Gender Gaps in the Measurement of Public Opinion About Homosexuality in Cross-national Surveys: A Question-Wording Experiment
Measures of attitudes towards homosexuality in cross-national studies have received criticism for not being ‘gender-sensitive’. The current study used a split-ballot design allowing for separate analyses of the attitudes towards ‘gay men and lesbian women’, ‘gay men’, and ‘lesbian women’ in a pooled sample of 3,381 participants from Great Britain, Hungary, and Portugal. Analyses controlling for sociodemographics showed that differences in attitudes towards male and female targets were generally small and did not interact with the gender of the rater. In addition, results showed that men’s attitudes towards homosexuality were more strongly related to their gender ideology than women’s attitudes. Implications of these findings for cross-national studies measuring attitudes towards homosexuality are discussed

Ormosianines A–P, Structurally Diverse Quinolizidine Alkaloids with AChE Inhibitory Effects from <i>Ormosia yunnanensis</i>
Sixteen new quinolizidine alkaloids (QAs), named ormosianines
A–P
(1–16), and 18 known congeners (17–34) were isolated from the stems and
leaves of Ormosia yunnanensis. The structures were
elucidated based on spectroscopic analyses and electron circular dichroism
(ECD) calculations. Structurally, ormosianines A (1)
and B (2) are the first examples of cytisine and Ormosia-type alkaloids with the cleavage of the piperidine
ring. Results of the acetylcholinesterase (AChE) inhibitory assay
revealed that the pentacycline Ormosia-type QAs,
including 1, 16, 24, and 27–29, are good AChE inhibitors. Ormosianine
A (1) exhibited more potent AChE inhibitory activity
with an IC50 value of 1.55 μM. Molecular docking
revealed that 1 might bind to the protein 1DX4, forming
two hydrogen bonds with residues SER-238 and HIS-480
Discovery of Novel and Potent Prolyl Hydroxylase Domain-Containing Protein (PHD) Inhibitors for The Treatment of Anemia
Stabilization
of hypoxia-inducible factor (HIF) by inhibiting prolyl hydroxylase
domain enzymes (PHDs) represents a breakthrough in treating anemia
associated with chronic kidney disease. Here, we identified a novel
scaffold for noncarboxylic PHD inhibitors by utilizing structure-based
drug design (SBDD) and generative models. Iterative optimization of
potency and solubility resulted in compound 15 which
potently inhibits PHD thus stabilizing HIF-α in vitro. X-ray cocrystal structure confirmed the binding model was distinct
from previously reported carboxylic acid PHD inhibitors by pushing
away the R383 and Y303 residues resulting in a larger inner subpocket.
Furthermore, compound 15 demonstrated a favorable in vitro/in vivo absorption, distribution,
metabolism, and excretion (ADME) profile, low drug–drug interaction
risk, and clean early safety profiling. Functionally, oral administration
of compound 15 at 10 mg/kg every day (QD) mitigated anemia
in a 5/6 nephrectomy rat disease model

Transcriptomic Characterization of Hepatocellular Carcinoma with <i>CTNNB1</i> Mutation
<div><p>Purpose</p><p>Hepatocellular carcinoma (HCC) is the sixth most common solid tumor worldwide and the third leading cause of cancer-related death. HCC is a particularly serious threat to the Chinese population. Although many molecular alterations are known to be involved in the tumorigenesis of hepatocytes, no systemic survey has examined the somatic mutations in HCC samples from Chinese patients. Our goal was to elucidate somatic mutations in Chinese HCC patients and investigate the possible molecular mechanisms involved in tumorigenesis.</p><p>Experimental Design</p><p>A total of 110 hepatitis B virus (HBV)-positive HCC samples and 46 HBV-negative HCC samples were genotyped for hot-spot mutations in the <i>CSF1R</i>, <i>CTNNB1</i>, <i>KRAS</i>, <i>BRAF</i>, <i>NRAS</i>, <i>ERBB2</i>, <i>MET</i>, <i>PIK3CA</i>, <i>JAK1</i>, and <i>SMO</i> genes. The transcriptomes of the <i><u>C</u>TNNB1</i> mutation-positive HCC samples from the H<u>B</u>V-positive patients (CB+ HCC) were compared to adjacent non-cancerous livers, and significantly altered genes were functionally validated <i>in vitro</i>.</p><p>Results</p><p><i>CTNNB1</i> mutations accounted for the majority of the mutations detected in our study. A slightly higher mutation rate was found in the HBV-positive patients than in their negative counterparts. A distinct pattern of <i>CTNNB1</i> mutation was detected in these two populations, and drastic changes at the transcriptomic level were detected in the CB+ tumors compared to adjacent non-cancerous livers. Potential tumor suppressors (FoxA3 and Onecut1) and oncogenes (MAFG and SSX1) were functionally validated.</p><p>Conclusions</p><p>Our work is the first systemic characterization of oncogenic mutations in HCC samples from Chinese patients. Targeting the Wnt-β-catenin pathway may represent a valid treatment option for Chinese HCC patients. Our work also suggests that targeting ONECUT1, FOXA3, SSX1, and MAFG may be a valid treatment option for CTNNB1 mutation positive HCC patients.</p></div
Statistical analysis of mutational information in the Chinese HCC patients.
<p>A: <i>CTNNB1</i> mutation is the predominant mutagenic event. Of the 156 samples assessed, 15 cases (9.6%) were found to have <i>CTNNB1</i> mutations. 14 cases (8.97%) had CTNNB1 mutation only, one case (0.64%) harbored CTNNB1 mutation and SMO (K575M) mutation, and one case (0.64%) had a KRAS (G12D) mutation. B: All of the mutations in CTNNB1 were clustered within the N-terminal region; five cases exhibited the T41A mutation, whereas three cases had the S37C mutation. The G34E and S45P mutations were found in two cases each, and the G34V, D32Y and D32G mutations were detected in only one case each in this study.</p
<i>CTNNB1</i> mutation-positive patients have a better prognosis.
<p>Statistical analysis of 110 HBV-positive patients and 46 HBV-negative HCC patients showed that the <i>CTNNB1</i> mutation-positive patients have a longer survival time; Difference was not significant.</p
