- The placenta produces a variety of steroid hormones through the catalytic activity of steroidogenic enzymes, including cytochrome P450 (CYP) hydroxylases and hydroxysteroid dehydrogenases (HSD). Large amounts of progesterone produced by the placenta are essential for the maintenance of pregnancy. Although androgens and estrogens are also elevated in maternal circulation during gestation, there are conflicting reports on whether de novo synthesis of these steroids occurs in the human placenta. To address this issue, we performed a comprehensive analysis of steroidogenic gene expression in early and term placenta. While none of the genes examined showed binary expression changes, 17β-HSDs, including HSD17B1 and AKR1C3, were markedly upregulated in the term placenta. CYP19A1 and HSD11B2 genes were also markedly upregulated. In contrast, CYP17A1, CYP21A2, CYP11B1, CYP11B2, and HSD17B3 were almost undetectable. Consistent with these findings, the plasma ratios of active to precursor sex steroids (estradiol/estrone and testosterone/androstenedione) were higher in pregnant than in non-pregnant women, although concentrations of all steroids increased. In contrast, plasma levels and profiles of 11-oxygenated androgens were unchanged. These results indicate that the human placenta does not significantly contribute to circulating levels of either classical or novel classes of androgens. Therefore, this study provides new insights into the tissue of origin and the physiological significance of sex steroids during gestation. - Source: PubMed

Yokohama YukoWatanabe YugoNakajima Ke-IchiUmezawa AkihiroTakahashi SatoruMori YasuhiroKato YasuhitoKawabe Jun-IchiYazawa Takashi - Breast cancer remains the most prevalent cancer among women, driving the continuous search for novel anticancer agents. In this study, a series of 10-alkoxy steroids containing a 1,4-dien-3-one moiety was synthesized via a one-step dearomatization of the A-ring of estradiol and an estrane derivative with a D-homo lactone moiety. All compounds exhibited favorable in silico ADMET properties, while five derivatives showed significant cytotoxic activity in vitro. The strongest effects against the estrogen-positive breast cancer cell line MCF-7 were observed for two 10β-methoxy, one 10β-butoxy, and two 10β-propargyloxy derivatives. The activity of the 10β-butoxy-17β-hydroxy and 10β-propargyloxy-17β-hydroxy steroids correlates with strong binding affinity toward estrogen receptor α and inhibition of AKR1C3 and AKR1C4 enzymatic activity. Additionally, the propargyloxy derivative showed substrate-like binding to human recombinant aromatase. Molecular docking results are in qualitative agreement with these findings, predicting binding modes similar to known ligands and possible hydrophobic interactions between the C-10 alkoxy groups and the active sites of target proteins, particularly the heme group of aromatase. These results highlight novel estrane derivatives as promising candidates for estrogen-positive breast cancer therapy through combined effects involving AKR1C3 inhibition and interaction with aromatase and estrogen receptor. - Source: PubMed

With lipidomics advances, AA metabolism's multifaceted roles in the tumor microenvironment (TME) have emerged, and it is recognized as a key driver and potential therapeutic axis in lung adenocarcinoma (LUAD). We utilized spatial transcriptomics sequencing (ST-seq) and LUAD-associated single-cell RNA sequencing (scRNA-seq) to explore crucial AA-related biomarkers in LUAD. - Source: PubMed

Sun ChongqiZhang YuchenPan YunXia GuixiYang GuangrongHuang ChunkaiLi JunMa Pei - Hepatocellular carcinoma (HCC) is one of the most prevalent malignant tumors globally, with liver cirrhosis (LC) recognized as a significant precursor. Xenobiotic metabolism plays a pivotal role in liver diseases, where the liver's primary function as a detoxifying organ directly influences health and tumor development. Therefore, exploring the function of genes associated with xenobiotic metabolism in patients with HCC and LC is crucial for advancing diagnosis and treatment strategies. - Source: PubMed

Xu HaoLi YanpengZhao RuiMa ShaoweiHu NingYu ShuoLv Xuefeng - Conventional allele specific PCR (AS-PCR) genotyping using gel electrophoresis and ethidium bromide (EtBr) is costly, particularly in developing countries. It also poses health risks to working personnel as it requires specialized equipment and toxic dyes like EtBr. Hence, the present study developed a simple and cost-effective colorimetric genotyping method using gold nanoparticles solution (AuNPs) and unmodified primers. Specifically, 15 μl of AuNPs solution was found sufficient for detecting an amplicon in 5 μl of PCR product. In this approach, the amplified PCR products appear red while the non-amplified PCR products appear blue with a PCR mastermix without a dye. Transmission Electron Microscopy (TEM) revealed the sequestration of AuNPs in amplified PCR products and the aggregation of AuNPs in non-amplified PCR products, resulting in red and blue colors, respectively. The method was tested on genotyping of six SNPs from six genes (Akr1c3, Plg, Myf5, Sec14l2, Tpm1, and Lama2) in buffaloes, and the results were perfectly matched with those obtained using agarose gel electrophoresis analysis. Therefore, the AS-PCR combined with AuNPs provides an easy visual detection method for the amplified and non-amplified PCR products of single-nucleotide polymorphisms (SNPs). In addition, the presented method has the potential to replace agarose gel electrophoresis, the use of EtBr, and UV-transilluminator. - Source: PubMed
