Endometriosis merupakan penyakit yang bersifat progresif, kronik, rekuren dan hingga saat ini etiologi pastinya belum diketahui. Gejala yang ditimbulkan endometriosis bervariasi mulai dari asimptomatik, nyeri pelvis hingga infertilitas. Beberapa studi terakhir di bidang biologi molekular menunjukkan adanya kemungkinan endometriosis sebagai penyakit epigenetik dan salah satu gen yang diketahui mengalami perubahan epigenetik adalah gen HOXA10. Gen HOXA10 berperan mengatur reseptivitas endometrium selama proses implantasi. Keberhasilan proses implantasi merupakan salah satu faktor yang berperan pada fertilitas wanita dan Gen HOXA10 memiliki peranan penting dalam proses implantasi tersebut. Metilasi gen HOXA10 mengalami peningkatan yang signifikan pada endometrium eutopik wanita yang mengalami endometriosis. Pada endometrium wanita yang mengalami endometriosis terdapat penurunan ekspresi HOXA10 yang signifikan dan hal tersebut mengindikasikan adanya gangguan pada reseptivitas uterus yang dapat berperan dalam menurunnya tingkat kesuburan.

Malignant peripheral nerve sheath tumor (MPNST) is a soft tissue sarcoma, which is difficult to distinguish from other spindle cell sarcomas. MPNST is hostile, with a high recurrence, and tends to metastasize hematogenously, especially to the lungs. A phase of the metastasis is a degradation of the extracellular matrix, where Matrix Metalloproteinase (MMP) plays an essential role in this process. Gelatinase-type MMP, MMP-2 and MMP-9, can degrade basal membrane and fibrillar collagen to open the invasion pathway. MMP-2 can degrade more collagen and non-collagen extracellular matrix than MMP-9. Therefore, the study aimed to see the relationship between MMP-2 overexpression and histopathological malignancy grading and other clinical prognostic variables. The study was conducted by immunohistochemical staining of MMP-2 in 39 cases, consisting of 19 cases of low-grade MPNST and 20 cases of high-grade MPNST. Subsequently, an analysis of the relationship between MMP-2 overexpression and the malignancy grading and clinical variables was performed, such as age, sex, and tumor size and location. MMP-2 overexpression was seen in 19 (95%) cases of high grade and three (15.8%) cases of low-grade MPNST (p 0.000). The study also found a significant relationship between MMP-2 overexpression and histopathology grading, which may be helpful to define the prognosis.

Background. 4-nitroquinoline 1-oxide (4NQO) is a water soluble carcinogen which is often used to induce cancer in oral cavity. Objective. The purpose of this study was to know the incidence of histopathological lesions in the tongue of rats after administration of 4-nitroquinoline 1-oxide (4NQO) for a model of oral carcinogenesis in the animal experimental laboratory. Materials and Methods. This study was conducted in the Department of Pathological Anatomy, Faculty of Medicine, University of Indonesia (FMUI). 4NQO (30 ppm) was administered by drinking water ad libitum to the Sprague Dawley (SD) rats during different time inductions (4-9 and 36-46 weeks). The present of tumor in oral cavity of the 4NQO-treated rats were observed macroscopically and microscopically. Tumor volume were measured based on the formula established by G. Carlsson. The degree of histological changes was determined according to observation towards their Hematoxylin and Eosin (HE) staining results. Results. Dysplasia and invasive squamous cell carcinoma (SCC) were respectively found in the tongue of the group given 4NQO for 4-9 and 36-46 weeks. The tongue from rats (4NQO for 36-46 weeks) exhibited whitish protuberant nodular lesions with the longest diameter was 17 mm. The histopathological lesion incidences for dysplasia and invasive SCC respectively were 25% (5/20) and 75% (15/20). The rats had tumor in their tongues with variation of degree alteration which proportional to the induction time. The extension of 4NQO induction time increasing the degree of change in the tumor. Conclusion. 4NQO represents a good model of carcinoma of tongue and gives consistence results with histological changes degree being related to duration of exposure.

