Is there an optimal timing interval between hCG trigger and oocyte vitrification?

Taiwanese Journal of Obstetrics & Gynecology, 2022
Objective: Oocyte vitrification has been developed as a promising alternative to slow freezing; however, the clinical outcome is highly operator dependent.

Sperm-oocyte interplay: an overview of spermatozoon’s role in oocyte activation and current perspectives in diagnosis and fertility treatment

Cell & Bioscience, 2021
The fertilizing spermatozoon is a highly specialized cell that selects from millions along the female tract until the oocyte. The paternal components influence the oocyte activation during fertilization and are fundamental for normal embryo development ...

Endoplasmic Reticulum (ER) Stress and Unfolded Protein Response (UPR) in Mammalian Oocyte Maturation and Preimplantation Embryo Development

International Journal of Molecular Sciences, 2019
Mammalian oocytes and early embryos derived from in vitro production are highly susceptible to a variety of cellular stresses. During oocyte maturation and preimplantation embryo development, functional proteins must be folded properly in the endoplasmic

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

Molecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

Oocyte specific lncRNA variant Rose influences oocyte and embryo development

Non-coding RNA Research, 2021
Fully grown mammalian oocytes store a large amount of RNA synthesized during the transcriptionally active growth stage. A large part of the stored RNA belongs to the long non-coding class which contain either transcriptional noise or important ...

Multi‐omic characterization of consensus molecular subtype 1 (CMS1) colorectal cancer with dampened immune response improves precision medicine

Molecular Oncology, EarlyView.
This study highlights the importance of multi‐omic analyses in characterizing colorectal cancers. Indeed, our analysis revealed a rare CMS1 exhibiting dampened immune activation, including reduced PD‐1 expression, moderate CD8+ T‐cell infiltration, and suppressed JAK/STAT pathway.

Oocyte In Vitro Maturation with Crude Sperm Extract Protein of Bull's Spermatozoa

Journal of Experimental Life Science, 2016
Oocyte In vitro maturation (IVM) is one of the important parts for in vitro fertilization (IVF). The success of oocyte maturation is influenced by the composit ion and the quality of IVM medium.

Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible
