Project Description

Please note that we are not a pharmacy or clinic, so we are unable to see patients and do not offer diagnostic and treatment services for individuals.

Alfa Cytology excels in developing sophisticated chemical and radioactive induction models specifically designed for thyroid cancer research. Our commitment lies in producing high-quality, reliable models that enable researchers globally to investigate the mechanisms of thyroid carcinogenesis and enhance the drug discovery process for effective treatments.

Introduction to Chemical/Radioactive Induction Models

Chemical and radioactive induction models are essential tools in thyroid cancer research. Chemical models utilize carcinogens like diethyl-nitrosamine (DEN) and methylnitrosourea (MNU) to induce cancer through DNA damage and hormonal disruption. Radioactive models use agents such as iodine-131 (¹³¹I) to simulate radiation exposure, leading to DNA damage and activating oncogenic pathways.

These models enable researchers to investigate the molecular mechanisms of thyroid cancer and evaluate new therapeutic strategies, bridging the gap between laboratory findings and clinical applications.

Characteristics of Thyroid Cancer Chemical/Radioactive Induction Models

Category	Chemical Induction Models	Radioactive Induction Models
Induction Methods	Use carcinogens to disrupt hormonal synthesis and induce DNA damage.	Use iodine-131 (¹³¹I) or external radiation to directly damage thyroid cell DNA, mimicking radiation exposure.
Carcinogenic Mechanisms	Oxidative stress and sustained TSH elevation promote cell proliferation and malignant transformation.	DNA double-strand breaks and gene rearrangements activate pathways like MAPK.
Animal Models	Genetically modified rats/mice to enhance susceptibility.	Similar (some models require genetic modifications, e.g., TPO-Cre transgenic mice).
Tumor Types	Mainly follicular thyroid carcinoma (FTC) or anaplastic thyroid cancer (ATC), often progressing from benign nodules.	Predominantly papillary thyroid carcinoma (PTC), with pathological features resembling human radiation-associated PTC.
Latency & Incidence	Long latency (months to >1 year), incidence depends on dosage and co-factors.	Short latency (months to 1 year), high incidence with single high-dose exposure.
Molecular Features	RAS mutations, PAX8/PPARγ rearrangements, significant epigenetic alterations.	RET/PTC rearrangements, BRAF mutations (similar to human radiation-associated thyroid cancer).
Applications	Study environmental carcinogens, drug screening, early lesion progression.	Investigate radiation carcinogenesis, targeted therapies, metastasis mechanisms.
Limitations	Requires prolonged dosing, low metastasis rates, often needs TSH stimulation.	Genetic background differences from spontaneous cancers; may require gene editing to enhance invasiveness.

Our Services

Precise Model Development

Chemical Induction Models: Utilize recognized carcinogens like diethyl-nitrosamine (DEN) and methylnitrosourea (MNU), along with low-iodine diets/TSH stimulation, to simulate follicular (FTC) and anaplastic thyroid cancers (ATC) featuring RAS mutations and PAX8/PPARγ rearrangements.
Radioactive Induction Models: Employ iodine-131 (¹³¹I) or X-rays to generate papillary thyroid cancer (PTC) driven by RET/PTC rearrangements and BRAF mutations, closely mimicking radiation-related cancers in humans.

Customized Model Design

Flexible Animal Strains: Choose from Fischer 344 rats, Balb/c mice, or genetically modified models like TPO-Cre for specific research needs, such as TP53 knockout for metastasis studies.
Optimized Induction Protocols: Tailor induction cycles (latency from months to a year) and dosage gradients to facilitate low/high invasiveness tumor modeling.
Combined Model Development: Implement both chemical and radioactive induction to replicate complex carcinogenic environments and investigate multi-factor interactions.

Preclinical Efficacy Evaluation Platform

Therapeutic Response Testing:
- Chemical models assess the efficacy of tyrosine kinase inhibitors and epigenetic drugs.
- Radioactive models evaluate the synergy of ¹³¹I with targeted therapies, providing data on tumor regression and survival.
Metastasis Intervention Studies: Establish lung metastasis models to validate the effects of anti-angiogenic or immunotherapy on distant lesions.
