The active compound in marijuana, THC, can slow the growth of lung tumours and reduce the spread of the cancer in mice, a preliminary study reveals.
Human lung cancer tumours grew less than half as fast in mice that received moderate doses of the compound, the researchers reveal. They hope that drugs mimicking the apparent anti-cancer effects of tetrahydrocanabinol (THC) could one day help treat patients. The team strongly discourage people from self-medicating by smoking marijuana, noting that doing so could potentially encourage tumour growth.

Extracts from blueberries may reduce the size of tumours primarily found in infants and children, and improve survival, suggest new findings from a study with mice.
According to new results from the Ohio State University, mice fed the blueberry extract doubled their lifespan, and had tumours 60 per cent smaller that in control mice.

Our primary studies showed that berberine induced apoptosis in human tongue cancer SCC-4 cells in vitro. But there is no report to show berberine inhibited SCC-4 cancer cells in vivo on a murine xenograft animal model. SCC-4 tumor cells were implanted into mice and groups of mice were treated with vehicle, berberine (10mg/kg of body weight) and doxorubicin (4mg/kg of body weight). The tested agents were injected once per four days intraperitoneally (i.p.), with treatment starting 4 weeks prior to cells inoculation. Treatment with 4mg/kg of doxorubicin or with 10mg/kg of berberine resulted in a reduction in tumor incidence. Tumor size in xenograft mice treated with 10mg/kg berberine was significantly smaller than that in the control group. Our findings indicated that berbeirne inhibits tumor growth in a xenograft animal model. Therefore, berberine may represent a tongue cancer preventive agent and can be used in clinic.
MedWire News: Intralesional injection of interleukin (IL)-7 and IL-15 enhances the effects of radiofrequency thermal ablation (RFA) in inhibiting tumor development and metastases, animal study results show.
RFA, used for the treatment of solid tumors and known for its localized tumor effects, may activate immune responses and thereby reduce the risk for local tumor recurrence or distant metastases through T cell stimulation.
However, studies have suggested that additional adjuvant immunotherapy may improve the efficacy of RFA.
This preclinical study, reported in Breast Cancer Research and Treatment, was conducted to evaluate the effect of addition of the cytokines IL-7 and IL-15 to RFA in models of breast cancer.

ScienceDaily (June 11, 2009) - University of Florida researchers have come up with a new gene therapy method to disrupt cancer growth by using a synthetic protein to induce blood clotting that cuts off a tumor's blood and nutrient supply.
In mice implanted with human colorectal cancer cells, tumor volume decreased 53 percent and cancer cell growth slowed by 49 percent in those treated with a gene that encodes for the artificial protein, compared with those that were untreated.
Mice fed fish oil and curcumin showed a significantly reduced tumor volume, 25% (P < 0.04) and 43% (P < 0.005), respectively, and importantly, a combination of curcumin and fish oil diet showed > 72% (P < 0.0001) tumor volume reduction. Expression and activity of iNOS, COX-2, and 5-LOX are downregulated, and p21 is upregulated in tumor xenograft fed curcumin combined with fish oil diet when compared to individual diets. The preceding results evidence for the first time that curcumin combined with omega-3 fatty acids provide synergistic pancreatic tumor inhibitory properties.

DURHAM, N.C. -- Restricting carbohydrates, regardless of weight loss, appears to slow the growth of prostate tumors, according to an animal study being published this week by researchers in the Duke Prostate Center.
"Previous work here and elsewhere has shown that a diet light in carbohydrates could slow tumor growth, but the animals in those studies also lost weight, and because we know that weight loss can restrict the amount of energy feeding tumors, we weren't able to tell just how big an impact the pure carbohydrate restriction was having, until now," said Stephen Freedland, M.D., a urologist in the Duke Prostate Center and lead investigator on this study.
The researchers believe that insulin and insulin-like growth factor contribute to the growth and proliferation of prostate cancer, and that a diet devoid of carbohydrates lowers serum insulin levels in the bodies of the mice, thereby slowing tumor growth, Freedland said.
