Increased systemic free fatty acids (FFA) impair insulin sensitivity. In obese and diabetic subjects, production of tumor necrosis factor-alpha (TNF-alpha), a proinflammatory cytokine, is elevated. TNF-alpha has a variety of effects by inducing inflammation, decreasing glucose utilization, and

Tumor necrosis factor (TNF) activates both p42 and p44 mitogen-activated protein kinases (MAPK) in human FS-4 fibroblasts, cells for which TNF is mitogenic. We now show that TNF activates p42 MAPK in two cell lines whose growth is inhibited by TNF. A mutant TNF that binds only to the p55 TNF

There is evidence that aspirin and other non-steroidal anti-inflammatory drugs may be protective agents against cancer in the gastrointestinal tract. These effects are particularly well documented for the colon and rectum. Some epidemiological and experimental studies have suggested that aspirin

Induction of stromelysin gene expression by tumor necrosis factor alpha is inhibited by dexamethasone, salicylate, and N-acetylcysteine in synovial fibroblasts.

Proinflammatory cytokines, altered connective tissue metabolism, and overexpression of matrix metalloproteinases (MMPs) such as stromelysin compared to tissue inhibitors of metalloproteinases (TIMPs) result in synovial inflammation and erosion of arthritic cartilage. Tumor necrosis factor alpha

Etoposide (VP-16) uptake by tumour spheroids and activity in the presence of Brij 30, formulation additives and sodium salicylate.

A number of additives typically used in the formulation of poorly soluble drugs can be shown to influence drug transport across various physiological barriers. Multicellular spheroids from a human neuroblastoma cell line (NB1-G) were used to investigate the effect of etoposide in solution, as its

Activation of p38 mitogen-activated protein kinase by sodium salicylate leads to inhibition of tumor necrosis factor-induced IkappaB alpha phosphorylation and degradation.

Many actions of the proinflammatory cytokines tumor necrosis factor (TNF) and interleukin-1 (IL-1) on gene expression are mediated by the transcription factor NF-kappaB. Activation of NF-kappaB by TNF and IL-1 is initiated by the phosphorylation of the inhibitory subunit, IkappaB, which targets

The aspirin metabolite salicylate inhibits breast cancer cells growth and their synthesis of the osteolytic cytokines interleukins-6 and -11.

Some epidemiological studies have suggested that aspirin could be a chemopreventive agent against breast cancer. We tested the effects of the aspirin metabolite salicylate (SA) on four (Hs578T, MCF-7, MDA-MB-231, and T-47D) breast cancer cell (BCC) lines in vitro. Two features were studied: the

Might salicylate exert benefits against childhood cancer?

Childhood cancers are a broad range of diseases. Research on the chemopreventive potential of non-steroidal anti-inflammatory drugs, such as aspirin (acetylsalicylate) has yet to be fully directed towards childhood cancers. A prima facie hypothesis on salicylate and childhood cancer would therefore

Acetylsalicylic acid and sodium salicylate inhibit LPS-induced NF-kappa B/c-Rel nuclear translocation, and synthesis of tissue factor (TF) and tumor necrosis factor alfa (TNF-alpha) in human monocytes.

We have investigated the effects of acetylsalicylic acid and sodium salicylate on the LPS-induced synthesis of the pro-coagulant protein tissue factor (TF) and the pro-inflammatory protein tumor necrosis factor-alpha (TNF-alpha), as well as the prostaglandin PGE2 in human monocytes. Both drugs

Preadministration of high-dose salicylates, suppressors of NF-kappaB activation, may increase the chemosensitivity of many cancers: an example of proapoptotic signal modulation therapy.

NF-kappaB activity is elevated in a high proportion of cancers, particularly advanced cancers that have been treated previously. Cytotoxic treatment selects for such up-regulation inasmuch as NF-kappaB promotes transcription of a large number of proteins that inhibit both the intrinsic and extrinsic

The mutations most common in pancreatic cancer decrease the ability to control G1 to S cell cycle progression and cellular proliferation. In colorectal cancer cells, nonsteroidal anti-inflammatory drugs inhibit proliferation and induce cell cycle arrest. We examined whether sodium salicylate, an

5,6,7-Trimethoxy flavonoid salicylate derivatives were designed by the joining of three important pharmacophores (TMP, flavonoid, and SA) according to the combination principle. A series of novel trimethoxy flavonoid salicylate derivatives were synthesized and their in vitro anti-tumor activities

OBJECTIVE Tumor metastasis is the major cause of colorectal cancer (CRC) mortality. Nonsteroidal antiinflammatory drugs (NSAIDs) such as aspirin have been shown to have an antineoplastic effect in CRC cell lines. Different patients, however, exhibit different chemosensitivity. In this study, we

Despite advances in breast cancer treatment, mortality from breast cancer is still high. Undoubtedly, novel treatment strategies are needed for chemoprevention of high-risk women and for the treatment of receptor-negative breast cancer. An appealing strategy would be the combination of breast
