To explore the protective efficacies and potent mechanism of amygdalin on high glucose-cultured renal cell HBZY-1 in vitro and streptozotocin (STZ)-induced diabetic nephropathy (DN) rat in vivo.
The cellar proliferation and generation of ROS in high-glucose cultured HBZY-1 cell were assessed by MTT and DCFH-DA assay, respectively. The fasting blood glucose levels, renal function and inflammation indexes as well as oxidative stress markers in STZ-induced diabetic rats were all measured. The histologic renal section was stained with Mason and periodic acid-Schiff (PAS) method. Immunohistochemistry and western blotting methods were applied to assess expression levels of extracellular matrix (ECM), epithelial-mesenchymal transition (EMT)-related as well as TGF-β1/Smad signaling pathway-related proteins.
Firstly, amygdalin significantly suppressed the excessive cell proliferation and ROS generation in HBZY-1 cells cultured with high glucose. The hyperglycemia, 24h-UP excretion, BUN and Scr of DN rats were significantly attenuated after the chronic treatment of amygdalin. Moreover, MDA, SOD, IFN-γ and IL-12 levels in kidney tissues were all effectively reduced. Besides, amygdalin can suppress the ECM accumulation and EMT transformation by inhibiting Smad/TGF-β pathway to alleviate the renal fibrosis in renal tissues of DN model rats.
Amygdalin ameliorates excessive oxidative stress, inflammation and renal tissue fibrosis of DN mainly by suppressing TGF-β1/Smad signaling pathway and regulating the key enzymes of ECM degradation.

In this review, we summarized the mechanisms underlying the protective effects of AMPK activation against obesity-related renal injury in preclinical studies, with the main purposes of increasing the understanding of AMPK and providing new insights into the future clinical therapeutic strategies. The renoprotective effects of AMPK mainly act by modulating lipid metabolism and autophagy and suppressing oxidative stress, inflammation, and fibrosis. More importantly, we discussed the recent advances in this field that require further investigation. Firstly, the inhibitory effect of AMPK on ferroptosis is a potential mechanism for its protection against renal injury. Secondly, the effect of AMPK on lipolysis is complex AMPK induces basal lipolysis but also inhibits stimulated lipolysis. Thirdly, statins may play a renoprotective role by activating AMPK. Fourthly, some microRNAs targeting AMPK mRNA have been implicated in diabetic nephropathy in type 2 diabetes. Further, AMPK can regulate the expression of some microRNAs, suggesting that the stable renoprotective effects of AMPK may benefit from its epigenetic regulation. Lastly, several natural compounds and synthetic drugs have been recognized to protect against obesity-related renal injury by activating AMPK and its downstream pathways in animal models. It remains to be seen if combination of newly identified drugs with traditional renoprotective medicine will have any synergistic therapeutic benefits without adding to side effects.
Previous studies demonstrated that H
S has an antihypertension effect on hypertension, but the mechanism involved is unclear until now. The aim of the study is to elucidate the effect of H
S on PH and the mechanism involved.
In this study, GYY4137 (a H
S donor) were administered to spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY) by intraperitoneally injection daily for consecutive 14days. Systolic blood pressure (SBP), endothelial-dependent relaxation (EDR), plasma malondialdehyde (MDA), superoxide dismutase (SOD), and H
S levels were measured. Human umbilical vein endothelial cells (HUVECs) were also used to elucidate the mechanism involved in the protect effect of H
S on the injured vessels.
Our results showed that GYY4137 normalized the SBP (P<0.0001), increased EDR (P<0.01), reduced oxidative stress (increased the content of SOD and reduced the content of MDA) of SHR. Meanwhile, GYY4137 could promote the proliferation (P<0.01) and migration (P<0.01) of HUVECs, increase the expression of endothelial NO synthase (eNOS) and Vascular Endothelial Growth Factor Receptor 2 (VEGFR2) both in SHR and HUVECs treated with GYY4137. In addition to the above results, the PIP3/Akt signaling pathway was activated and the expression of caspase 3 was increased by GYY4137. However, all the above effects of GYY4137 were blocked by ZD6474 (a VEGFR2 inhibitor).
GYY4137 had a hypotensive and vascular protect effect on PH. This effect might be mediated through upregulating the expression of VEGFR2, which subsequently alleviating oxidant-provoked vascular endothelial dysfunction, and promoting the proliferation and migration of endothelial cells in SHR.

