Environmental Microbiology, as a compulsory foundational course for the major of environmental and ecological engineering. Its knowledge system not only lays a profound theoretical foundation but also evinces a close-knit nexus to practical applications in environmental protection and ecological restoration. This course thus serves as an outstanding platform facilitating both teaching reforms and practical innovations of professional courses. With Environmental Microbiology as a paradigmatic illustration, this paper concentrates on addressing issues like archaic course contents and enervating teaching approaches, with the aspiration of augmenting students' professional acuities, practical dexterities, and innovation and entrepreneurial aptitudes. In light of the aforesaid aim, we initiated an all-encompassing probe into the teaching reform and practicable paradigms from the perspective of amalgamating professional education with innovation-steered stratagems. Across multiple fronts, comprehensive reformative undertakings were implemented, subsuming the optimization and reconfiguration of course contents, the exploration of sundry teaching methodologies, and the scientific erection of an evaluation system. Ultimately, a nascent teaching model dubbed "three-dimensional, six-loop and five-collaborative" was formed. This series of comprehensive and innovative reform measures has not only substantially augmented the profundity and extensiveness of professional knowledge, permeating into the core of disciplinary essence, but also remarkably bolstered students' practical operational capabilities and innovative thinking patterns, thereby catalyzing their transformation into well-rounded individuals with a competitive edge. By virtue of these efforts, a solid foundation has been firmly laid for the teaching reform of Environmental Microbiology and the cultivation of high-caliber environmental professionals in the contemporary era, heralding a new chapter in the development of environmental education.

Objective To investigate the effect of Keap1?Nrf2 pathway on cell proliferation, metastasis and drug resistance of human lung cancer A549 cell line. Methods A549?Keap1 cell line, constantly expressing wild type Keap1, was established by lentiviral transfection. Real?time RT?PCR and western blot were used to determine the expression of Nrf2 and its target gene in A549 cells. Sulforhodamine B ( SRB) assay, flow cytometry, colony formation assay, transwell assay, and cell wound?healing assay were performed to explore the effect of wild type Keap1 expression on the proliferation, invasion, migration and drug resistance of A549 cells. Results Over?expressed Keap1 decreased the expression of Nrf2 protein and
the mRNA level of its downstream target genes and inhibited the ability of cell proliferation and clone formation of A549 cells. Keap1 overexpression induced G0/G1 phase arrest. The percentage of A549?Keap1 cells in G0/G1 phase was significantly higher than that of A549?GFP cells (80.2±5.9)% vs. (67.1±0.9%) (P<0.05). Compared with the invasive A549?Keap1 cells (156.33±17.37), the number of invasive A549?GFP cells was significantly higher (306.67±22.19) in a high power field. Keap1 overexpression significantly enhanced the sensitivity of A549 cells to carboplatin and gemcitabine ( P<0.01) . The IC50s of carboplatin in A549?Keap1 and A549?GFP cells were (52.1±3.3) μmol/L and (107.8±12.9) μmol/L, respectively. The IC50s of gemcitabine in A549?Keap1 and A549?GFP cells were (6.8±1.2) μmol/L and (9.9±0.5) μmol/L, respectively. Conclusion Keap1 overexpression significantly inhibits the expression of Nrf2 and its downstream target genes, suppresses tumor cell proliferation and metastasis, and enhances the sensitivity of A549 cells to anticancer drugs.

OBJECTIVETo investigate the differential gene expression profile from patients with Bardet-Biedl syndrome (BBS) by oligonucleotide microarray technique.

METHODSTotal RNA of 3 probands with BBS and 4 healthy siblings were isolated from peripheral blood mononuclear cells and reverse-transcribed to cDNAs. Then the cDNAs were subjected for microarray screening with Affymetrix U133 Plus 2.0 array. Genechip scanner was applied to screen the hybridization signals. Genes differentially expressed between the BBS probands and controls were identified by using GCOS1.4 software with the standard of two-fold change (P<0.05) of expression.

RESULTSFifteen genes were up-regulated 2 or more fold and another 15 genes were down-regulated 2 or more fold in the BBS patients, among them 12 genes were related to signaling pathway and cell cycle by Gene Ontology (GO) analysis.

CONCLUSIONThe differentially expressed genes identified may correlate with the function or structure of cilia. Their roles in the BBS genesis need to be further studied.
