The Bacterial Protein promoting Cancer

Viral Oncology :  The Bacterial Protein promoting Cancer DNA K, a protein of the bacterium mycoplasma, interferes with the mycoplasma-infected cell's ability to respond to and repair DNA damage, a known origin of cancer.  Little or no mycoplasma DnaK DNA sequences were found associated with the tumor, which was fully developed, suggesting a hit-and-run or hide mechanism of transformation, indicating that the damage is done early, but the protein may not be needed once the cancer cells are formed.                   Mycoplasmas are a family of bacteria that are associated with cancers, especially in people with HIV. Researchers utilized immune-compromised mice as a model for analyzing the effect of mycoplasma infection on the development of lymphoma. They compared how quickly non-infected immune-compromised mice developed lymphoma compared to mycoplasma-infected immune-compromised mice. The mice were infected with a strai...

Novel Nano vaccine to treat skin cancer/melanoma

Vaccines & Vaccinology : Novel Nano vaccine for Melanoma Researchers have developed a novel Nano-vaccine for melanoma, the most aggressive type of skin cancer that begins in melanocytes. Their experiments have proven effective in preventing the development of melanoma and in treating primary tumours and metastases that result from melanoma. The focus of the research was on a nanoparticle that serves as the basis for the new vaccine. Melanoma develops in the skin cells, which is called the melanocytes, produce melanin or skin pigment. The fight against skin cancer/melanoma is becoming advanced over the years through a variety of treatment modalities & experiments, such as immunotherapy, radiation therapy & chemotherapy , but the vaccine approach, which has a great effect against various viral diseases, has not materialized yet against cancer. Scientists have shown that it is possible to produce an effective Nano-vaccine against melanoma/skin cancer and to sensitize...
