The records are not clear, but Man has been sheltering the cat inside his home for over 12,000 years. The close proximity of this companion animal, however, goes beyond sharing the same roof; it extends to the great similarity found at the cellular and molecular levels. Researchers have found a striking resemblance between subtypes of feline mammary tumors and their human counterparts that goes...

Human ERBB2 is a proto-oncogene that codes for the erbB-2 epithelial growth factor receptor. In human breast cancer (HBC), erbB-2 protein overexpression has been repeatedly correlated with poor prognosis. In more recent works, underexpression of this gene has been described in HBC. Moreover, it is also recognised that oncogenes that are commonly amplified or deleted encompass point mutations, a...

Current research highlights the Hspb1 based screening of eight cat populations of the world to investigate the association of newly found locus within cat mammary tumors. Total 180 cats were screened on the basis of Hspb1 4 bp deletion locus (1514-1517del4) which was observed in six mammary tumor cases in Siamese cat breed. Case-control association study revealed the non-significance with P=0.2...

CASE SUMMARY A spayed 12-year-old female domestic shorthair cat presented with nodular lesions on the ventral-right thoracic wall after complete mastectomy 4 months previously. The prior diagnosis was tubulopapillary mammary carcinoma with axillary lymph node metastasis, and a recurrence was confirmed. A gradual and sequential increase in the total number of leukocytes with severe neutrophilia ...

Background: Molecular marker based cancer diagnosis gaining more attention in the current genomics era. So, Hspb1 and Tp53 gene characterization and their mRNA expression might be helpful in diagnosis andprognosis ofcat mammary adenocarcinoma. It will also add informationin comparative cancer genetics and genomics. Objectives: Eight tumors of Siamese cats were analyzed to ascertain germ-line an...

The human ERBB2 proto-oncogene is widely considered a key gene involved in human breast cancer onset and progression. Among spontaneous tumors, mammary tumors are the most frequent cause of cancer death in cats and second most frequent in humans. In fact, naturally occurring tumors in domestic animals, more particularly cat mammary tumors, have been proposed as a good model for human breast can...

Mammary cancer is the third most common cancer in the cat. The average age of cats presenting with mammary tumors is 10-12 years. Siamese cats appear to have twice the risk of developing mammary cancers than other breeds. Recent studies suggest that spayed female cats have a 40-60% lower risk of mammary cancer than intact females. There is a strong association with the use of synthetic progesti...

Vitásek R. , H. Dendisová: Treatment of Feline Mammary Fibroepithelial Hyperplasia Following a Single Injection of Proligestone. Acta Vet. Brno 2006, 75: 295-297. A case of fibroepithelial hyperplasia of the mammary gland in the cat is reported. A seven-monthold female cat was presented for diffuse enlargement of all of the mammary glands. The cat was treated with proligestone (Covinan®) for th...