Treatment for ovarian carcinoma is still far from optimal, animal models are still needed to study human epithelial ovarian cancer. Animal models of ovarian cancer are very important for understanding the pathogenesis of the disease and for testing new treatment strategies. Ovarian carcinogenesis models in mice have been modified and repaired to produce preneoplastic lesions and neoplastic ovaries that are pathogens resembling human ovarian cancer. Although spontaneous ovarian tumors in mice have been reported, some of the shortcomings of existing studies preclude their use as animal models of ovarian cancer. Because of this, many efforts have been made to develop animal models that are relevant for ovarian cancer. Experimental animal models are developed accurately to represent cellular and molecular changes associated with the initiation and development of human ovarian cancer. Accurate experimental models have significant potential in facilitating the development of better methods for early detection and treatment of ovarian cancer. Several animal models of ovarian cancer have been reported, including manipulation of various reproductive factors or exposure to carcinogens. The latest advance in ovarian cancer modeling is using genetically engineered mice.

Skin cancer is a disease that develops in the epidermis of the skin and can be invasive, such as squamous cell carcinoma (SCC). Early detection of squamous cell precancerous can prevent these lesions from progressing to invasive SCC and increase the effectiveness of therapy. 5-fluorouracil (5-FU) is an antimetabolite compound as a pyrimidine DNA/RNA antagonist molecule that induces cell apoptosis. The main objective of this study was to evaluate the effectiveness of the topical 5-FU cream (Dharmais NCH) compared to imiquimod 5% on apoptosis through the expression of caspase-3 in precancerous squamous cells of mouse skin induced by 7,12-dimethylbenzen[a]-anthracene (DMBA)/croton oil treatment. This research assess three differences concentration of 5-FU include 1%, 2%, and 5% on 24 wild type mouse divided into 6 groups including positive control (with carcinogenesis but without treatment), negative control (without treatment; normal), carcinogenesis with treatment 5-FU cream (1%, 2%, and 5%) or 5% imiquimod cream. Two-stages carcinogenesis induced by DMBA and followed by croton oil. The expression of caspase-3 was analyzed using immunohistochemistry. Statistical analysis was performed by one-way ANOVA using SPSS version 23. The induction of two-stages of carcinogenesis (weeks 1 to 10) caused papilloma lesions on the skin of mouse. Furthermore, 5-FU treatment for 4 weeks (weeks 11 to 14) showed a decrease in the cumulative number of papillomas (p<0.05) and immunohistochemical analysis showed caspase-3 expression on 5-FU treatments (1%, 2%, and 5%) was not significantly different from the imiquimod treatment (p>0.05). The apoptotic effect of 5-FU treatment on precancerous skin squamous cell lesions in mouse was not significantly different from the standard treatment using imiquimod. This suggests that 5-FU treatment has potential as a future therapy in squamous cell precancerous skin lesions.Keywords: 5-fluorouracil, caspase-3, squamous cell precancerous, skin, topical treatment.

Abstrackhuman breast cancer incidence varied around the world, where the incidence in Asia is lower than western. Different types if mice in both parts of the world suggestive associated with the incidence of human breast cancer, in which M.domesticus the main carrier of virus more widely available in western. Mouse Mammary Tumor Virus (MMTV) is a type B retrovirus that causes breast cancer in mice. MMTV has a genome consisting of longterminal Repeat (LTR), Pol, Gag, Pro, and Env. MMTV has the ability to tumorigenesis by insertion mutagenesis and may affect genes that are close to the insertion. Transmission of this virus occurs through two channels, namely endogenous and exogenous. Endogenous pathways through the germline, while the exogenous pathway the milk. Several studies have shown the existence of sequence similarity in Env and MMTV LTR by human breast cancer, so that suspected a link between MMTV in human breast cancer. The presence of MMTV in the rate of progression of disease was also found in line, where the higher the degree of malignancy of a tumor also increased the number of MMTV sequences. However, until now we do not know how the MMTV can infect humans, so its role as a cause of human breast cancer is uncertain.Key words : MMTV, breast cancer
