AI Article Synopsis

  • The polysaccharide LBPP was extracted from brassica napus L. pollen and tested for its antitumor effects on mice with Sarcoma 180 and B16 melanoma through a 10-day treatment.
  • Mice were given three different doses (50, 100, and 200 mg/kg) of LBPP, and various health measures like tumor weight and immune system responses were evaluated.
  • Higher doses (100 and 200 mg/kg) showed significant decreases in tumor growth and improvements in immune functions and blood conditions, indicating LBPP's potential as an effective anti-tumor agent through its ability to modulate the immune system.

Article Abstract

The polysaccharide LBPP was extracted and isolated from the pollen of brassica napus L., and the antitumor activity was evaluated on Sarcoma 180-bearing mice and B16 melanoma-bearing mice through transplantable animal tumor. Mice were treated with three doses of the polysaccharide LBPP (50, 100 and 200 mg/kg body weight) for 10 days. Tumor weight, relative spleen and thymus weight, lymphocyte proliferation, natural killer cell activity, delayed type hypersensitivity (DTH), phagocytic function of monocyte, serum hemolysis antibody and peripheral blood of tumor-bearing mice were studied. At the doses of 100 and 200 mg/kg, a significant decrease (P<0.01) in tumor formation, a significant increase (P<0.05) in relative spleen and thymus weight, natural killer cell activity, phagocytic function of monocyte, lymphocyte proliferation, and serum hemolysis antibody, and a significant improvement of peripheral blood abnormality (P<0.05) and anemia (P<0.01) were observed. Results of these studies demonstrated that the polysaccharide LBPP had anti-tumor activity, which was mediated by immunomodulation and leukogenic and antianemic actions.

Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer with limited treatment options and a poor prognosis. The critical role of epigenetic alterations such as changes in DNA methylation, histones modifications, and chromatin remodeling, in pancreatic tumors progression is becoming increasingly recognized. Moreover, in PDAC these aberrant epigenetic mechanisms can also limit therapy efficacy.

Chimeric antigen receptor with novel intracellular modules improves antitumor performance of T cells.

The excessive cytokine release and limited persistence represent major challenges for chimeric antigen receptor T (CAR-T) cell therapy in diverse tumors. Conventional CARs employ an intracellular domain (ICD) from the ζ subunit of CD3 as a signaling module, and it is largely unknown how alternative CD3 chains potentially contribute to CAR design. Here, we obtained a series of CAR-T cells against HER2 and mesothelin using a domain comprising a single immunoreceptor tyrosine-based activation motif from different CD3 subunits as the ICD of CARs.

To evaluate the long-term clinical outcomes of iodine-125 low dose-rate brachytherapy (LDR-BT)-based treatment approaches for ≤ cT3 prostate cancer (PC) patients in China, as well as the effects on the PC immune microenvironment. Data was retrospectively collected from 237 patients with ≤ cT3 PC who were treated with radical prostatectomy (RP) or LDR-BT alone or in combination with androgen deprivation therapy (ADT), and biochemical progression-free survival (bPFS), prostate cancer-specific survival (PCSS) and overall survival (OS) rates were compared. In 63 cases, PC patients received RP after biopsy, received at least 6 months of ADT before RP, or received LDR-BT and deferred limited transurethral resection of the prostate (TURP).

Glioblastoma multiforme (GBM) is characterized by pronounced immune escape and resistance to chemotherapy-induced apoptosis. Preliminary investigations revealed a marked overexpression of gasdermin E (GSDME) in GBM. Notably, cisplatin (CDDP) demonstrated a capacity of inducing pyroptosis by activating caspase-3 to cleave GSDME, coupled with the release of proinflammatory factors, indicating the potential as a viable approach of inducing anti-tumor immune activation.

Developing effective nanoplatforms for chemo-immunotherapy to achieve enhanced tumor suppression and systemic antitumor immunity has recently received extensive attention. Herein, we formulated a multifunctional DNA sandwich nanodevice, DSWAC/siPD-L1, based on triangular DNA origami, to implement enhanced cancer chemo-immunotherapy. Taking advantage of the tumor-targeting ability of the AS1411 aptamer, DSWAC/siPD-L1 efficiently delivered doxorubicin (DOX), CpG, and siPD-L1 into tumor cells.
