Bulk- and single cell-RNA sequencing reveal KIF20A as a key driver of hepatocellular carcinoma progression and immune evasion.

Introduction: Kinesin family member 20A (KIF20A) is essential for cell proliferation and is implicated in promoting tumor progression, but its role in hepatocellular carcinoma (HCC) remains poorly studied.

Methods: Through the analysis of bulk RNA-sequencing (bulk RNA-seq) and single-cell RNA sequencing (scRNA-seq) data, the expression of KIF20A and its relationship with diagnosis, prognosis, and the immune microenvironment were examined. The association between KIF20A and the malignant progression and metastasis of HCC was confirmed through and experiments.

Nanozyme Decorated Metal-Organic Framework Nanosheet for Enhanced Photodynamic Therapy Against Hypoxic Tumor.

Introduction: Photodynamic therapy (PDT) has attracted increasing attention in the clinical treatment of epidermal and luminal tumors. However, the PDT efficacy in practice is severely impeded by tumor hypoxia and the adverse factors associated with hydrophobic photosensitizers (PSs), including low delivery capacity, poor photoactivity and limited ROS diffusion. In this study, Pt nanozymes decorated two-dimensional (2D) porphyrin metal-organic framework (MOF) nanosheets (PMOF@HA) were fabricated and investigated to conquer the obstacles of PDT against hypoxic tumors.

The Significance of Transarterial Chemo(Embolization) Combined With Tyrosine Kinase Inhibitors and Immune Checkpoint Inhibitors for Unresectable Hepatocellular Carcinoma in the Era of Systemic Therapy: A Systematic Review.

Background And Aims: Regardless of great progress in early detection of hepatocellular carcinoma (HCC), unresectable HCC (uHCC) still accounts for the majority of newly diagnosed HCC with poor prognosis. With the promising results of a double combination of transarterial chemo(embolization) and tyrosine kinase inhibitors (TKIs), and TKIs and immune checkpoint inhibitors (ICIs), a more aggressive strategy, a triple combination of transarterial chemo(embolization), TKIs, and ICIs has been tried in the recent years. Hence, we aimed to conduct a systematic review to verify the safety and efficacy of the triple therapy for uHCC.

A remotely controlled NIR-II photothermal-sensitive transgene system for hepatocellular carcinoma synergistic therapy.

Photothermal therapy (PTT) exhibits an excellent therapeutic effect in cancer treatment, but some cancers are still facing rapid recurrence due to the presence of heat-resistant cells, which express heat shock proteins (HSP) to defend against hyperthermia. Inspired by optogenetics, we firstly designed a caged TNF-related apoptosis-inducing ligand (TRAIL) expressing plasmid under HSP70 protomer (HSP70-TRAIL) as the thermal-activated gene therapy agent to induce the apoptosis of heat resistant cells. Then, the caged HSP70-TRAIL was decorated on the surface of the photothermal agent (semiconducting nanoparticles, SPNs) through electrostatic adsorption to obtain SPN@HSP70-TRAIL-GFP (SPNHT).

A colorimetric sensing platform for azodicarbonamide detection in flour based on MnO nanosheets oxidative system.

Azodicarbonamide (ADA), as a dough conditioner food additive in flour, can be turned into toxic biurea and semicarbazide after high temperature processing. Hence, the using of ADA in food material should be strictly controlled, and the detection of ADA is very important for consumers' safety and health. Herein, a simple and fast colorimetric strategy has been developed for ADA detection based on the MnO nanosheets-3,3',5,5'-tetramethylbenzidine (TMB)-glutathione (GSH) as oxidative sensing system (MnO-TMB-GSH).

Circular RNA CircEPB41L2 Functions as Tumor Suppressor in Hepatocellular Carcinoma Through Sponging miR-590-5p.

Background: Circular RNAs (circRNAs) could interact with miRNAs to regulate gene expression, participating in hepatocellular carcinoma (HCC) initiation and development. This work aimed to determine the potential function and molecular mechanism of circEPB41L2 (hsa_circ_0077837) during HCC progression.

Materials And Methods: The expression of circEPB41L2 in HCC tissues and HCC cell lines was quantified using real-time quantitative PCR (qRT-PCR).

Tumor Microenvironment Triggered Cascade-Activation Nanoplatform for Synergistic and Precise Treatment of Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common and deadliest malignancy cancers, which remains a major global health problem. At present, over 50% of patients with HCC have implemented systemic therapies, such as interventional therapy or local chemotherapy that are scarcely effective and induce serious side effects to the remaining normal liver, further limiting their clinical outcomes. Herein, a tumor microenvironment triggered cascade-activation nanoplatform (A-NP ) is prepared based on β-lapachone (β-Lap) and tirapazamine (TPZ) for the synergistic therapy of HCC.

A thieno-isoindigo derivative-based conjugated polymer nanoparticle for photothermal therapy in the NIR-II bio-window.

Photothermal therapy (PTT), a powerful tool for non-invasive cancer treatment, has been recognized as an alternative strategy for cancer therapy in the clinic, and it is promoted by optical absorbing agents (photothermal agents) that can intensively convert near-infrared (NIR) light into thermal energy for cancer ablation. Conjugated polymer nanoparticles (CPNs) have recently attracted extensive attention owing to their excellent photothermal properties. However, the absorption of typical CPNs is mostly located in the traditional near-infrared region (NIR-I, 700-900 nm), which suffers from low tissue penetration, so the penetration depth is still limited and severely restricts their further applications.

Photodynamic Therapy Combined with Antihypoxic Signaling and CpG Adjuvant as an In Situ Tumor Vaccine Based on Metal-Organic Framework Nanoparticles to Boost Cancer Immunotherapy.

Photodynamic therapy (PDT) usually aggravates tumor hypoxia, which promotes the survival and metastasis of residue cancer cells; furthermore, although PDT-induced immunogenic death of cancer cells can induce host antitumor responses, such responses are generally weak and not enough to eliminate the residue cancer cells. Here, metal-organic framework (MOF)-based nanoparticles to combine PDT, antihypoxic signaling, and CpG adjuvant as an in situ tumor vaccine to boost host anticancer responses after PDT are designed. The MOF-based nanoparticles are self-assembled from H TCPP and zirconium ions with hypoxia inducible factor (HIF) signaling inhibitor (ACF) and immunologic adjuvant (CpG) loading, and hyaluronic acid (HA) coating on the surface.

A systematic review of the comparison of the incidence of seeding metastasis between endoscopic biliary drainage and percutaneous transhepatic biliary drainage for resectable malignant biliary obstruction.

Background And Aim: Endoscopic biliary drainage (EBD) and percutaneous biliary drainage (PTBD) are the two main strategies of preoperative biliary drainage (PBD) for resectable malignant biliary obstruction (MBO) worldwide, but which is better remains unclear. Seeding metastasis (SM) has been reported repeatedly in the recent decade, although it is rarely taken into consideration in the choice of PBD. Hence, a systematic review was badly warranted to evaluate the incidence of SM between PTBD and EBD in the preoperative treatment of MBO.
