Introduction of 64-75-5 :

Tetracycline hydrochloride is a broad-spectrum antibiotic with oral activity. Tetracycline hydrochloride exhibits activity against a wide range of bacteria including gram-positive, gram-negative bacteria, chlamydiae, mycoplasmas and rickettsiae. Tetracycline hydrochloride can be used for the research of infections[1]. In Vitro:Tetracycline hydrochloride shows susceptibilfty of V. vulnlflcus strain B3547 with MIC value of 0.5 g/mL[2].
Tetracycline hydrochloride inhibits the L-amyloid aggregates formation and disassembles the pre-formed fibrils[3]. In Vivo:Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment
.

Tetracycline can be used in animal modeling to create genetically engineered disease models. The pharmacokinetics of Tetracycline after intraperitoneal administration in broiler chickens exhibit unique distribution and elimination characteristics. Tetracycline distributes widely in the body, with rapid elimination, high clearance, and a large volume of distribution. After oral administration, Tetracycline shows high gastrointestinal absorption and moderate elimination rates. Although the absorption rate of Tetracycline is higher than that of most other tetracycline drugs, its overall drug exposure is relatively low[4].

Induction of tumor regression based on BCR-ABL gene silencing[4]
Background
The BCR-ABL gene encodes an abnormal tyrosine kinase (BCR-ABL protein), which leads to uncontrolled cell proliferation. Tetracycline can induce tumor regression in mice by inhibiting BCR-ABL expression through the suppression of the binding between tTA (tetracycline transactivator) and the Tet-OP (Tetracycline Operator) sequence[4].
Specific Modeling Methods
Mice: nu/nu • female and male • 6-8 weeks old
Administration: 200 μg/ml • po • single dose
Note
1. Tetracycline is administered orally dissolved in drinking water containing 5% sucrose.
2. Mouse tumor model construction: To induce visible tumors, Ba/F3 cells transduced with SIN-p210 (a retrovirus carrying and inducing tetracycline-dependent BCR-ABL gene expression) are subcutaneously injected into nude mice.
Modeling Indicators
Phenotypic observation: The tumors established in the mice completely regress.
