ABSTRACT

PD-1 and PD-L1 antibodies have brought about extraordinary clinical benefits for cancer patients, and their indications are expanding incessantly. Currently, most PD-1/PD-L1 agents are administered intravenously, which may be uncomfortable for some cancer patients. Herein, we develop a novel oral-delivered small molecular, YPD-29B, which specifically targets human PD-L1. Our data suggested that YPD-29B could potently and selectively block the interaction between PD-L1 and PD-1, but did not inhibit any other immune checkpoints. Mechanistically, YPD-29B induced human PD-L1 dimerization and internalization, which subsequently activated T lymphocytes and therefore overcomes immunity tolerance in vitro. YDP-29B was modified as the YPD-30 prodrug to improve druggability. Using humanized mice with human PD-1 xenografts of human PD-L1 knock-in mouse MC38 cancer cells, we demonstrated that YPD-30 exhibited significant antitumor activity and was well tolerated in vivo. Taken together, our results indicate that YPD-30 serves as a promising therapeutic candidate for anti-human PD-L1 cancer immunotherapy.

ABSTRACT

Glioblastoma is carcinogenesis of glial cells in central nervous system and has the highest incidence among primary brain tumors. Brain metastasis, such as breast cancer and lung cancer, also leads to high mortality. The available medicines are limited due to blood-brain barrier. Abnormal activation of phosphatidylinositol 3-kinases (PI3K) signaling pathway is prevalent in glioblastoma and metastatic tumors. Here, we characterized a 2-amino-4-methylquinazoline derivative XH30 as a potent PI3K inhibitor with excellent anti-tumor activity against human glioblastoma. XH30 significantly repressed the proliferation of various brain cancer cells and decreased the phosphorylation of key proteins of PI3K signaling pathway, induced cell cycle arrest in G1 phase as well. Additionally, XH30 inhibited the migration of glioma cells and blocked the activation of PI3K pathway by interleukin-17A (IL-17A), which increased the migration of U87MG. Oral administration of XH30 significantly suppressed the tumor growth in both subcutaneous and orthotopic tumor models. XH30 also repressed tumor growth in brain metastasis models of lung cancers. Moreover, XH30 reduced IL-17A and its receptor IL-17RA in vivo. These results indicate that XH30 might be a potential therapeutic drug candidate for glioblastoma migration and brain metastasis.

ABSTRACT

Enormous studies have corroborated that long non-coding RNAs (lncRNAs) extensively participate in crucial physiological processes such as metabolism and immunity, and are closely related to the occurrence and development of tumors, cardiovascular diseases, nervous system disorders, nephropathy, and other diseases. The application of lncRNAs as biomarkers or intervention targets can provide new insights into the diagnosis and treatment of diseases. This paper has focused on the emerging research into lncRNAs as pharmacological targets and has reviewed the transition of lncRNAs from the role of disease coding to acting as drug candidates, including the current status and progress in preclinical research. Cutting-edge strategies for lncRNA modulation have been summarized, including the sources of lncRNA-related drugs, such as genetic technology and small-molecule compounds, and related delivery methods. The current progress of clinical trials of lncRNA-targeting drugs is also discussed. This information will form a latest updated reference for research and development of lncRNA-based drugs.

ABSTRACT

Psoriasis is characterized by abnormal proliferation of keratinocytes, as well as infiltration of immune cells into the dermis and epidermis, causing itchy, scaly and erythematous plaques of skin. The understanding of this chronic inflammatory skin disease remains unclear and all available treatments have their limitations currently. Here, we showed that IMMH002, a novel orally active S1P modulator, desensitized peripheral pathogenic lymphocytes to egress signal from secondary lymphoid organs and thymus. Using different psoriasis animal models, we demonstrated that IMMH002 could significantly relieve skin damage as revealed by PASI score and pathological injure evaluation. Mechanistically, IMMH002 regulated CD3 T lymphocytes re-distribution by inducing lymphocytes' homing, thus decreased T lymphocytes allocation in the peripheral blood and skin but increased in the thymus. Our results suggest that the novel S1P agonist, IMMH002, exert extraordinary capacity to rapidly modulate T lymphocytes distribution, representing a promising drug candidate for psoriasis treatment.

ABSTRACT

Objective To investigate the morphological changes of the brainstem in patients with Alzheimer's disease (AD) and their relationship with hippocampal morphological changes.Methods Sixty AD patients (AD group) and sixty age-and gender-matched normal elderly (normal control group) were selected from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database.The hippocampus and the brainstem of each subject were segmented and their normalized volumes were calculated.According to the hippocampal volume standard value (Z-score),AD patients were divided into two subgroups (hippocampal atrophy group (n=51) and hippocampal spared group (n=9)).A voxel-based morphology (VBM) study was also performed to investigate the morphological differences of the brainstem between the normal control group and the AD group,as well as between the AD subgroups.Results Compared with the normal control group,the brainstem volume in the AD group decreased significantly (16 741.31±1 739.11 vs 15 609.67±1 451.60,t=3.870,P=0.001).In AD subgroups,the volume of the brainstem in the hippocampal atrophy group was significantly smaller than that in the hippocampal spared group (16 556.30 ± 1 514.86 vs 15 442.62 ± 1 389.05,t=2.189,P=0.033).Pearson correlation analysis showed that Mini-Mental State Examination scores were positively correlated with the hippocampal and the brainstem volumes (r=0.590,P<0.01;r=0.234,P<0.05),and there was a positive correlation between the hippocampal and the brainstem volume changes in patients with AD (r=0.315,P=0.014).VBM results showed that both the bilateral midbrain and the bilateral pons in the AD group had significant atrophy compared with the normal control group (P<0.05).In the AD subgroups,the bilateral midbrain and the left pons in the hippocampal atrophy group were significantly atrophied compared with the hippocampal spared group (P<0.05).Conclusion The brainstem showed morphological changes in patients with AD,and the morphological changes of the brainstem in AD patients with different degrees of hippocampal atrophy were different,indicating the morphological changes of the hippocampus and the brainstem may have an interrelated relationship.

ABSTRACT

Objective: Today, esophageal cancer [EC] has become one of the most common cancer types in China. Therefore, new drug and therapeutic strategies are urgently needed to improve postoperative survival rate of patients with EC. As a food additive, several lines of evidence have shown that citric acid can be served as glycolysis suppressor to inhibit growth of some tumor cells. However, little is known about the effect of this organic acid on the growth of human esophageal carcinoma cell line, EC109


Materials and Methods: In this experimental study, cell proliferation rate was determined using MTT assay. Apoptotic morphological changes were evaluated by fluorescent microscopy using Hoechst 33258 staining. Cell apoptosis rate and mitochondrial membrane potential [MMP] were detected using flow-cytometry. Effect of citric acid on cellular membrane permeability was assessed by measuring lactate dehydrogenase [LDH] activity, using LDH assay kit


Results: Compared to the control group, there was a marked decrease in cells proliferation when the cells were treated with higher citric acid concentrations [800, 1600 micro g/ml]. Typical apoptotic morphology of EC109 cells was observed upon treatment with citric acid, such as chromatin condensation and appearance of apoptotic body. Cell apoptotic indexes were significantly increased [P<0.01] after treatment with citric acid at the concentration of 400-1600 micro g/ml. Extracellular LDH activity and loss of MMP in all of the treated groups were significantly higher than control [P<0.05], in a dose-dependent manner


Conclusion: These results suggest that citric acid prevents EC109 cell growth by inhibiting cell proliferation and inducing apoptosis, which perhaps offers some theoretical guidance for its application in EC treatment