Most hepatocellular carcinoma cases are diagnosed at late stages of the disease, which makes it the second cause of cancer mortality worldwide. For advanced-stage patients, chemotherapeutic drugs are the best treatment option; however, their adverse effects and high cost are still major obstacles for effective treatment. Spirulina microalga is a rich source of nutritional and bioactive elements and potential pharmaceuticals, which has an -proliferative effect against several cancer cell lines. It also has a prophylactic effect against the early stages of some cancer models, including hepatocellular carcinoma.
The present study was carried out to evaluate the therapeutic anticarcinogenic effect of spirulina against advanced murine hepatocellular carcinoma.
Hepatocarcinoma was induced by a single injection of diethylnitrosamine (100mg/kg, intraperitoneally) followed by 22 weekly injections of carbon-tetrachloride (0.5mg/kg, i.p). Spirulina (250 and 500mg/kg bw) was given orally, from week 25 to 28, after the establishment of hepatocellular carcinoma.
Spirulina inhibited HCC structural and functional alterations, manifested by improving the survival rate, significantly decreasing the tumor marker AFP, and the count and size of the hepatic nodules, as well as downstaging HCC. This was accompanied with the augmentation of the endogenous antioxidant capacity, apoptosis (Bax) and the tumor suppressor protein (p53), as well as the suppression of tissue levels of the lipid peroxidation marker (MDA) and neoangiogenesis marker (VEGF).
In conclusion, spirulina has an anticarcinogenic effect against advanced hepatocellular carcinoma exerted through activating the tumor suppressor protein p53 and apoptosis, and suppressing oxidative stress and angiogenesis.

Various evolutionary forces namely mutation pressure and natural selection influence the pattern of codon usage i.e. distinct for each gene/genome. We investigated the pattern of codon usage of eight human herpesvirus genomes and compared them with two other herpesvirus genomes namely murine herpesvirus 68 and bovine herpesvirus type 1.1 to elucidate its compositional features, pattern of codon usage across the genomes and report the differences of codon usage pattern of human herpesviruses from that of other two other viruses. link2 We also identified the similarity of the codon usage of human herpesviruses with its host (human). The genes were found to be CG rich in HHV2, HHV3, HHV4, HHV6, HHV7 and BH genomes while TA rich in HHV1, HHV5, HHV8 and MH genomes. The codon usage bias (CUB) of genes was low. A highly significant correlation was found among compositional contents depicting the role of mutational pressure along with natural selection in framing CUB. Several more frequently used codons as well as less frequently used codons were identified to be similar between each human virus and its host (human), while murine herpesvirus 68 and bovine herpesvirus type 1.1 genomes did not possess similar adaptation strategy as human herpesviruses to human (host), thus we could conclude that viral CUB might have been shaped as per their host's nature for better surveillance. Neutrality plot revealed mutational pressure mostly influenced the CUB of HHV1, HHV8 and MH viruses, while natural selection had a major impact in the CUB of HHV2, HHV3, HHV4, HHV5, HHV6, HHV7 and BH genomes.Foot-and-mouth disease (FMD) virus 3A protein regulates viral replication and virulence; thus, we generated BHK-Flp-In cell line expressing 3A protein because it can serve as helper cell line for infecting a replication defective FMDV to produce a live disabled vaccine. FMDV Asia1 3A was amplified, cloned in pcDNA vector and confirmed by sequencing. The 3A gene was subcloned in pcEF/FRT vector and transfected in BHK-Flp-In cells and transformed cells were selected by resistance to hygromycin and susceptibility to zeocin antibiotics. The BHK-Flp-In cells expressing 3A protein was designated as Flp-In3A. Western blot and immunofluorescence confirmed that Flp-In3A cells expressed FMDV3A protein. Absolute quantitation of 3A transcripts showed peak expression at 6 h in Flp-In3A cells followed by a sharp decrease and the cells showed growth retardation for 2 h post-seeding with cytoplasmic vacuolations with advancing time. Response to infection with FMDV Asia1 virus revealed smaller plaques in Flp-In3A cells. Then, we investigated the effect of FMDV3A expression on autophagy related genes by real time PCR. Most autophagy genes were upregulated by 9 h post-seeding of which, autophagosome marker LC3B-II was demonstrated by western blot. Transient expression of 3A in PK-15 cells upregulated both Th1 and Th2 genes. The study suggested that the expressed 3A protein of FMDV cannot be used for 3A trans-supplementation in helper cells; however, it acts as an endogenously processed antigen that has the potential to elicit immune response in vivo.The channel catfish virus (CCV) can cause lethal hemorrhagic infection in channel catfish, resulting in significant economic losses in the fish industry. Effective drugs for the virus are still lacking. Acyclovir is known as a potent antiviral agent against human herpes viruses and some animal DNA viruses. The present study was undertaken to explore the antiviral response and mechanism of acyclovir against CCV in channel catfish ovary (CCO) cells. Acyclovir was able to significantly inhibit the expression of viral genes related to CCV viral DNA synthesis and suppress viral replication at a safe concentration. link3 Furthermore, acyclovir blocked the cytopathic effects and apoptosis induced by CCV, thereby maintaining the normal cellular morphological structure, as shown by the protection of CCO cells from the formation of apoptotic bodies or nuclear fragmentation. Moreover, reverse transcript quantitative polymerase chain reaction (RT-qPCR) demonstrated that acyclovir suppressed the expression of caspase 3, caspase 8 and caspase 9, while there was no significant impact on the expression of the apoptosis-inhibiting gene bcl-2 in CCV-infected cells.
