Abstract

ABSTRACT BackgroundBreast cancer is the most common malignancy in women of which majority histological type is Invasive (Ductal) Carcinoma of No Special Type (NST). The prognosis in breast carcinoma is influenced by many factors such as age, tumor size, degree of histology, and lymph node metastasis. Another factor in the development and metastasis of breast cancer is the chemokine receptor CXCR4 and its ligand, CXCL12. Studies state that the expression of CXCR4 in Breast Invasive Carcinoma associated with clinicopathologic aspects remain unclear. This study aims to determine differences in the level of CXCR4 mRNA expression between clinicopathologic aspects in breast carcinoma..MethodA total of 50 samples of formalin-fixed paraffin-embedded (FFPE) tissues diagnosed as invasive breast carcinoma (NST) are used in this study. Samples are divided into groups, namely with and without lymph node metastasis, age <45 years and> 45 years, small and large size, low grade and high grade. CXCR4 mRNA expression is quantitatively examined by qRT-PCR. CXCR4 mRNA expression differences between various clinicopathologic aspects were analyzed by One-Way ANOVAResultOf the 50 samples, 26 samples (52%) revealed increased expression of CXCR4 mRNA compared to normal tissue. There were no significant differences in mRNA expression of  CXCR4 between various prognostic factors (p> 0.05) such as the status of lymph node metastasis, histologic grading, size, and age. However, the expression of CXCR4 mRNA is increased in breast carcinoma when compared to normal breast tissue. Nonetheless the level of CXCR4 expression alone is not associated to clinicopathologic aspects in invasive breast carcinoma.ConclusionCXCR4 mRNA expression did not differ significantly between the various clinicopathological aspects of invasive breast carcinoma. Keyword: invasive breast carcinoma, mRNA of CXCR4, Clinicopathologic aspects

Abstract

Pendahuluan: Data World Allergy Organization (WAO) tahun 2013 menunjukkan bahwa prevalensi alergi diperkirakan sekitar 30-40% dari populasi dunia. Reaksi alergi terjadi akibat pelepasan histamin oleh sel mast. Pengobatan alergi jangka panjang selama ini memiliki efek samping berupa ganggun kardiovaskuler, retensi urin, AGEP, dan gangguan saraf. Penelitian sebelumnya menunjukkan kuersetin mampu menghambat pelepasan histamin oleh sel mast. Pada analisis kimia, daun jambu biji mengandung kuersetin. Penelitian ini bertujuan untuk mengetahui efek antihistamin ekstrak daun jambu biji (Psidium guajava) pada tikus putih (Rattus norvegicus) yang diinduksi ovalbumin.Metode: Penelitian quasi experimental design dengan metode posttest only group design menggunakan 24 tikus yang dibagi kedalam 6 kelompok secara acak. Kelompok kontrol normal (KN) tanpa perlakuan, kontrol negatif (K-) yang hanya diinduksi ovalbumin, kontrol positif (K+) diberikan metilprednisolon, dan kelompok perlakuan (P1, P2, P3) diberikan ekstrak daun jambu biji dengan dosis, berikut 27 mg/200 gramBB, 54 mg/200 gramBB, dan 108 mg/200 gramBB. Pengamatan efek antihistamin berupa perhitungan rata-rata jumlah garuk tikus. Data dianalisis dengan menggunakan uji One-Way ANOVA dan dilanjutkan uji Post Hoc Tukey.Hasil: Hasil uji One-Way ANOVA menunjukkan perbedaan rata-rata jumlah garuk tikus antar kelompok perlakuan bermakna secara statistik (p=0,00). Berdasarkan hasil uji Tukey, kelompok K- (45,75±5,50) dibandingkan dengan kelompok KN (2,25±0,96) dan kelompok perlakuan ekstrak daun jambu biji berbagai dosis menunjukkan perbedaan rata-rata jumlah garuk tikus yang bermakna secara statistik (p=0,00). Hasil rata-rata jumlah garuk tikus pada kelompok KN (2,25±0,96) dibandingkan dengan P2 (9,00±0,82) tidak menunjukan  perbedaan yang bermakna secara statistik (p=0,085).Kesimpulan: Ekstrak daun jambu biji (Psidium guajava) memiliki efek antihistamin pada tikus putih (Rattus norvegicus) yang diinduksi ovalbumin.
