Tetrandrine (TET), a traditional Chinese medicine, exerts remarkable anticancer activity on various cancer cells. However, little is known about the effect of TET on human prostate cancer cells, and the mechanism of function of TET on prostate cancer has not yet been elucidated. To investigate the effects of TET on the suppression of proliferation, induction of apoptosis, and inhibition of migr...

The tet(M) gene encodes a protein which is related to tetracycline ribosomal protection, one of the mechanisms of tetracycline resistance. A tet(M) gene that is 100% homologous to the tet(M) gene of Staphylococcus aureus has been found in a clinical isolate of Acinetobacter baumannii, which also carries the tet(A) gene encoding a tetracycline efflux pump.

The genetic basis for spontaneous resistance to tetracyline (Tet) and penicillin (Pen) in Neisseria gonorrhoeae was investigated. Tet and pen are polygenes which confer small but distinct levels of resistance to Tet and Pen, respectively. Mtr is a multiple-drug resistance polygene which increases resistance to Tet and Pen (as well as to other unrelated antibiotics). Tem is a modifier gene affec...

Doxycycline, a new generation tetracycline antibiotic, is currently one of choice for the treatment and prevention of infections caused by agents of biowarfare. We are developing real time PCR assays to detect tetracycline resistance genes in Gram-negative bacteria. The assay was developed as a multiplex SYBR Green I detection using the Roche Lightcycler and multi-melting peak analysis followed...

This study aimed to determine the protective effects of tetrandrine (Tet) on murine ischemia-injured retinal ganglion cells (RGCs). For this, we used serum deprivation cell model, glutamate and hydrogen peroxide (H2O2)-induced RGC-5 cell death models, and staurosporine-differentiated neuron-like RGC-5 in vitro. We also investigated cell survival of purified primary-cultured RGCs treated with Te...

The use of antibiotics in animal husbandry contributes to the worldwide problem of increasing antibiotic resistance in animal and human pathogens. Intensive animal production is considered an important source of antibiotic resistance genes released to the environment, while the contribution of smaller farms remains to be evaluated. Here we monitor the spread of tetracycline resistance (TC-r) ge...

Tetracycline is a broad-spectrum antibiotic used in humans, animals, and aquaculture; therefore, many bacteria from different ecosystems are exposed to this antibiotic. In order to determine the genetic basis for resistance to tetracycline in bacteria from the oral cavity, saliva and dental plaque samples were obtained from 20 healthy adults who had not taken antibiotics during the previous 3 m...

For estimating reliability Assam, colle...

Intrinsic resistances to tetracycline, vancomycin and erythromycin are common in Lactobacillus species; however, resistance to streptomycin, clindamycin, gentamicin, oxacillin and lincosamide is also reported in these species. Resistant markers tet(W), tet(M) and erm(B) have been frequently detected in the resistant strains while van(A), lnu(A) and tet(L) have also been found in some strains of...

OBJECTIVES The tet(W) gene provides tetracycline resistance to a wide range of anaerobic intestinal and ruminal bacteria, but little is known about the molecular organization of the tet(W) gene. The aim of this study was to gain new insights into the molecular organization of the tet(W) gene in bifidobacteria strains from humans. METHODS A segment of DNA encompassing the whole tet(W) gene and...
