Circadian Clock Manipulation for Cancer Prevention and Control and the Relief of Cancer Symptoms

Life has evolved on this planet with regular daily spans of direct solar energy availability alternating with nocturnal spans of dark. Virtually every earth-borne life form has factored this circadian pattern into its biology to ensure the temporal coordination with its resonating environment, a task essential for its individual survival and that of its species. The first whole genome inspections of mutations in human colon and breast cancer have observed specific retained clock gene mutations. Single nucleotide polymorphisms within the genes of clock, clock-controlled, and melatonin pathways have been found to confer excess cancer risk or protection from cancer. Experimental studies have shown that specific core clock genes (Per2 and Per1) are tumor suppressors because their genetic absence doubles tumor numbers, and decreasing their expression in cancer cells doubles cancer growth rate, whereas their overexpression decreases cancer growth rate and diminishes tumor numbers. Experimental interference with circadian clock function increases cancer growth rate, and clinical circadian disruption is associated with higher cancer incidence, faster cancer progression, and shorter cancer patient survival. Patients with advanced lung cancer suffering greater circadian activity/sleep cycle disruption suffer greater interference with function, greater anxiety and depression, poorer nighttime sleep, greater daytime fatigue, and poorer quality of life than comparable patients who maintain good circadian integration. We must now determine whether strategies known to help synchronize the circadian clocks of normal individuals can do so in advanced cancer patients and whether doing so allows cancer patients to feel better and/or live longer. Several academic laboratories and at least 2 large pharmaceutical firms are screening for small molecules targeting the circadian clock to stabilize its phase and enhance its amplitude and thereby consolidate and coordinate circadian organization, which in turn is likely to help prevent and control human cancer. These drugs and strategies can, in turn, be used to make cancer patients with advanced disease feel and function more normally.

Cancer Complications

Cancer and its treatment can cause several complications, including:

  • Side effects of cancer treatment. Cancer treatments frequently cause side effects that can be temporary or that can last for months and years after treatment. Many side effects can be treated or managed. Ask your doctor what types of side effects you can expect from your cancer treatment. You may factor these side effects into your treatment decisions.
  • Unusual immune system reactions to cancer. In some cases your body’s immune system may react to the presence of cancer by attacking healthy cells. Called paraneoplastic syndromes, these unusual reactions can lead to a variety of signs and symptoms, such as fever, difficulty walking and seizures.
  • Cancer that spreads. As cancer advances it may spread (metastasize) to other parts of the body. Where cancer spreads depends on the type of cancer. In general, cancer that has spread may be managed, but can’t be cured.
  • Cancer that returns. Cancer survivors have a risk of cancer recurrence. Some cancers are more likely to recur than others. Ask your doctor about what you can do to reduce your risk of cancer recurrence. Your doctor may devise a follow-up care plan for you after treatment. This plan may include periodic scans and exams in the months and years after your treatment to look for cancer recurrence.

    Drawbacks and Gains of Dedicated Servers

    Majority of web hosting industries establish account on shared servers. Essentially, you are sharing the whole hard drive as well as bandwidth allocation with other individuals. This may appear to be an inferior option and can lead to a number of difficulties. With dedicated server, everything is totally yours and there are no other sites using the equal machine.

    The gains you will acquire with dedicated server are server security, storage space, data transfer, control panel, and software options. While the drawbacks will be the costs at the price is higher with shared server. Even though, you are assured that you will get the most out of the costs.

    A number of web hosting blog and web hosting reviews will explain more about dedicate servers.

    Circadian disruption has been linked with inflammation, an established cancer risk factor. Per3 clock gene polymorphisms have also been associated with circadian disruption and with increased cancer risk. Patients completed a questionnaire and provided a blood sample prior to undergoing a colonoscopy (n = 70).Adjusted mean serum cytokine concentrations (IL-6, TNF-alpha, gamma-INF, IL-1ra, IL-1-beta, VEGF) were compared among patients with high and low scores for fatigue (Multidimensional Fatigue Inventory), depressive symptoms (Beck Depression Inventory II), or sleep disruption (Pittsburg Sleep Quality Index), or among patients with different Per3 clock gene variants. Poor sleep was associated with elevated VEGF, and fatigue-related reduced activity was associated with elevated TNF-alpha concentrations. Participants with the 4/5 or 5/5 Per3 variable tandem repeat sequence had elevated IL-6 concentrations compared to those with the 4/4 genotype. Biological processes linking circadian disruption with cancer remain to be elucidated. Increased inflammatory cytokine secretion may play a role.
