Lack of Increased P15<sup>INK4B</sup> Protein Expression in Basal Cell Carcinomas
Moad, Ahmed Ismail Hassan,Tan, Mei Lan,Kaur, Gurjeet,Mabruk, Mohamed Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.12
Background: The basal cell carcinoma (BCC) is the most common non-melanoma skin cancer (NMSK). BCC might develop because of the faulty cell cycle arrest. $p15^{INK4b}$ is a tumor suppressor gene, involved in cell cycle arrest and inactivated in most human cancers. The role of $p15^{INK4b}$ protein expression in the genesis of BCC is as yet unknown. In a previous study we showed the absence of $p15^{INK4b}$ expression in the majority of tissue microarray cores of cutaneous squamous cell carcinoma (SCCs), another type of non-melanoma skin cancer, indicating that $p15^{INK4b}$ could possibly be involved in the pathogenesis of cutaneous SCC. The aim of this study was to investigate $p15^{INK4b}$ protein expression in BCCs. Materials and Method: Protein expression of $p15^{INK4b}$ in 35 cases of BCC tissue arrays and 19 cases of normal human skin tissue was studied using an immunohistochemical approach. Results: The expression of $p15^{INK4b}$ was not significantly different in the BCC cases as compared with normal human skin (p=0.356; p>0.05). In addition, there were no significant relationship between clinicopathologic variables of patients (age and sex) and $p15^{INK4b}$ protein expression. Conclusions: Our finding may indicate that $p15^{INK4b}$ protein expression does not play a role in the genesis of BCC.

Overexpression of EGFR Protein in Bruneian Lung Cancer Patients
Han, Yu Hao,Hamid, Mas R.W. Abdul,Telisinghe, Pemasiri Upali,Hussin, Juniadah Binti Haji,Mabruk, Mohamed Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.1
Background: Lung cancer is the leading cause of cancer death in Brunei Darussalam, accounting for almost 20% of the total. The epidermal growth factor receptor (EGFR) is a member of the erbB family of tyrosine kinase receptor proteins, which includes c-erbb2(HER2/neu), erb-B3, and erb-B4. EGFR overexpression is found in a third of all epithelial cancers, often associated with a poor prognosis. Materials and Methods: Protein expression of EGFR in 27 cases of lung cancer tissue samples and 9 cases of normal lung tissue samples was evaluated using an immunohistochemical approach. Results: The results demonstrated significant increase and overexpression of EGFR in Bruneian lung cancer tissue samples in comparison to normal lung tissue. However, there was no significant relationship between clinicopathologic variables (age and sex) of patients and EGFR protein expression. Conclusions: EGFR is overexpressed in Bruneian lung cancer patient tissue samples in comparison to normal lung tissue samples. This may indicate that EGFR protein over expression plays an important role in the genesis of this type of cancer in Brunei Darussalam.
