Clear cell renal cell carcinoma (ccRCC) is one of the most common malignancies. Recently, the role of brain-expressed X-linked 4 (BEX4) in cancer progression has received increasing attention. This study aimed to investigate the function of BEX4 in ccRCC and to reveal the underlying mechanisms.

The T cell-mediated tumor killing patterns revealed tumor heterogeneous and proposed treatment recommendation in ovary cancer.

Background: Immune checkpoint inhibitors (ICIs) have greatly improved cancer treatment, but the role of genes related to T cell-mediated tumor killing (TTK) sensitivity in ovarian cancer (OV) is unclear.

Methods: This study analyzed 1367 OV patients and 11 independent cohorts. The unsupervised clustering was conducted to identify three tumor subtypes based on genes that regulate tumor cell sensitivity to TTK (GSTTKs).

Interpretable multi-modal artificial intelligence model for predicting gastric cancer response to neoadjuvant chemotherapy.

Neoadjuvant chemotherapy assessment is imperative for prognostication and clinical management of locally advanced gastric cancer. We propose an incremental supervised contrastive learning model (iSCLM), an interpretable artificial intelligence framework integrating pretreatment CT scans and H&E-stained biopsy images, for improved decision-making regarding neoadjuvant chemotherapy. We have constructed and tested iSCLM using retrospective data from 2,387 patients across 10 medical centers and evaluated its discriminative ability in a prospective cohort (132 patients; ChiCTR2300068917).

Efficacy and Safety of KH903 Plus FOLFIRI as a Second-Line Treatment in Unresectable Recurrent or Metastatic Colorectal Cancer: A Randomized Phase 2 Study.

Background: Patients with recurrent or metastatic advanced colorectal cancer (mCRC) often face the clinical dilemma as this unresectable disease is continuously progressing and endangering the patients' lives. In the current study, we explored the clinical feasibility of KH903 in combination with FOLFIRI chemotherapy as a new clinical indication for mCRC.

Methods: Patients (N = 122) were randomized 1:1 to 4mg/kg q1w KH903 or 5mg/kg q2w KH903, and both groups of patients were treated with the fixed regimen of FOLFIRI (every 2 weeks) along with the KH903 therapy.

A Novel "Three-in-One" Copper-Based Metal-Organic Framework Nanozyme Eradicates Colorectal Cancer and Overcomes Chemoresistance for Tumor Therapy.

Despite considerable advancements in the treatment of colorectal cancer (CRC), the overall survival rate for patients with advanced CRC remains below 50%, primarily due to challenges posed by drug resistance and metastasis. Here, a novel "Three-in-One" Cu-based metal-organic framework nanozyme with peroxidase-like (POD-like) activity has been successfully developed, aiming to promote CRC cell death by dual targeting of oxidative stress and copper ion homeostasis, which could promote CRC cell death via apoptosis and cuproptosis, and facilitate hypoxia-inducible factor 1α (HIF-1α) degradation, leading to the reversal of chemoresistance in tumor therapy. These nanozymes, composed of copper and 2-propylimidazole (Cu-PrIm), feature a distorted Cu-N4 catalytic active center that mimics natural enzyme structures consisting of copper and histidine residues, endowing them with enzyme-like activities.

Adenosine signaling in tumor-associated macrophages and targeting adenosine signaling for cancer therapy.

This review examined the critical role of adenosine signaling in modulating the behavior of tumor-associated macrophages (TAMs), a key determinant of the tumor microenvironment (TME). Adenosine is an immunosuppressive metabolite that is highly enriched in the TME due to elevated expression of adenosine triphosphatase (ATPase). Adenosine influences polarization of TAMs through A2A and A2B receptors, which drives a phenotype that supports tumor progression and immune evasion.

Inaticabtagene Autoleucel (CNCT19) in adult relapsed or refractory B-cell acute lymphoblastic leukemia.

Prior to November 2023, CD19 CAR-T therapies had not been approved in China for patients with relapsed or refractory B-cell acute lymphoblastic leukemia (r/r B-ALL), leaving a significant unmet need. In response, Inaticabtagene Autoleucel (Inati-cel), a novel CD19 CAR-T therapy with a distinct scFv (HI19α), was developed and showed promising efficacy in preliminary clinical research. We conducted a phase 2, single-arm, multicenter study of Inati-cel in adult CD19+ r/r B-ALL in China.

Intrathecal tocilizumab for immune-mediated central nervous system complication after haploidentical hematopoietic stem cell transplantation in children: Two case reports.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective measure for the treatment of hematological disease. With the progress and wide use of allo-HSCT, post-transplant central nervous system complications (CNSC) have gotten more and more attention because of its poor prognosis and high mortality. Since there is no standard treatment for patients with immune-mediated CNSC currently, new treatments are needed to be developed urgently.
