Cancer Lett

January 2025

Advanced Medical Research Institute, Qilu College of Medicine, Shandong University, Jinan, 250012, China. Electronic address:

Dysregulated lipid metabolism is linked to tumor progression. In this study, we identified Niemann-Pick C1-like 1 (NPC1L1) as a downstream effector of PKM2. In breast cancer cells, PKM2 knockout (KO) enhanced NPC1L1 expression while downregulating peroxisome proliferator-activated receptor α (PPARα) signaling pathway.

Simultaneous Induction of Immunogenic Pyroptosis and PD-L1 Downregulation by One Single Photosensitizer for Synergistic Cancer Photoimmunotherapy.

J Med Chem

January 2025

Department of Medicinal Chemistry, Key Laboratory of Chemical Biology (Ministry of Education), School of Pharmaceutical Sciences, Cheeloo College of Medicine, Shandong University, Jinan, Shandong 250012, P. R. China.

Pyroptosis, an excellent form of immunogenic cell death that can effectively activate antitumor immune responses, is attracting considerable interest as a promising approach for cancer immunotherapy. Immunogenic pyroptosis can recruit and stimulate dendritic cells to provoke further activation and tumor infiltration of T cells by releasing danger-associated molecular patterns, thus improving the tumor response to PD-1/PD-L1 checkpoint blockade immunotherapy. Here, we report the discovery of a bifunctional photosensitizer Nile Violet that can simultaneously trigger caspase-3/GSDME-mediated immunogenic pyroptosis and PD-L1 downregulation for cancer photoimmunotherapy.

Department of Dermatology, Affiliated Hospital of Shandong University of Traditional Chinese Medicine, Shandong Provincial Hospital of Traditional Chinese Medicine, The First Clinical Medical College of Shandong University of Traditional Chinese Medicine, Jinan, 250011, China.

Wogonin is a compound extracted from the medicinal plant Scutellaria baicalensis Geogi and has been found to exert antitumor activities in a variety of malignancies. However, the molecular mechanisms involved in the anti-gastric cancer (GC) effects of wogonin remain poorly understood. In the present study, we found that wogonin treatment inhibited the proliferation of GC cells, induced apoptosis and G0/G1 cell arrest, and suppressed the migration and invasion of SGC-7901 and BGC-823 cells in vitro.

Epidemiological studies and a recent Mendelian randomization (MR) study have identified an association between low bone mass and an increased risk of scoliosis. Previous research suggests that bone loss in patients with scoliosis may be related to the RANK-RANKL-OPG system. This study is to investigate whether a causal relationship exists between the RANK-RANKL-OPG system and the development of scoliosis.

Identification of host proteins that interact with African swine fever virus pE301R.

State Key Laboratory of Microbial Technology, Microbial Technology Institute, Shandong University, Qingdao 266237, China.

African swine fever virus (ASFV) infection poses enormous threats and challenges to the global pig industry; however, no effective vaccine is available against ASFV, attributing to the huge viral genome (approximately189 kb) and numerous encoding products (>150 genes) due to the limited understanding on the molecular mechanisms of viral pathogenesis. Elucidating the host-factor/viral-protein interaction network will reveal new targets for developing novel antiviral therapies. Using proteomic analysis, we identified 255 cellular proteins that interact with the ASFV-encoded pE301R protein when transiently expressed in HEK293T cells.

The therapeutic potential of commensal microbes and their metabolites is promising in the functional cure of chronic hepatitis B virus (HBV) infection, which is defined as hepatitis B surface antigen (HBsAg) loss. Here, using both specific-pathogen-free and germ-free mice, we report that probiotics significantly promote the decline of HBsAg and inhibit HBV replication by enhancing intestinal homeostasis and provoking intrahepatic interferon (IFN)-γCD4 T cell immune response. Depletion of CD4 T cells or blockage of IFN-γ abolishes probiotics-mediated HBV inhibition.

The leading cause of cancer-related death among female patients is breast cancer. Among all the types of breast cancer, triple-negative breast cancer (TNBC) is the most dangerous molecular subtype of breast cancer characterized by the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) expression. Since there is no particular therapeutic strategy for TNBC that has been shown to worsen the disease prognosis, 3D models are superior to 2D models as a predictive tool for drug discovery because they more accurately reflect the in vivo biological components of humans.

Due to the uncertain differentiation of neural stem cells (NSCs), replenishing lost neurons by endogenous neural differentiation to repair spinal cord injury (SCI) remains challenging. The electrical stimulation-induced drug release is a promising approach for the localized and controlled release of drugs to regulate the differentiation of NSCs into neurons. Here, we developed Zn-PDA@BT nanoparticles acted as Trojan Horse to enter cells through endocytosis for Zn-controlled release therapy by the potentials generated by the piezoelectric effect.
