Background: Argininosuccinate synthase (ASS1) is a pivotal enzyme involved in the urea cycle, playing a crucial role in aspartate catabolism, arginine and nitric oxide biosynthesis. These biological processes are crucial for the growth and development of mammals. However, the functions of urea cycle-related genes in mouse embryonic stem cells (mESCs) remain largely unclear.

As an interspecies hybrid inheriting genetic material from horse and donkey lineages, mules provide a unique model for studying allele-specific regulatory dynamics. Here, we isolated adult fibroblasts (AFs) and placental fibroblasts (PFs) from mule tissues and reprogrammed them into induced pluripotent stem cells (iPSCs). Intriguingly, placental fibroblast-derived iPSCs (mpiPSCs) exhibited reduced reprogramming efficiency compared to adult fibroblast-derived iPSCs (maiPSCs).

Cognitive Frailty (CF) is a clinical syndrome characterized by the co-occurrence of physical frailty and cognitive impairment in the absence of dementia. This geriatric condition has emerged as a significant contributor to compromised health status and diminished quality of life among aging populations, yet its underlying pathological mechanisms remain incompletely elucidated. Chronic low-grade inflammation, recognized as a hallmark of biological aging, has been implicated in the pathogenesis of multiple age-related diseases, including hypertension, diabetes, panvascular diseases, and cerebrovascular disorders.

The sika deer (Cervus nippon) is a large ruminant species of significant commercial value, with antlers used in traditional medicine and meat prized for its nutritional and culinary qualities. In this study, we cultured fibroblasts from sika deer fetal fibroblasts (SDFs) and then reprogrammed them into sika deer induced pluripotent stem cells (SD-iPSCs) using nine exogenous factors (OCT4, SOX2, C-MYC, KLF4, NANOG, LIN28, RARG, LRH1 and LARGE T). The resulting SD-iPSCs exhibited to expressed key pluripotent genes, maintained genomic stability, and differentiated into the three germ layers in teratoma assays.

The medaka spermatogonial stem cell line (SG3) is a well-established cell line that can be induced to differentiate into sperm in vitro. Ranavirus, a genus of viruses widely distributed among fish, amphibians, and reptiles, poses a significant threat to these organisms. This study aimed to investigate the morphological changes and transcriptomic responses in SG3 following infection with three ranavirus strains: Andrias davidianus ranavirus (ADRV), Rana grylio virus (RGV), and Siniperca chuatsi ranavirus (SCRaV).

NOD-like receptor (NLR) family proteins are implicated in various cardiovascular diseases. However, the precise role of NLRC5, the largest member of this family, in myocardial infarction (MI) remains poorly understood. This study reveals that NLRC5 is upregulated in the hearts of both patients with MI and MI mice.

Myocardial infarction (MI) often results in significant loss of cardiomyocytes (CMs), contributing to adverse ventricular remodelling and heart failure. Therefore, promoting CM survival during the acute stage of MI is crucial. This study aimed to investigate the potential role of GPX3 in cardiac repair following MI.

Article Synopsis
  • Restoring the expression of factors that aid neonatal heart regeneration in adults can enhance heart repair, emphasizing the need for research in this area.
  • The study identified a protein called Ankrd1, which regulates heart cell proliferation and is crucial for heart regeneration and repair, especially after damage.
  • Findings showed that increasing Ankrd1 levels can improve cardiac function and recovery following a heart attack, positioning Ankrd1 as a promising target for future heart disease treatments.

Article Synopsis
  • The study investigates the effects of rhCHK1, a recombinant protein, on improving heart cell survival and growth after ischemia/reperfusion injury in pigs, with findings suggesting enhanced cardiac repair and function.
  • Researchers found that injecting rhCHK1 not only stimulated heart cell division and reduced inflammation within days but also improved overall heart function and minimized damage over a month post-injury.
  • The mechanism behind these effects involves CHK1 binding to and activating specific sites on the PKM2 protein, leading to changes in metabolism that support heart cell renewal and repair processes.

Background: Numerous studies have investigated the association between CDH1 polymorphisms and gastric cancer (GC) risk. However, the results have been inconsistent and controversial. To further determine whether CDH1 polymorphisms increase the risk of GC, we conducted a meta-analysis by pooling the data.

Programmed death-1 and its ligand-1 (PD-1/PD-L1), immune checkpoints proteins, play a crucial role in anti-tumor responses. A large number of studies have evaluated the relationships of PD-1/PD-L1 polymorphisms with risk of cancer, but evidence for the associations remains inconsistent. Therefore, we performed a meta-analysis to examine the associations between PD-1/PD-L1 single nucleotide polymorphisms (SNPs) and cancer predisposition.

Sesamin, a special compound present in sesame and sesame oil, has been reported a role in regulating lipid metabolism, while the underlying mechanisms remain unclear. Autophagy has been reported associated with lipid metabolism and regarded as a key modulator in liver steatosis. The present work aimed to investigate whether sesamin could exert its protective effects against lipid accumulation via modulating autophagy in HepG2 cells stimulated with oleic acid (OA).

Article Synopsis
  • The adult mammalian heart has limited regenerative ability, while the neonatal heart can regenerate, making it a focus for treating heart diseases like myocardial infarction and heart failure.
  • The study investigates the role of cellular nucleic acid binding protein (CNBP) in cardiac regeneration, finding that high CNBP levels promote cardiomyocyte (CM) growth and survival while low levels hinder it.
  • CNBP enhances DNA replication and cell cycle progression by increasing β-catenin and its targets, suggesting it's a promising therapeutic target for repairing heart damage.

Although a virus can regulate many cellular responses to facilitate its replication by interacting with host proteins, the host can also restrict virus infection through these interactions. In the present study, we showed that the host eukaryotic translation elongation factor 1 alpha (eEF1A), an essential protein in the translation machinery, interacted with two proteins of a fish rhabdovirus, rhabdovirus (SCRV), and inhibited virus infection via two different mechanisms: (i) inhibiting the formation of crucial viral protein complexes required for virus transcription and replication and (ii) promoting the ubiquitin-proteasome degradation of viral protein. We also revealed the functional regions of eEF1A that are involved in the two processes.

Article Synopsis
  • CHK1-targeted cancer therapies can increase the risk of heart problems, especially when combined with gemcitabine, but the exact reasons for this are not well understood.
  • The study used human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) and mouse models to investigate the cardiotoxic effects caused by these treatments, finding that they led to mitochondrial damage and heart dysfunction.
  • The research highlighted the importance of mitochondrial CHK1, which helps maintain mitochondrial function, and suggested that boosting levels of SIRT3 could be a promising strategy to protect against heart damage related to these cancer therapies.

Infection by severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) has posed a severe threat to global public health. The current study revealed that several inhibitors of protein kinases C (PKCs) possess protective activity against SARS-CoV-2 infection. Four pan-PKC inhibitors, Go 6983, bisindolylmaleimide I, enzastaurin, and sotrastaurin, reduced the replication of a SARS-CoV-2 replicon in both BHK-21 and Huh7 cells.
