Fertility and ovarian protection against chemotherapy-associated ovarian damage has formed a new field called oncofertility, which is driven by the pursuit of fertility protection as well as good life quality for numerous female cancer survivors. However, the choice of fertility and ovarian protection method is a difficult problem during chemotherapy and there is no uniform guideline at present. To alleviate ovarian toxicity caused by anticancer drugs, effective methods combined with an individualized treatment plan that integrates an optimal strategy for preserving and restoring reproductive function should be offered from well-established to experimental stages before, during, and after chemotherapy. Although embryo, oocyte, and ovarian tissue cryopreservation are the major methods that have been proven effective and feasible for fertility protection, they are also subject to many limitations. Therefore, this paper mainly discusses the future potential methods and corresponding mechanisms for fertility protection in chemotherapy-associated ovarian damage.

To characterize a novel gene, Homo sapiens LYR motif containing 1 (LYRM1), that is highly expressed in omental adipose tissue of obese subjects.

Methods and results

RT-PCR and western blot analysis confirmed that both mRNA and protein levels of LYRM1 were higher in omental adipose tissue of obese subjects than in normal weight subjects. RT-PCR analysis demonstrated that LYRM1 expression is widely distributed, with the highest levels of expression occurring in adipose tissue. A fusion protein of LYRM1 and green fluorescent protein as well as western blot analysis were used to identify the subcellular localization of LYRM1 in the nucleus. Based on Oil red O staining and the expression profile of specific differentiation markers, ectopic LYRM1 expression was not found to significantly affect adipogenesis. MTT assays and cell cycle analysis showed that LYRM1 promotes preadipocyte proliferation, and data from annexin V-FITC and caspase-3 activity assays further determined that LYRM1 can inhibit apoptosis of preadipocytes.


By increasing cell proliferation and lowering the rate of apoptosis, LYRM1 has the potential to modulate the size of the preadipocyte pool and influence adipose tissue homeostasis.
