N4‐acetylcytidine in LncRNA Gm26917 Promotes Translation in Female Germline Stem Cells by Recruiting Ribosomal Protein mRNA via EEF1A1

Advanced Science, EarlyView.
This work establishes that ac4C modification on lncRNA Gm26917 governs its spatial interactions with Rpl10 mRNA, and RBP EEF1A1 mediates the interaction between Gm26917 and Rpl10. It elucidates a novel ac4C‐Gm26917‐EEF1A1‐Rpl10 axis in FGSC maintenance both in vitro and in vivo, and provides a potential molecular target for modulating germ cell ...

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

Advanced Science, EarlyView.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

The Effects of Unemployment on Fertility:Evidence from England [PDF]

, 2016
This paper reinvestigates the causal effects of local unemployment on fertility. It argues that contradicting results in the existing empirical research may have arisen due to a neglect of sub-demographic differences and failure to recognize endogeneity.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

Advanced Science, EarlyView.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, EarlyView.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

TFR for males in Denmark: Calculation and tempo-correction

Demographic Research, 2015
Background: Studies of trends and tempo corrections of fertility have focused on female rather than male fertility; one reason being that the necessary detailed data are more widely available for mothers than for fathers.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

Advanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

From stress signals to fertility challenges: the role of damage-associated molecular patterns in male reproduction

Frontiers in Immunology
Male infertility is influenced by genetic abnormalities, hormonal imbalances, lifestyle factors, and environmental exposures. Recently, Damage-Associated Molecular Patterns (DAMPs) have emerged as key players in male reproductive health, particularly in ...

Sertoli Cell‐Derived Extracellular Vesicles Orchestrate Cadmium‐Induced Testicular Inflammation and Fibrosis

Advanced Science, EarlyView.
Environmental cadmium exposure disrupts testicular homeostasis through a novel intercellular communication axis. Stressed Sertoli cells release extracellular vesicles carrying damage‐associated molecular patterns and mitochondrial fragments, which activate macrophages via TLR4/NF‐κB signaling.

DNAJB7 is dispensable for male fertility in mice

Reproductive Biology and Endocrinology, 2023
Background DNAJBs are highly conserved proteins that are involved in various biological processes. Although several DNAJBs are highly expressed in the testis, the function of DNAJB7 in spermatogenesis and male fertility remains unclear.
