Publications by authors named "Yubo Liang"

This letter comments on the recently published manuscript by Yu , in which the authors revealed a novel mechanism by which the m6A-modified long noncoding RNA kinesin family member 9-antisense RNA 1 promotes stemness and sorafenib resistance of hepatocellular carcinoma (HCC) through ubiquitin-specific peptidase 1-mediated deubiquitination of oncogene short stature homeobox 2. Given the high mortality rate and poor prognosis of HCC, the findings by Yu open a new avenue for overcoming HCC burden by focusing on kinesin family member 9-antisense RNA 1 and short stature homeobox 2 as prognostic markers and therapeutic targets.

Hepatocellular carcinoma (HCC), one of the most prevalent malignant tumors causing the highest mortality globally, imposes an especially heavy burden of disease in China. Individuals living in high-altitude areas have a lower incidence of and mortality resulting from HCC compared with those in low-altitude regions do, potentially due to adaptive evolution in responses to hypoxic stress. Notably, high-altitude hypoxic stress is associated with the development and progression of HCC.

Purpose: This study aimed to investigate whether tumor-associated lymphatic vessel density (LVD) could predict the survival of patients with hepato-biliary-pancreatic (HBP) cancers after radical resection.

Methods: A systematic search was conducted using PubMed, Embase, and Cochrane Library from the inception to July 31, 2024 for literature that reported the role of LVD in overall survival (OS) and recurrence-free survival (RFS) of patients with HBP cancers after radical resection.

Results: Ten studies with 761 patients were included for the meta-analysis.

Article Synopsis
  • Tumor metastasis is a critical issue in the study of malignant tumors, and recent research has begun to explore how nanotechnology can impact this process.
  • Unlike earlier studies that aimed to stop metastasis using nanomaterials, this review focuses on understanding how some nanomaterials might actually promote tumor metastasis through specific mechanisms.
  • Key mechanisms identified include facilitating the transition of tumor cells to a more invasive state, interacting with blood vessels, and inducing inflammation, all of which can enhance metastasis and indicate a need for safer nanomaterial development.

Background: The dominant artery blood supply is a characteristic of hepatocellular carcinoma (HCC). However, it is not known whether the blood supply can predict the post-hepatectomy prognosis of patients with HCC. This retrospective study investigated the prognostic value of the portal venous and arterial blood supply estimated on triphasic liver CT (as a portal venous coefficient, PVC, and hepatic arterial coefficient, HAC, respectively) in patients with HCC following hepatectomy.

Harmful algal blooms (HABs) and their associated phycotoxins are increasing globally, posing great threats to local coastal ecosystems and human health. Nutrients have been carried by the freshwater Yangtze River and have entered the estuary, which was reported to be a biodiversity-rich but HAB-frequent region. Here, in situ solid phase adsorption toxin tracking (SPATT) was used to monitor lipophilic shellfish toxins (LSTs) in seawaters, and extended local similarity analysis (eLSA) was conducted to trace the temporal and special regions of those LSTs in a one-year trail in a mussel culture ranch in the Yangtze River Estuary.

The aim of this study was to investigate the anti-tumor efficacy of brucine on intrahepatic cholangiocarcinoma (ICC). ICC QBC939 cells were treated with brucine, cell viability, cell cycle and apoptosis were analyzed using CCK-8 and flow cytometry. The expression of COX-2 and apoptosis related proteins Casp3, Bax and Bcl-2 were detected by Western blot analysis.

Ag single-atom catalysts (SACs) have great potential in selective electrocatalysis of the CO reduction reaction (CORR) to CO, while it is still a challenge to achieve high current density and high atom efficiency simultaneously. Here, we present a new and simple adsorption-reduction method to prepare Ag SACs supported on CeO (Ag/CeO). It is found that Ag single atoms are anchored on CeO through strong metal-support interaction (SMSI), and each Ag atom is accompanied with three interfacial oxygen vacancies.

Based on the proposed elliptical dielectric fiber-polyethylene gap-3D Dirac semimetal (DSM) hybrid plasmonic waveguide structure, the tunable propagation characteristics have been systematically investigated in the terahertz region, taking into account the influences of the structural parameters, the modified dielectric fiber, and the 3D DSM Fermi levels. The results show that as the ratio of the elliptical semi-axis along the -direction and the -direction (/) increases, the hybrid mode confinement increases. The real part of the effective mode index and propagation length increase with increasing the refractive index of the elliptical fiber.

Marine phycotoxins associated with paralytic shellfish poisoning (PSP), diarrhetic shellfish poisoning (DSP), amnesic shellfish poisoning (ASP), neurotoxic shellfish poisoning (NSP), ciguatera fish poisoning (CFP), tetrodotoxin (TTX), palytoxin (PLTX) and neurotoxin β-N-methylamino-L-alanine (BMAA) have been investigated and routinely monitored along the coast of China. The mouse bioassay for monitoring of marine toxins has been progressively replaced by the enzyme-linked immunosorbent assay (ELISA) and liquid chromatography tandem mass spectrometry (LC-MS/MS), which led to the discovery of many new hydrophilic and lipophilic marine toxins. PSP toxins have been detected in the whole of coastal waters of China, where they are the most serious marine toxins.

Article Synopsis
  • Protoceratium reticulatum is a toxic dinoflagellate with a cyst stage that serves as a crucial paleoenvironmental indicator, showing phenotypic plasticity in its morphology and DNA sequences.
  • Researchers isolated 55 single cysts or cells from various global locations and found that while most strains shared identical LSU rDNA sequences, they differed significantly in ITS rDNA sequences, categorizing them into three distinct ribotypes: A, B, and C.
  • The study revealed that ribotypes exhibited slight variations in growth responses to temperature, with ribotype A from Arctic areas having specific structural differences in its ITS-2 sequences compared to ribotypes B and C, which included temperate and subtropical strains.

Paralytic shellfish toxins (PSTs) are a group of the most harmful neurotoxins distributed worldwide. Marine organism samples, including mollusks, crustaceans and fish, collected from 11 sites around the coastal water of the South China Sea, were analyzed in terms of the PST and toxicity via high-performance liquid chromatography. The PST geographical distribution, detectable rate for PST and toxin content all increased slightly from 2006 to 2008 to 2015.

[Cyclic imine toxin gymnodimine: a review].

Ying Yong Sheng Tai Xue Bao

September 2009

Gymnodimine (GYM), an algal toxin first detected from New Zealand oysters in 1994, is identified as a cyclic imine toxin and produced by Karenia selliformis, with imino nitrogen attached on loop-coil. Imine is the poisonous functional group of the toxin. GYM has a low oral toxicity, but its acute lethal toxicity of intra-peritoneal injection for mice is very high.
