Summary: We have created a database that integrates RNA-seq and ChIP-seq data to better understand the target genes of thyroid hormone receptors in different cell types. This database serves as a resource for studying the mode of action of thyroid hormone and provides a user-friendly tool to access specific gene information and extract gene lists of interest.

Summary: The storage of lipids as energy in adipose tissue is conserved, but there are substantial differences in the physiological activities of adipose tissues among species. This study characterized the transcriptional and lipidomic profiles of subcutaneous and visceral adipose tissues across 15 vertebrate species, spanning more than 300 million years of evolution. The data revealed greater variation in AT transcriptome and lipidome among species than within the same species, providing a resource for future studies on functional differences among adipose tissues in vertebrate species.

Summary: The study found that treatment with MET induces masculinization in Takifugu rubripes larvae, while T4 treatment does not feminize them. MET treatment suppresses the expression of foxl2 and cyp19a1a, and induces the expression of dmrt1. T4 treatment temporarily increases cyp19a1a expression in genetic XY gonads, but does not lead to feminization. Further investigation on the effects of higher concentrations of T4 or different concentrations of T3 on sex differentiation is needed.

Summary: This study investigated the causes of retained placenta (RP) in cattle using RNA-seq, hematologic and histologic experiments. The researchers identified differentially expressed genes (DEGs) related to immune system and lipid metabolism pathways in RP cows. They also found that estradiol-17 beta (E2) may be involved in RP development. In addition, histologic experiments showed structural differences in the placentome of RP cows. Complete blood cell (CBC) parameters were not significantly different between the RP and control groups.

Summary: This study aimed to identify potential lncRNA biomarkers for preeclampsia by analyzing the expression of lncRNAs in the placentas and plasma of patients. Six lncRNAs were validated and differentially expressed in preeclampsia placentas, two of which were also detected in maternal plasma, indicating their potential use as biomarkers for the disease.

Summary: This study profiles transcript expression profiles in human placental tissue samples and finds that early placental development is mainly regulated by differential transcript expression (DTE) rather than differential gene expression (DGE). Transcript usage is likely a regulatory mechanism in early placentation.

Summary: Impaired fetal growth is a major cause of prematurity, stillbirth, and infant mortality. This study investigated non-coding RNAs in the placentas of male and female fetuses with FGR. Dysregulation of lncRNAs was found to affect vasculature in female placentas, while immune processes were more affected in male placentas.

Summary: N-acyl amino acids (NAAs) are endogenous molecules that act as mitochondrial uncouplers in human adipocytes. While NAAs effectively induce uncoupled respiration, high concentrations of NAAs reduce adipocyte functionality and viability. Hence, the suitability of NAAs as anti-obesity agents without further chemical modifications is questionable.

Summary: This study found that cadmium exposure reduces placental angiogenesis in preeclampsia by decreasing the expression of PLGF and VEGF and increasing the expression of sFlt1. Cadmium exposure also decreases the expression of thyroid hormone receptor alpha and Dio2. These results suggest that cadmium exposure impairs placental angiogenesis in preeclampsia by disturbing thyroid hormone receptor signaling.

Summary: Salt stress is a major limiting factor for tomato growth and fruit quality. The study analyzed the relationship between hormones, transcription factors, and genes in tomatoes under salt stress, and constructed gene regulatory networks. The levels of ABA, SA, and JA increased significantly after salt treatment, while GA levels decreased. The study also identified hormone-related candidate genes associated with salt stress. This research provides valuable insights into the molecular mechanisms of salt tolerance in tomatoes.

Summary: Maternal obesity is associated with changes in infant fecal microbiome, short-chain fatty acids (SCFA), and human milk oligosaccharides (HMO). Offspring of women with obesity have lower abundance of SCFA-producing bacteria and lower levels of faecal butyric acid. Overall microbial richness may aid in prediction of elevated adiposity in later infancy.

Summary: Studies have shown that maternal chronic poor-quality diet, especially a high fat diet, is associated with reduced bone density and childhood fractures in offspring. The research findings indicate that maternal high fat diet changes histone methylation and acetylation epigenetic marks, which regulate the expression of genes controlling osteoblastogenesis.

Summary: The objective of this study was to characterize the changes in gut microbiota during pregnancy and to determine the effects of nutritional intervention on gut microbiota in women from sub-Saharan Africa, South Asia, and Central America. The results showed that the composition of gut microbial community changed significantly during pregnancy, with a decrease in alpha-diversity. Nutritional intervention did not have a significant impact on inflammatory biomarkers.

Summary: The gut microbiota plays a critical role in energy homeostasis and its dysbiosis is associated with obesity. Maternal high-fat diet and beta-adrenergic stimuli independently alter the gut microbiota, but their combined regulation is not clear. This study investigated the combined effect of these factors on offspring microbiota and found that maternal high-fat diet altered the offspring's response to beta-adrenergic stimuli, as well as microbial composition and function. Additionally, exposure to different temperatures also affected bacterial function.

Summary: Living donor liver transplantation (LDLT) is an effective solution for the organ shortage in the US, but there is limited understanding of the medical evaluation practices for living liver donors. A survey was conducted on all 53 active LDLT transplant programs in the US, revealing consensus on certain criteria such as minimum age and exclusion of obese donors, while variations existed in areas like acceptance of donors with diabetes mellitus. The findings highlight the need for data generation to develop evidence-based guidelines for the evaluation and risk assessment of living liver donors.

Summary: Biliary anastomotic stricture (BAS) is a common complication of liver transplantation with limited effective treatment options. In this case series, a novel percutaneous laser stricturotomy treatment was shown to be safe and effective in 5 post-transplant patients with refractory BAS. The laser excision and promotion of biliary re-epithelization yielded a 100% technical success rate and no recurrences at a mean follow-up time of 22 months.

However, further studies are needed for confirmation due to limited literature.

Summary: Perioperative dysfunction of the fibrinolytic system may contribute to adverse outcomes in liver transplant recipients. This study examined the association between fibrinolysis resistance (FR), measured by tissue plasminogen activator thrombelastography on postoperative day one, and early allograft dysfunction (EAD). The results showed that FR on POD-1 was significantly associated with increased risk of EAD and decreased graft survival time. This suggests that postoperative viscoelastic testing could be a useful tool in identifying liver transplant recipients at risk for EAD, particularly in those receiving donation after circulatory determination of death grafts.

Summary: This study challenges the current perception of the timing and benefits of DDLT in liver transplantation. The authors found that even at a low MELD-Na score of 12, DDLT provides a significant 1-year survival advantage compared to remaining on the waitlist, with a median estimated life years saved of over 9 years. Furthermore, as MELD-Na scores increase, the time-to-equal risk and time-to-equal survival decrease exponentially.
