Agricultural mulch is beneficial to agricultural production, but it will cause serious environmental pollution. Poly(butylene adipate-co-terephthalate) (PBAT) mulch has the potential to replace PE mulch to reduce the microplastic pollution in farmland soil. To clarify the effects of the aging behavior of PBAT mulch on soil microbial community composition.

Tumor-specific antigens (TSAs) are crucial for tumor-specific immune response that reduces tumor burden and thus serve as important targets for immunotherapy. Identification of novel TSAs can provide new strategies for immunotherapies. In this study, we demonstrated that the upstream open reading frame (uORF) of encodes an antigenic peptide (RNF10 uPeptide), capable of eliciting a T cell-mediated anti-tumor immune response.

Background: Pancreatic ductal adenocarcinoma (PDAC) is characterised by limited responses to chemoimmunotherapy attributed to highly desmoplastic tumor microenvironment. Disrupting the tumor-stromal cell crosstalk is considered as an improved PDAC treatment strategy, whereas little progress has been made due to poor understanding of its underlying mechanism. Here, we examined the cellular role of melanoma associated antigen A isoforms (MAGEA) in regulating tumor-stromal crosstalk mediated chemoresistance.

Research Question: To determine whether blastocyst quality affects the sex ratio at birth through a single blastocyst frozen - thawed embryo transfer (SBFET) cycle.

Design: In this retrospective analysis, we examined 3,041 singleton infants born following SBFET between 2017 and 2020 at a single institution. We compared the sex ratios of these infants with respect to the blastocyst quality, embryo growth rate, and morphology.

Study Question: Do inactivated coronavirus disease-2019 (COVID-19) vaccines affect IVF outcomes among the vaccine recipients?

Summary Answer: The receipt of inactivated COVID-19 vaccines before ovarian stimulation has little effect on the outcomes of IVF, including ovarian stimulation outcomes, embryo development and pregnancy rates.

What Is Known Already: Limited studies have reported that COVID-19 vaccines do not affect ovarian function, embryo development or pregnancy outcomes.

Study Design, Size, Duration: This was a retrospective cohort study performed at the Third Affiliated Hospital of Guangzhou Medical University on 240 women vaccinated with either CoronaVac or Sinopharm COVID-19 before ovarian stimulation in the exposed group and 1343 unvaccinated women before ovarian stimulation in the unexposed group.

Unlabelled: Despite substantial advances in the treatment of solid cancers, resistance to therapy remains a major obstacle to prolonged progression-free survival. Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive cancers, with a high level of liver metastasis. Primary PDAC is highly hypoxic, and metastases are resistant to first-line treatment, including gemcitabine.

Defective pericyte-endothelial cell interaction in tumors leads to a chaotic, poorly organized and dysfunctional vasculature. However, the underlying mechanism behind this is poorly studied. Herein, we develop a method that combines magnetic beads and flow cytometry cell sorting to isolate pericytes from tumors and normal adjacent tissues from patients with non-small cell lung cancer (NSCLC) and hepatocellular carcinoma (HCC).

Article Synopsis
  • Sphingolipid metabolism is significantly dysregulated in non-small cell lung carcinoma (NSCLC), with B3GNT5 and GAL3ST1 showing strong correlations to patient prognosis.
  • A detailed analysis involving sphingolipidomics of sera and genetically modified NSCLC cell lines revealed specific metabolites that may serve as better biomarkers than standard clinical ones for patient staging.
  • The study indicates that B3GNT5 and GAL3ST1 play crucial but opposite roles in regulating sphingolipid metabolism, impacting cancer growth and progression in lung cancer.

Aberrant glycosylation in pancreatic cancer has been linked to cancer development, progression and chemoresistance. However, the role of glycogene, such as galactosyltransferase, in pancreatic cancer remains unknown. Herein, we establish beta-1.

Enhanced blood vessel (BV) formation is thought to drive tumor growth through elevated nutrient delivery. However, this observation has overlooked potential roles for mural cells in directly affecting tumor growth independent of BV function. Here we provide clinical data correlating high percentages of mural-β3-integrin-negative tumor BVs with increased tumor sizes but no effect on BV numbers.

Background: Accumulating studies suggest that targeting epigenetic modifications could improve the efficacy of tumor immunotherapy; however, the mechanisms underlying this phenomenon remain largely unknown. Here, we investigated the ability of the epigenetic modifier, enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2), to regulate the expression of immune checkpoint inhibitor, programmed death-1 ligand 1 (PD-L1) in hepatocellular carcinoma (HCC).

Methods: Immunohistochemistry and multiplex immunofluorescence staining were performed to analyze the expression and correlation of EZH2 and PD-L1 in HCC tissues.

We recently identified CXCR4 as a novel vascular marker for vessel sprouting in hepatocellular carcinoma (HCC) tissues. Thus, CXCR4 endothelial cells (ECs) could serve as a potential predictor for patients who may benefit from sorafenib treatment; however, the mechanism that regulates vascular CXCR4 expression in HCC remains largely unknown. Here, we revealed a large number of monocytes/macrophages (Mo/Mϕ) to be selectively enriched in the perivascular areas of CXCR4 vessels in HCC samples.

C-X-C chemokine receptor type 4 (CXCR4) is known to be involved in both developmental and adult angiogenesis; however, its role in tumor angiogenesis remains largely unknown. Here, the role of vascular CXCR4 in regulating vascular structure in hepatocellular carcinoma (HCC) was assessd, and the clinical value of CXCR4 was explored. The expression of CXCR4 in HCC was determined by IHC and immunofluorescence.
