25:T4d4,Calf spleen extractive injection (CSEI), extracted from the spleen of healthy cows (within 24 h of birth), is a small peptides enriched extraction while the ratio between peptide and ribose is 76 ± 15.2 mg/μg. CSEI is usually used as an ancillary agent to assist cancer patients with immune dysfunction. The present study aims to evaluate the immunomodulatory activity of CSEI in cyclophosphamide (CTX)-induced mice model of immunosuppression and its underlying mechanisms. During the experiment, thymosin ɑ1 (0.16 mg/kg) was served as the positive control drug. In CTX-induced immunosuppressed mice, CSEI significantly increased bodyweights and spleen indexes, and upgraded the natural killer activity together with lymphocytes proliferation. CSEI regulated the production of IgG and IgA, and the levels of IL-2, 6, 10, 12 and IFN-ɑ, γ and TNF-ɑ in serum of CTX-induced immunosuppressed mice. Furthermore, CSEI markedly downregulated nuclear factor kappa-B (NF-κB) expression which was controlled by IKKβ. Taken together, CSEI effectively improved immune function in CTX-induced immunosuppression related to NF-κB signalling pathway via regulating the production of immunoglobulins, interleukins and some inflammatory factors.26:T4f6,A series of thiophene derivatives (TPs) were synthesized and evaluated for cytotoxicity in HepG2 and SMMC-7721 cell lines by MTT assay. TP 5 was identified as a potential anticancer agent based on its ability to inhibit tumor cell growth. Drawbacks of TPs, including poor solubility and high toxicity, were overcome through delivery using self-assembling HSA nanoparticles (NPs). The optimum conditions for TP 5-NPs synthesis obtained by adjusting the temperature and concentration of TP 5. The NPs had an encapsulation efficiency of 99.59% and drug-loading capacity of 3.70%. TP 5 was slowly released from TP 5-NPs in vitro over 120 h. HepG2 and SMMC-7721 cell lines were employed to study cytotoxicity of TP 5-NPs, which exhibited high potency. ROS levels were elevated and mitochondrial membrane potentials reversed when the two cell lines were treated with TP 5-NPs for 12 h. Cellular uptake of fluorescence-labeled TP 5-NPs in vitro was analyzed by flow cytometry and laser confocal scanning microscopy. Fluorescence intensity increased over time, suggesting that TP 5-NPs were efficiently taken up by tumor cells. In conclusion, TP 5-NPs showed great promise as an anticancer therapeutic agent.27:T45e,Tricholoma matsutake, one of widely accepted functional mushrooms, possesses various pharmacological activities, and its antitumor effect has become an important research point. Our study aims to evaluate the cytotoxicity activities of T. matsutake aqueous extract (TM) in HepG2 and SMMC-7721 cells. In in vitro experiments, TM strikingly reduced cell viability, promoted cell apoptosis, inhibited cell migration ability, induced excessive generation of ROS, and caused caspases cascade and mitochondrial membrane potential dissipation in hepatocellular carcinoma cells. In in vivo experiments, 14-day TM treatment strongly suppressed tumor growth in HepG2 and SMMC-7721-xenografted nude mice without influence on their body weights and liver function. Furthermore, TM increased the levels of cleaved poly-ADP-ribose polymerase (PARP), Bad, and Bax and reduced the expressions of B-cell lymphoma 2 (Bcl-2) in treated cells and tumor tissues. All aforementioned results suggest that caspase-dependent mitochondrial apoptotic pathways are involved in TM-mediated antihepatocellular carcinoma.28:T659,
