Relationship between promoter methylation and protein expression of glutathione S-transferase gene class P1 in breast cancer

Glutathione S-transferase gene class P1 (GSTP1) encodes glutathione S-transferase P1 (GSTP1) that catalyses detoxifying metabolism of glutathione. The lack of GSTP1 expression is linked to carcinogen-esis and is related to promoter methylation. The previous studies of GSTP1 hypermethylation in breast cancer reveal diverse results and suspicious...Continue reading →

Primary central nervous system lymphoma presenting with panhypopituitarism and diabetes insipidus

Lymphoma involving the hypothalamus is very rare. We present a case of a 48-year-old man with primary central nervous system lymphoma (PCNSL) presenting with hypothalamic and pituitary stalk lesions with frontal masses, causing diabetes insipidus and panhypopituitarism. Brain MRI with gadolinium enhancement demonstrated vivid enhancing hypothalamic and...Continue reading →

The role of Immunohistochemistry in diagnosis of renal cell carcinoma subtypes.

To determine the validity of immunohistochemistry in classifying Renal cell carcinoma (RCC) subtypes. Methods: Eighty-three cases of RCC were retrieved. Immunohistochemical staining of Vimentin, CD10, CK7, P504s, Parvalbumin, TFE3, and CD117 were done by using tissue microarray blocks. RCC subtypes were placed and compared with the previous diagnosis....Continue reading →

Impact of CpG site specific methylation on silencing protein expression of GSTP1 in breast cancer

From previous study with Methylation specific polymerase chain reaction (MSP), there were cases of DNA methylation showing positive protein expression. Some CpG sites of the primer were speculated to have no effect on protein expression....Continue reading →

Determination of Asbestos Bodies in Autopsy Lung Fluid

The finding of asbestos bodies in lung fluid aspirates represents definite evidence of having prior exposure to asbestos, and having asbestos fibers entering the bronchial tree. After entering the lung, fibers undergo a coating process with ferritin protein to form asbestos bodies. The present study was carried out with the aim of determining...Continue reading →

Comparison of α-smooth muscle actin expression between squamous cell carcinoma and pseudoepitheliomatous hyperplasia

To evaluate the usefulness of α-smooth muscle actin (α-SMA) expression of reactive myofibroblastic cells within desmoplastic reaction tissue for distinction between invasive squamous cell carcinoma (SCC) and pseudoepitheliomatous hyperplasia (PEH)....Continue reading →

Gap Analysis Study before Implementation of Thailand’s National Guidelines for Point of Care Testing at Chiang Rai Province

The Bureau of Laboratory Quality Standards has published Thailand’s National Guidelines for Point-of-Care Testing (POCT) since August 2015. Still yet, the implementation of the guidelines is a great challenge....Continue reading →
