The role of oestrogen and oestrogencalcium axis in endometrial carcinoma

Unopposed oestrogen is recognised as an inducer of endometrial cancer.Over the past 50 years,the effects of oestrogen on the endometrium and endometrial cancer have been a hot topic in the field of gynaecological oncology.In recent years,a series of studies by our team revealed that the non-genomic transcriptional effects of oestrogen can influence the progression of endometrial carcinoma by regulating calcium ions,suggesting that inhibiting calcium ion channelproteins could serve as an adjuvant therapy for endometrial cancer.In this review,we retrospectively summarise the sources of oestrogen in vivo,the effects of oestrogens on the uterus and endometrium,oestrogen signalling and the clinical application of oestrogen-related compounds,emphasising the significant role of oestrogen-calcium axis inhibition in adjuvant therapy for endometrial cancer.

m6A甲基化修饰在精子发生中的研究进展

N6-甲基腺嘌呤(N6-methyladenosine,m6A)甲基化作为真核生物中最常见的RNA修饰,通过甲基化转移酶、去甲基化酶、甲基化识别蛋白三种调控因子参与多种细胞进程和疾病进展。近年来的研究表明m6A甲基化修饰参与了精子发生的整个过程,其失调造成的生精障碍可能导致男性不育。本文就m6A调控因子在睾丸中的时空表达、m6A甲基化在精子发生中的作用机制以及m6A甲基化调控异常与男性不育等方面的研究进展作一综述,旨在为男性不育的基础研究和临床治疗提供参考。
