Summary: The barrier-to-autointegration factor-like protein (BAF-L) plays an important role in spermiogenesis and spermatozoal function. Its genetic deletion in mice impairs spermiogenesis and male fertility, and reduced testicular expression of BAF-L is a risk factor for human male infertility.

Summary: Aging leads to age-associated diseases, particularly affecting the nervous system. Alzheimer's disease is a well-known example, characterized by the accumulation of neurofibrillary tangles and amyloid plaques. Therapeutic attempts targeting these aggregates have been unsuccessful, highlighting the need to understand the underlying mechanisms. Recent research has shown the importance of neuronal nucleus damage, specifically nuclear lamina damage, in the pathophysiology of the disease. This research perspective emphasizes the significance of targeting the neuronal nucleus for potential therapeutic interventions.

Summary: Mutations in LMNA and BANF1 genes can cause progeria, leading to accelerated aging. The proteins produced by these genes are involved in nuclear envelope rupture and repair processes. A-type lamins are recruited to the rupture sites in a BAF-dependent manner. Progeria-associated mutations inhibit the recruitment of A-type lamins to nuclear ruptures.

Summary: Heterochromatin is mainly localized at the nuclear periphery by interacting with the nuclear lamina and nuclear pore complexes. Recent studies have shown that these interactions play a crucial role in maintaining its peripheral localization, and there are differences in chromatin interactions with the nuclear envelope in cell populations and individual cells.

Summary: The study found that improper spermiogenesis leads to deregulation of ZP3R expression in globozoospermic spermatids, but even though the lack of GOPC causes failures in pre-acrosomal vesicle transport, the ZP3R protein still localizes in the acrosome and is only distributed through the cytoplasm during spermiogenesis.

Summary: Mutations in the LMNA gene cause laminopathies, a group of diverse diseases. LMNA-related cardiomyopathy is a common inherited heart disease with a poor prognosis. Research using mouse models, stem cells, and patient samples has characterized the phenotypic diversity caused by LMNA variants and contributed to understanding the molecular mechanisms underlying heart disease. This review focuses on the different cardiomyopathies caused by LMNA mutations, the role of LMNA in chromatin organization and gene regulation, and how these processes are disrupted in heart disease.

Summary: RepoMan, a regulatory subunit of protein phosphatase 1 (PP1), is transiently modified with SUMO-2 during late telophase, which enhances its binding affinity with lamin A and contributes to the recruitment and dephosphorylation of lamin A. Transient SUMOylation of RepoMan plays a crucial role in the spatiotemporal regulation of lamin A dephosphorylation and subsequent nuclear lamina formation at the end of mitosis.

Summary: The nuclear architecture of rod photoreceptor cells in nocturnal mammals differs from that of other animal cells, with euchromatin and heterochromatin occupying opposite positions. This unique structure is achieved through global relabeling of the rod cell epigenome, involving histone modifications such as H3K9 methylation. This study highlights the significance of epigenetic changes in shaping nuclear architecture in postmitotic cells.

Summary: The population in North Africa exhibits a high consanguinity rate and a potentially high proportion of founder mutations, which may contribute to the prevalence of recessive genetic disorders like Fanconi anemia. In this study, clinical, cytogenetic, and molecular characterization of FANCA in 29 North African FA patients was conducted, revealing high rates of spontaneous chromosome breakages and identifying several causal mutations. Furthermore, three founder mutations were identified in a majority of Tunisian patients, highlighting the importance of considering the mutational landscape in genetic counseling.

Summary: Bi-allelic mutations in the STIM1 gene result in CRAC channelopathy syndrome, characterized by symptoms such as muscle weakness and hyperlaxity. A novel homozygous frameshift mutation in STIM1, identified in this study, leads to complete loss of the STIM1 protein. The findings broaden the spectrum of phenotypes associated with STIM1 mutations.

Summary: Recent advances in sequencing technologies and the establishment of international standards for variant interpretation have led to a significant shift in diagnostic approaches in clinical genetics. However, the reclassification of variants that were originally considered pathogenic is still lacking in scientific literature and variant databases, hindering the interpretation of diagnostic sequencing results.

Summary: This study retrospectively collected clinical and neurophysiological data of CMT patients with MPZ mutations in French reference centers. The results showed heterogeneous manifestations of MPZ mutations causing axonal or demyelinating neuropathy and different age groups. Patients with early and adult onset CMT had higher disease severity, which progressed with age. To optimize patient selection for upcoming trials, inclusion criteria should consider disease pathophysiology and select patients with mild to moderate severity and onset between 18 and 50 years.

Summary: The secreted phospholipase A2 (PLA2G10) plays an important role in mouse fertilization by enhancing acrosome reaction and secretion, improving fertilization rate, and binding to PLA2R1 on gametes. It is shown that the catalytic activity and PLA2R1 binding of PLA2G10 both contribute to its profertility effect, and the study provides new insights into the complexity of PLA2G10's action in optimizing fertilization.

Summary: Liposarcomas are a heterogeneous group of sarcomas that require complete surgical resection and radiotherapy to prevent local recurrence. Understanding the genetic abnormalities that lead to liposarcoma initiation is crucial for the development of targeted therapies. Novel treatments targeting gene products of chromosome 12 are currently being considered in clinical trials to improve tumor control and survival rates.

Summary: This study revealed a significant lack of awareness among young adults in the UK regarding the potential impacts of gym lifestyles and supplementation on male infertility. Men were found to have a concerning lack of concern for their own fertility, with differences in awareness levels between men and women. It was also observed that men were more likely to consider making changes to their behavior if it had a long-term impact on their fertility compared to short-term effects.

Summary: Using a machine-learning model to determine the optimal trigger days can improve the outcomes of antagonist protocol cycles in freeze-all or fresh transfer cycles, for all age groups. Implementing these models can more accurately predict the number of retrieved oocytes, optimizing physicians' decisions, balancing workloads, and creating more standardized yet patient-specific protocols.

Summary: This study investigates the proteomic and phosphoproteomic differences in the endometrium of women with recurrent pregnancy loss (RPL) compared to healthy control women during different phases of the menstrual cycle. The results identify differentially expressed proteins and phosphorylated proteins, and highlight the insulin/cyclic nucleotide signalling pathway and AMPK/mTOR signalling pathway as major contributors to the abnormality of RPL endometrium. The findings provide insights into potential proteins associated with the pathogenesis of RPL and contribute to the identification of potential targets for RPL treatment.
