Breast cancer is the most common malignancy in women worldwide. The incidence of breast
cancer in Malaysia is lower compared to international statistics, with peak occurrence in the age
group between 50 to 59 years of age and mortality rates of 18.6%. Despite current diagnostic and
prognostic methods, the outcome for individual subjects remain poor. This is in part due to breast
cancers’ wide genetic heterogeneity. Various platforms for genetics studies are now employed
to determine the identity of these genetic abnormalities, including microarray methods like highdensity
single-nucleotide-polymorphism (SNP) oligonucleotide arrays which combine the power of
chromosomal comparative genomic hybridization (cCGH) and loss of heterozygosity (LOH) in the
offering of higher-resolution mappings. These platforms and their applications in highlighting the
genomic alteration frameworks manifested in breast carcinoma will be discussed.
2.Clinical manifestation and sensitization of allergic children from Malaysia
Asia Pacific Allergy 2015;5(2):78-83
BACKGROUND: An epidemiological rise of allergic diseases in developing countries raises new challenges. Currently a paucity of data exists describing allergy symptomology and sensitization to common food and aeroallergens in young children from developing countries. OBJECTIVE: To compare changes in symptomology, food allergen sensitization and aeroallergen sensitization in a cross-sectional study of children < 2 years and 2-10 years. METHODS: A total of 192 allergic children (aged < 2 years, 35 children; aged 2-10 years, 157 children) underwent specific IgE (>0.35 kU/L) to common food (egg white, cow's milk, cod fish, wheat, peanut, soya, peanut, and shrimp) and house dust mites (Dermatophagoides pteronyssinus and Blomia tropicalis). RESULTS: In children < 2 years, atopic dermatitis (65.7%) was the most common symptom whereas in children 2-10 years it was rhinoconjunctivitis (74.5%). Higher sensitization rate to eggs (p < 0.01) and cow's milk (p = 0.044) was seen in < 2 years group when compared to the 2-10 years group, but no significant differences for shrimp (p = 0.29), wheat (p = 0.23) and soya (p = 0.057). Interestingly, sensitization to peanut (p = 0.012) and fish (p = 0.035) was significantly decreased in the 2-10 years group. Sensitization to house dust mites (p < 0.01) dramatically increased in the older children. CONCLUSION: Our study supports concept of atopic march from a developing country like Malaysia.

Objective: To identify commonly regulated genes in HPV-infected HeLa and CaSki cervical cancer cells treated with curcumin analogue 1,5-bis(2-hydroxyphenyl)-1,4-pentadiene-3-one (MS17) and to explore potential mechanisms that underlie its cytotoxic, anti-proliferative and apoptotic activity. Methods: HeLa and CaSki cells were treated with 2 × EC

Objective: To identify mutually regulated proteins in PC-3 and DU145 androgen-independent prostate cancer cell lines treated with 1,5-bis(2-hydroxyphenyl)-1,4-pentadiene-3-one (MS17), and to study the molecular pathways that contributed to the anticancer activity of MS17. Methods: PC-3 and DU145 cells were treated with 3 × EC
