Functional

Tryptophan is an amino acid required by all life forms for protein synthesis and other important metabolic functions. It is metabolized in the body using the kynurenine pathway which involves the enzyme indoleamine 2,3 dioxygenase (IDO) and its transport is regulated through the L-type amino acid

Combination of long-acting microcapsules of the D-tryptophan-6 analog of luteinizing hormone-releasing hormone with chemotherapy: investigation in the rat prostate cancer model.

The effect of combining hormonal treatment consisting of long-acting microcapsules of the agonist [D-Trp6]LH-RH (the D-tryptophan-6 analog of luteinizing hormone-releasing hormone) with the chemotherapeutic agent cyclophosphamide was investigated in the Dunning R-3327H rat prostate cancer model.

Celastrol is well known for its anti-cancer effects, yet its specific mechanisms against colon cancer are still not fully elucidated. In this study, cytotoxic effect of celastrol against HCT116 colon cancer cells was investigated based on cell viability assay and flow cytometry assay, and the

Effect of the association of 1-methyl-DL-tryptophan with paclitaxel on the expression of indoleamine 2,3-dioxygenase in cultured cancer cells from patients with breast cancer.

Breast cancer is the most common type of cancer among women and the survival of patients affected by it is increasing, mainly due to several new approaches in early diagnosis and more effective treatments. The enzyme indoleamine 2,3-dioxygenase (IDO) is expressed in many cells, including tumor

Development of screen-printed tryptophan-kynurenine immunosensor for in vitro assay of kynurenine-mediated immunosuppression effect of cancer cells on activated T-cells.

The development of analytical methods that respond to the emerging need to perform rapid 'in situ' analyses of human metabolic pathways (HMPs) demonstrates disposable screen-printed electrodes (SPEs) as an alternative to the traditional tools. In the kynurenine pathway, one of the important HMPs,

The indoleamine-2,3-dioxygenase (IDO) inhibitor 1-methyl-D-tryptophan upregulates IDO1 in human cancer cells.

1-methyl-D-tryptophan (1-D-MT) is currently being used in clinical trials in patients with relapsed or refractory solid tumors with the aim of inhibiting indoleamine-2,3-dioxygenase (IDO)-mediated tumor immune escape. IDO is expressed in tumors and tumor-draining lymph nodes and degrades tryptophan

Plasma levels of total tryptophan were significantly lower in 51 patients with breast cancer than in 14 women with benign breast cancer following surgery and after 12 weeks. The urinary excretion of xanthurenic and 5-hydroxyindoleacetic acids were similar in patients with cancer and benign disease

Although cognitive dysfunction is a prevalent and disruptive problem for many breast cancer survivors (BCSs), little research has examined its etiology. One potential mechanism that remains to be explored is serotonin. Serotonin has been implicated in normal and dysfunctional cognitive processes,
