Patent number: 8524228Abstract: Methods and compositions for male or female contraception are provided. The compositions include an effective amount of netrin-1 to reduce or inhibit sperm concentration in semen of males or to inhibit or reduce fusion of male gametes with female gametes in a female subject Still another embodiment provides a method for diagnosing male infertility by determining the amount of netrin-1 in a sample of epididymal fluid or semen from a male subject, comparing the amount of netting-1 in the sample to levels of netrin-1 in samples of epididymal fluid or semen from fertile males, wherein levels of netrin-1 in the sample from the male subject that are higher or lower than levels of netrin-1 in samples from fertile males are indicative of male infertility in the male subject.Type: GrantFiled: November 3, 2008Date of Patent: September 3, 2013Assignee: Medical College of Georgia Research Institute, Inc.Inventors: Wen-Cheng Xiong, Jae-Ho Lee, Lin Mei

Patent number: 8461114Abstract: Modulating the interaction between ErbB2 and Erbin is an effective method for treating one or more symptoms of ErbB2-mediated disorders. It has been discovered that Erbin stabilizes ErbB2 in vivo and inhibiting the formation of heterodimers between Erbin and ErbB2 reduces or inhibits the biological activity of ErbB2 relative to control levels. Reducing the biological activity of ErbB2 is useful in the treatment of conditions characterized by the overexpression or misregulation of ErbB2. These conditions include, but are not limited to breast cancer and prostate cancer. Alternatively, agonist of Erbin that promote or enhance the interaction of Erbin with ErbB2 can be useful in the treatment of certain neurological disorders. It has also been discovered that Erbin plays a role in the myelination of neurons of the peripheral nervous system.Type: GrantFiled: May 14, 2010Date of Patent: June 11, 2013Assignee: Medical College of Georgia Research Institute, Inc.Inventors: Lin Mei, Yanmei Tao, Wen-Chen Xiong
