Cyclic dinucleotides, which are a type of signaling substance for cancer treatment, are secondary messengers of intracellular events initiated by GPCR activation and act as a stimulator of interferon genes (STING), and thus can have a significant effect on tumor suppression. Meanwhile, when cancer occurs in a subject, angiogenesis and cell growth proceed at a very high rate in the body, and thus an oxygen-deficient environment is created due to incomplete angiogenesis in cancer tissues, which may be very suitable for the proliferation of anaerobic bacteria such as Salmonella sp. strains or E. coli. Therefore, the present invention relates to a DNA construct into which is introduced a gene for an enzyme that synthesizes a signaling substance for cancer treatment, e.g., a cyclic dinucleotide, or to a strain transformed with a vector comprising the DNA construct. The DNA construct or the strain transformed with a vector comprising the DNA construct, according to the present invention, targets cancer in a subject and then secretes C-di-AMP or C-di-GMP synthase in the surrounding environment of the cancer, and thus can very effectively prevent or treat cancer and, at the same time, can diagnose cancer in real time.

Cyclic dinucleotides (CDRs) are signaling molecules for cancer therapy, acting as second messengers for intracellular events initiated by GPCR activation and stimulating factors for the interferon gene (STING), thus significantly influencing tumor suppression. Simultaneously, when cancer occurs in a subject, angiogenesis and cell growth proceed at very high rates in vivo, creating a hypoxic environment due to incomplete angiogenesis in cancerous tissue. This environment can be highly conducive to the proliferation of anaerobic bacteria such as Salmonella strains or Escherichia coli. Therefore, this invention relates to a DNA construct incorporating a gene encoding an enzyme for synthesizing cancer therapeutic signaling molecules (e.g., CDRs), or to strains transformed with a vector containing the DNA construct. According to the invention, the DNA construct or strains transformed with a vector containing the DNA construct target cancer in a subject and then secrete C-di-AMP or C-di-GMP synthases in the surrounding environment of the cancer, thus enabling highly effective prevention or treatment of cancer while allowing for real-time cancer diagnosis.
