Abstract: The invention provides novel methods of determining or comparing potency of a test interferon relative to rSIFN-co (an interferon having therapeutic effects on solid tumors); methods of establishing substantial equivalence between a test interferon and rSIFN-co; as well as methods for determining potency of a test interferon, kits for determination of such methods, and an interferon or an interferon substitute having said activities.

Abstract: The invention provides novel methods of determining or comparing potency of a test interferon relative to rSIFN-co (an interferon having therapeutic effects on solid tumors); methods of establishing substantial equivalence between a test interferon and rSIFN-co; methods for down-regulation of expression of Wnt-related receptors or co-receptors, such as LRP6/FZD6; down-regulation of expression of Wnt-related target genes, such as, Axin2, CD24, Survivin and/or ID2; inhibition of beta-catenin/TCF transcriptional activities; suppression of expression of beta-catenin; up-regulation of tumor suppressor genes, such as DKK-3, BATF2 and/or KLF4; inhibition of tumor cell viability in vitro; inhibition of tumor growth and metastases in vivo; inhibition of tumor cell migration, pseudopod formation, and colony formation in vitro; as well as methods for determining potency of a test interferon, kits for determination of such methods, and an interferon or an interferon substitute having said activities.

Abstract: This invention provides a method for treating tumors in a subject, comprising administering to the subject an effective amount of a recombinant interferon, wherein the interferon has the amino acid sequence of SEQ ID NO:2 and is encoded by the nucleotide sequence SEQ ID NO:1, wherein the tumors are selected from the group consisting of skin cancer, basal cell carcinoma, liver cancer, thyroid cancer, rhinopharyngeal cancer, solid carcinoma, prostate cancer, esophageal cancer, pancreatic cancer, superficial bladder cancer, hemangioma, epidermoid carcinoma, cervical cancer, glioma, leucocythemia, acute leucocythemia, chronic leucocythemia, lymphadenoma, and polycythemia vera.

Abstract: This invention provides crystalline recombinant interferon (rSIFN-co (SEQ ID NO: 1)) having (i) the same amino acid sequence as that of human consensus interferon, and (ii) altered three-dimensional structure as compared to IFN-?2b. The interferon of the present invention exhibits enhanced biological activities. The present invention also provides a structural model of said interferon useful for drug screening and/or drug design, and mimetics of said interferon.

Abstract: This invention provides a method for inducing cell senescence by recombinant interferon with altered spatial configuration, wherein the interferon is encoded by a nucleotide sequence having the sequence of SEQ ID NO.2.

Abstract: This invention provides a recombinant interferon (rSIFN-co) and its equivalent with changed spatial configuration, high efficacy and low side effects. Therefore, high dose of rSIFN-co may be used. The cytotoxic effect of rSIFN-co is only one-eighth (?) of currently clinically available interferons but its anti-viral effect is approximately five to twenty (5-20) times higher, and when used in vivo it has a broader spectrum of clinical applications and longer biofeedback response. This invention further provides methods of using the recombinant interferon to treat proliferative disorders such as cancer or viral diseases.

Abstract: This invention provides a recombinant super-compound interferon or an equivalent thereof with changed spatial configuration. The super-compound interferon possesses anti-viral or anti-tumor activity and, therefore, is useful in preventing and treating viral diseases and cancers. This invention also provides an artificial gene which codes for the super-compound interferon or its equivalent. Finally, this invention provides methods for producing recombinant super-compound interferon or its equivalent and various uses of said interferon.
