Introduction: So far, anti-PD-1/anti-PD-L1 antibody therapy is reportedly in treating gastric cancer or gastro-oesophageal junction cancer (GC/GEJC) in a number of clinical trials. Based on this, we conducted current meta-analysis to assess the safety and efficacy of anti-PD-1/anti-PD-L1 antibody for previously treated advanced GC/GEJC patients.
Methods: We searched five electronic databases for eligible records. Outcomes were presented and analyzed by objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and adverse effects (AEs).
Results: Nine records involving 1388 participants were selected in our study. The pooled ORR, DCR, OS rate (6 month), PFS rate (6 month), OS rate (12 month) and PFS rate (12 month) were 10% (95% confidence interval [CI]: 6%-14%), 32% (95%CI: 25%-38%), 52% (95%CI: 44%-61%), 18% (95%CI: 13%-24%), 40% (95%CI: 31%-48%) and 8% (95%CI: 5%-10%), respectively. Meanwhile, grade≥3 AEs rate was 12% (95% CI: 10%-15%). Programmed death ligand 1 (PD-L1) positive cases had higher rate of ORR (odds ratio [OR]: 3.75, 95%CI: 2.09-6.74, P=0.58) compared with negative cases.
Conclusion: The results indicated that anti-PD-1/anti-PD-L1 antibody therapy has an effectual anti-tumor activity and controllable AEs in advanced GC/GEJC patients. Furthermore, overexpression of PD-L1 in advanced GC/GEJC patients had better ORR from anti-PD-1/anti-PD-L1 antibody therapy (PROSPERO registration number: CRD42018116480).

Immune checkpoints inhibitors (ICIs) as anti-PD-1/anti-PD-L1 have been approved as first-line treatment in patients with non-small cell lung cancer (NSCLC), but only 25 % of patients achieve durable response. We previously unveiled that estrogen receptor α transcriptionally up-regulates PD-L1 and aromatase inhibitors such as letrozole increase the efficacy of pembrolizumab. Here we investigated if letrozole may have additional immune-sensitizing mechanisms.

Approximatively 80% of kidney cancers globally are clear cell kidney cancers (ccRCCs), with 80% of these malignancies featuring an inactivating mutation of the Von Hippel-Lindau gene. This genetic alteration leads to the stabilization of hypoxia inducible factors 1 and 2 alpha (HIF 1 and 2α), resulting in the over-expression of target genes such as vascular endothelial growth factor (VEGF), which is crucial for angiogenesis. As a result, ccRCCs are highly vascularized and serve as models for anti-angiogenic treatments (AAT).

The precise regulation of protein function is essential in biological systems and a key goal in chemical biology and protein engineering. Here, we describe a straightforward method to engineer functional control into the isopeptide bond-forming SpyTag/SpyCatcher protein ligation system. First, we perform a cysteine scan of the structured region of SpyCatcher.

Immune checkpoint inhibitors (ICIs), including anti-PD-1, anti-PD-L1 and anti-CTLA-4 antibodies, have become a standard treatment for multiple cancer types. However, ICIs can induce immune-related adverse events, with hepatitis-related adverse events (HRAEs) being of particular concern. Our objective is to identify and characterize HRAEs that exhibit a significant association with ICIs using real-world data.

The immune system plays a pivotal role in the battle against cancer, serving as a formidable guardian in the ongoing fight against malignant cells. To combat these malignant cells, immunotherapy has emerged as a prevalent approach leveraging antibodies and peptides such as anti-PD-1, anti-PD-L1, and anti-CTLA-4 to inhibit immune checkpoints and activate T lymphocytes. The optimization of gut microbiota plays a significant role in modulating the defense system in the body.
