OBJECTIVES: We evaluated the potential effects of aspirin combined with vitamin D3 on cell proliferation and apoptosis in oral cancer cells. RESULTS: Compared to the untreated control or individual drug, the combinations of aspirin and vitamin D3 significantly decreased the rates of cell proliferation by CCK-8 assay, and caused higher rates of cell apoptosis in both CAL-27 and SCC-15 cells by Annexin V-FITC apoptosis assay and flow cytometry. Remarkably, the combined treatment with aspirin and vitamin D3 significantly suppressed the expression of Bcl-2 protein and p-Erk1/2 protein, examined by western blot analysis...

Living cells obtain energy either by oxidizing reduced compounds of organic or mineral origin or by absorbing light. Whichever energy source is used, some of the energy released is conserved by converting adenosine diphosphate (ADP) to adenosine triphosphate (ATP), which are analogous to the chemicals in a rechargeable battery. The energy released by the conversion of ATP back to ADP is used to drive most energy-requiring processes, including cell growth, cell division, communication and movement. It is clearly essential to life that the production and consumption of ATP are always maintained in balance, and the AMP-activated protein kinase (AMPK) is one of the key cellular regulatory systems that ensures this...

Studies have shown that aspirin and metformin play important roles in chemoprevention and repression of breast cancers, even though the exact mechanism remains unclear. Aspirin is capable of stimulating apoptosis through prostaglandin-dependent or prostaglandin-independent pathways. Metformin inhibits cell growth by enhancing the tumor suppressive function of transforming growth factor (TGF-β). In the present study, we report a new link between aspirin, metformin, TGF-β1 and murine breast cancer inhibition...

Omega-6 polyunsaturated fatty acid (n-6 PUFA) is the predominant polyunsaturated fatty acid (PUFA), especially in Western diet. A high omega-6/omega-3 ratio in Western diets is implicated in the development of cardiovascular diseases and inflammatory processes. Studies in animal models and in humans have demonstrated beneficial effects of omega-3 PUFA (n-3 PUFA) in a variety of diseases, including cardiac arrhythmias and inflammatory diseases, as well as breast and colon cancer. The molecular mechanisms underlying the effects of n-3 PUFA are still not well understood...

Early inhibition of inflammation suppresses the carcinogenic process. Aspirin is the most commonly used non-steroid anti-inflammatory drugs (NSAIDs), and it irreversibly inhibits cyclooxygenase-1 and -2 (COX1, COX2). Multiple randomized clinical trials have demonstrated that aspirin offers substantial protection from colon cancer mortality. The lower aspirin doses causing only minimal gastrointestinal disturbance, ideal for long-term use, can achieve only partial and transitory inhibition of COX2. Aspirin's principal metabolite, salicylic acid, is also found in fruits and vegetables that inhibit COX2...

BACKGROUND: Increasing data suggest that aspirin use may improve cancer survival; however, the evidence is sparse for ovarian cancer. METHODS: We examined the association between postdiagnosis use of low-dose aspirin and mortality in a nationwide cohort of women with epithelial ovarian cancer between 2000 and 2012. Information on filled prescriptions of low-dose aspirin, dates and causes of death, and potential confounding factors was obtained from nationwide Danish registries...

AIMS/HYPOTHESIS: Hyperglycaemia has been associated with the incidence of all and specific types of cancer, distinct from the risks related to diabetes. The relationships between blood glucose and mortality rates related to all and specific cancers were analysed in comparison with all-cause or non-cancer-related mortality rates in a large, general primary care population in France. METHODS: Between January 1991 and December 2008, 301,948 participants (193,221 men and 108,727 women), aged 16-95 years (mean ± SD 44...

Ovarian cancer is the leading cause of death of all gynaecological cancers. To date, there is no reliable, specific screening procedure for detecting ovarian cancer. The risk factors of ovarian cancer include modifiable and non-modifiable factors. The main goal of the ovarian cancer prevention program is to significantly reduce the risk of development of ovarian cancer and other cancers such as breast and/or peritoneal cancer. The application of non-surgical preventive approaches such as oral contraceptives, parity and breastfeeding has been shown to be highly protective against ovarian cancer development...

Blood platelets are crucial for maintaining hemostasis and several events in the wound-healing. However, platelet up-regulation leads to the development and the complications of several cardiovascular diseases. For the effective management of these complications, several synthetic drugs are in clinical practice such as aspirin and warfarin. since a long time. But some adverse reactions like aspirin resistance and bleed disorders cause patient in compliance and reduce their therapeutic potential. Thus, the search for potent and safer antiplatelet agents is of great interest...

In eukaryotic cells, autophagy is a process associated with programmed cell death. During this process, cytoplasmic proteins and organelles are engulfed by double-membrane autophagosomes, which then fuse with lysosomes to form autolysosomes. These autolysosomes then degrade their contents to recycle the cellular components. Autophagy has been implicated in a wide variety of physiological and pathological processes that are closely related to tumorigenesis. In recent years, an increasing number of studies have indicated that nonsteroidal anti-inflammatory drugs, such as celecoxib, meloxicam, sulindac, aspirin, sildenafil, rofecoxib, and sodium salicylate, have diverse effects in cancer that are mediated by the autophagy pathway...

BACKGROUND: Metabolic syndrome and obesity are linked with hyperuricemia, and it has also been proposed that oxidative stress associated with hyperuricemia may promote benign prostatic hyperplasia (BPH). However, it is currently unknown whether use of antihyperuricemic medication is associated with risk of developing BPH. We studied the association between BPH and use of antihyperuricemic allopurinol in a Finnish population-based cohort. METHODS: The study cohort consisted of 74,754 men originally identified for the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC)...

BACKGROUND: Several frequently used prescription drugs may affect bleeding risk. We investigated use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), selective serotonin reuptake inhibitors (SSRIs), and statins and risk of postoperative red blood cell transfusion in breast cancer patients. METHODS: Using Danish population-based registries, we identified a cohort of women who underwent surgery for primary breast cancer (n = 22,238) during 2005-2012 and ascertained their use of aspirin, NSAIDs, SSRIs, and statins...

Background: Colorectal cancer is the third most common cancer. Involvement of prostaglandin (PG) system in the pathogenesis of colorectal cancer has been suggested from clinical studies demonstrating therapeutic effect of NSAIDs including aspirin or selective COX-2 inhibitors. However, mechanisms on how PG regulates inflammatory responses leading to colorectal cancer development remain obscure. Further, careful attention is needed to use these drugs for a long time because of adverse effects due to non-specific inhibition of physiological PG production in addition to pathological one, making the development of alternatives to aspirin important...

BACKGROUND: Aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) may have a preventive effect against prostate cancer. However, evidence is limited and still controversial, especially considering non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs). METHODS: Swedish nationwide population-based cohort study including all long-term (≥180 days) adult male users of aspirin (n = 419,931) or NSAIDs (n = 223,437) followed from the first dispense date until the first cancer diagnosis, death or 31 December 2012, whichever occurred first...

PURPOSE: Aspirin could reduce the risk of cancer metastasis. Circulating tumor cells (CTCs) are a key factor of cancer metastasis, but no evidence has revealed how aspirin affects CTCs and its epithelial-mesenchymal transition (EMT). Here, we conducted a clinical trial to investigate how aspirin affects CTCs in metastatic colorectal cancer (MCC) and breast cancer patients (MBC). METHODS: The trial is retrospective registered at clinicaltrials.gov (NCT02602938). The eligible patients are given 100 mg aspirin q...
