Departments of Surgery, College of Medicine, Hanyang University222 Wangsimni-ro, Seongdong-gu, Seoul, 04763, South Korea.

Background: SSBP2, single-stranded DNA binding protein 2, is a subunit of the ssDNA-binding complex that is involved in the maintenance of genome stability. The majority of previous studies have suggested a tumor-suppressive role of SSBP2, which is silenced by promoter hypermethylation in several human malignancies, such as hematologic malignancies, prostate cancer, esophageal squamous cell carcinoma, ovarian cancer, and gallbladder cancer. However, an oncogenic role of SSBP2 has been suggested in glioblastoma patients. Read More

To evaluate the effect of ovarian biopsy and scratch on the resumption of ovarian function in women with premature ovarian insufficiency (POI), the follicle development and pregnancy outcome were retrospectively analyzed in women with POI after ovarian biopsy/scratch. Eighty patients with POI with secondary amenorrhea were accepted the laparoscopic surgery, and then hormone replacement treatment for 6 months was applied and in vitro fertilization and embryo transfer was suggested. No significant difference in clinical characteristics was observed before and after ovarian biopsy/scratch ( P > . Read More

Pregnancy and Ovarian Stimulation in the Patients with Breast Cancer.

Klin Onkol 2018 ;31(5):325-329

Background: Total 19% of patients diagnosed with breast cancer are younger than 50 years. Many of these patients will have postponed pregnancy into later life and many clinicians, who take care of these patients with mutations in tumor-suppressor genes, such as BRCA2, BRCA1, CHEK2, and others, recommend that it is better not to have a child than take the risk of developing a relapse. However, this recommendation can significantly reduce quality of life. Read More

Hepatocyte nuclear factor 1β (HNF1β) is mostly expressed in the liver, but is also expressed in other organs, like kidney, pancreas and genitourinary tract. In fact, HNF1β, a member of the superfamily of homeodomain-containing transcription factors, has been described as a hallmark in clear cell carcinomas. However, its role as an oncogene or as tumor suppressor gene remains controversial. Read More
