Advanced biliary tract cancer (BTC) and pancreatic ductal adenocarcinoma (PDAC) have poor prognoses and limited treatment options. Here, we conducted this first-in-class phase II study to evaluate the efficacy and safety of SHR-1701, a bifunctional fusion protein targeting programmed death-ligand 1 (PD-L1) and transforming growth factor-beta (TGF-β), combined with famitinib, a multi-targeted receptor tyrosine kinase inhibitor, in patients with advanced BTC or PDAC who failed previous standard treatment (trial registration: ChiCTR2000037927). Among 51 enrolled patients, the BTC cohort showed an objective response rate (ORR) of 28% (including 2 complete responses) and a disease control rate (DCR) of 80%, with a median progression-free survival (mPFS) of 5.

Biological materials dynamically reconfigure their underlying structures in response to stimuli, achieving adaptability and multifunctionality. Conversely, mechanical metamaterials have fixed interunit connections that restrict adaptability and reconfiguration. This study introduces granular metamaterials composed of discrete bimaterial structured particles that transition between assembled and unassembled states through mechanical compression and thermal stimuli.

Article Synopsis
  • * Analysis of 34,775 samples revealed 29,051 tumor-specific transcripts (TSTs) that are mostly unannotated, correlating with tumor stemness and poor patient outcomes.
  • * TSTs may hint at new cancer treatments, as they can produce neoantigens for immunotherapy and are detectable in blood extracellular vesicles from cancer patients.

Mechanical metamaterials for energy dissipation have received significant attention for vibration and impact mitigation. However, existing designs often neglect energy dissipation in the tensile direction, which is crucial for attenuating tensile load and controlling falling descent. Importantly, current energy-dissipating mechanisms including plastic deformation and friction mechanisms, suffer from drawbacks such as reversibility and self-recovery, restricting their effectiveness under tension.

  • Tumor cells adapt their gene expression to create an environment that supports their growth and aggressive traits, but the key regulatory factors behind this process remain unclear.
  • Researchers utilized single-cell RNA sequencing and animal models to investigate liver cancer, discovering that liver tumors reorganize an oncofetal ecosystem to retain malignant characteristics.
  • A specific RNA-binding protein called TRIM71 was found to be overexpressed in liver cancers and linked to poor patient outcomes, and targeting TRIM71 with certain treatments showed potential for inhibiting cancer cell growth.

  • Sitravatinib is a targeted treatment for advanced cancers, specifically focusing on TAM receptors and others, and was tested in a study (SAFFRON-104) for its effectiveness alone or with another drug (tislelizumab) in advanced liver or stomach cancers.
  • The study included 111 patients, and the recommended dosage of sitravatinib was established at 120 mg daily. Results showed that about 25% of patients experienced a positive response to sitravatinib alone, while those receiving it with tislelizumab had lower response rates.
  • Overall, the combination of sitravatinib and tislelizumab was generally safe with manageable side effects, indicating preliminary

Background: Advanced pancreatic adenocarcinoma lacks effective treatment options, and systemic gemcitabine-based chemotherapy offers only marginal survival benefits at the cost of significant toxicities and adverse events. New therapeutic options with better drug availability are warranted. This study aims to evaluate the safety and efficacy of digital subtraction angiography (DSA)-guided pancreatic arterial infusion (PAI) versus intravenous chemotherapy (IVC) using the gemcitabine and oxaliplatin (GEMOX) regimen in unresectable locally advanced or metastatic pancreatic cancer (PC) patients.

The potential long-term effects of anesthesia on cognitive development, especially in neonates and infants, have raised concerns. However, our understanding of its underlying mechanisms and effective treatments is still limited. In this study, we found that early exposure to isoflurane (ISO) impaired fear memory retrieval, which was reversed by dexmedetomidine (DEX) pre-treatment.

The organ-specific toxicity resulting from microplastic (MP) exposure has been extensively explored, particularly concerning the gut, liver, testis, and lung. However, under natural conditions, these effects are not restricted to specific organs or tissues. Investigating whether MP exposure presents a systemic threat to an entire organism, impacting factors such as lifespan, sleep, and fecundity, is essential.

Neoantigen-based therapy is a promising approach that selectively activates the immune system of the host to recognize and eradicate cancer cells. Preliminary clinical trials have validated the feasibility, safety, and immunogenicity of personalized neoantigen-directed vaccines, enhancing their effectiveness and broad applicability in immunotherapy. While many ongoing oncological trials concentrate on neoantigens derived from mutations, these targets do not consistently provoke an immune response in all patients harboring the mutations.

Introduction: Hepatitis B Virus (HBV) is widely recognized as a "metabolic virus" that disrupts hepatic metabolic homeostasis, rendering it one of the foremost risk factors for hepatocellular carcinoma (HCC). Except for antiviral therapy, the fundamental principles underlying HBV and HBV HCC have remained unchanged, limiting HCC treatment options.

Objectives: In this study, we aim to identify the distinctive metabolic profile of HBV-associated HCC, with the promise of identifying novel metabolic targets that confer survival advantages and ultimately impede cancer progression.

Malignant ascites is a common complication resulting from the peritoneal spread of malignancies, and currently lacks effective treatments. We conducted a phase II trial (NCT04771676) to investigate the efficacy and safety of oncolytic adenovirus H101 and virotherapy-induced immune response in 25 patients with malignant ascites. Oncolytic virotherapy achieved an increased median time to repeat paracentesis of 45 days (95% confidence interval 16.

Metamaterials composed of different geometrical primitives have different properties. Corresponding to the fundamental geometrical forms of line, plane, and surface, beam-, plate-, and shell-based lattice metamaterials enjoy many advantages in many aspects, respectively. To fully exploit the advantages of each structural archetype, we propose a multilayer strategy and topology optimization technique to design lattice metamaterial in this study.

Biliary tract cancer (BTC) is an aggressive malignancy with few options for advanced-stage treatment. The combination of PD-1/PD-L1 inhibitors with famitinib, a receptor tyrosine kinase (RTK) inhibitor, has demonstrated improved clinical outcomes in several clinical trials. We herein reported a case of a gallbladder cancer (GBC) patient with liver metastases, previously resistant to traditional chemotherapy.

Background: The low response rate of immune checkpoint inhibitors (ICIs) prompts the exploration of novel combination therapies for patients with hepatocellular carcinoma (HCC). Here, we aimed to examine the efficiency and potential mechanism of cryo-thermal ablation (Cryo-A) combined with anti-programmed death protein 1 (αPD1) and/or cytotoxic T-lymphocyte antigen 4 (αCTLA4) inhibitors in a murine hepatoma model.

Method: Immunocompetent C57BL/6 mice inoculated with unilateral or bilateral H22 hepatic tumour cells were treated with Cryo-A and/or ICIs (αPD1 and/or αCTLA4).

Sleep disturbances are associated with poor long-term memory (LTM) formation, yet the underlying cell types and neural circuits involved have not been fully decoded. Dopamine neurons (DANs) are involved in memory processing at multiple stages. Here, using both male and female flies, , we show that, during the first few hours of memory consolidation, disruption of basal activity of a small subset of protocerebral anterior medial DANs (PAM-DANs), by either brief activation or inhibition of the two dorsal posterior medial (DPM) neurons, impairs 24 h LTM.

No well-established biomarkers are available for the clinical diagnosis of major depressive disorder (MDD). Vitamin D-binding protein (VDBP) is altered in plasma and postmortem dorsolateral prefrontal cortex (DLPFC) tissues of MDD patients. Thereby, the role of VDBP as a potential biomarker of MDD diagnosis was further assessed.
