Background: Cleft palate is one of the many congenital abnormalities that occur. Alpha-smooth muscle actin (ASMA) is the dominant actin of isoform in the smooth muscle cells and plays an important role in the process of fibrogenesis. Differentiation of fibroblasts into myofibroblasts is a key process in wound healing and tissue repair, but is harmful to tissue function when overuse such as hypertrophic scars. In wound healing Angiogenesis is essential for the supply of oxygen and nutrients to injured tissue cells and dividing tumor cells that have high metabolic requirements, angiogenesis stimulated by vascular endothelial growth factor (VEGF). ASMA and VEGF activity factors that influence the formation of post-action scarring which may cause impairment of maxillary development.

Objectives: Can be known for ASMA and VEGF expression in incomplete, unilateral and non-syndromic bilateral cleft palate patients.

Methods: In this study a laboratory deksripstif study of ASMA and VEGF expression was performed with ASMA and VEGF immunohistochemistry examination of mucosal tissue of incomplete, unilateral and bilateral cleft palate patients as well as clinical photo examination in the first, third and fourth week where tissue taking was performed at Celah Bibir dan Langit-Langit RSAB Harapan kita.

Results: Conducted tissue retrieval patients 4 patients cleft palate non-syndrome. One patient had a non syndromic bilateral cleft palate, one patient non syndromic incomplete cleft palate and two non syndromic unilateral cleft palate patients. Immunohistochemical examination results in non-syndromic bilateral cleft palate  higher than with unilateral and incomplete cleft palate patients. At the clinical photo examination, the wound healing in all four patients was achieved within four weeks.

Conclussion: There is a difference in ASMA and VEGF gene expression in the palatum mucosa in the case of incomplete, unilateral and bilateral non syndromic cleft patients affecting the rate of wound healing following primary palatoplasty surgery. Increased expression of asthma will cause an increase in the extent of fusion failure between the palatinus process. "

"Latar belakang: Palatoplasti merupakan tindakan operasi untuk merekonstruksi celah langit-langit, sehingga fungsi bicara maupun fungsi mastikasi dapat lebih baik. Pada proses penyembuhan pasca palatoplasti, akan terjadi gaya tarik dari flap mukoperiosteal yang disatukan. Gaya tarikan pada mukoperiosteal itu diduga dapat menyebabkan kontraksi jaringan dan menyebabkan terjadinya jaringan parut. Adanya pembentukan jaringan parut tersebut dapat menyebabkan gangguan pertumbuhan maksila baik ke arah antero-posterior maupun ke arah lateral. MMP-9 merupakan protein yang berperan penting dalam penyembuhan luka pada fase remodelling. Ekspresi MMP-9 ditemukan tinggi pada jaringan yang lebih sedikit terjadinya jaringan parut. Tujuan: Studi ini bertujuan untuk melihat ekspresi MMP-9 pada pasien pasca palatoplasti primer celah langit-langit unilateral komplit non sindromik. Metode: Studi dilakukan dengan pemeriksaan imunohistokimia pada sampel jaringan mukoperisoteal palatum pasien celah langit-langit pasca palatoplasti primer. Hasil: Pada pemeriksaan imunohistokimia didapatkan hasil intensitas ekspresi MMP-9 pada kelompok favorable berkisar 26,62 % hingga 41,30 %, sedangkan skor intensitas ekspresi MMP-9 kelompok unfavorable berkisar 8,78 % hingga 24,91 %. Kesimpulan: Intensitas ekspresi MMP-9 pada kelompok favorable lebih tinggi (rata-rata 41,30 %) daripada intensitas ekspresi MMP-9 kelompok unfavorable (rata-rata 16,50 %).

Background: Palatoplasty is an operation procedure to reconstruct a cleft palate, so that both speech and mastication functions can be better. In the post palatoplasty healing process, there will be a attraction of the mucoperiosteal flap unity. The attraction force on mucoperiosteal can make a tissue contraction and scarring. The formation of scar tissue can cause interference with the growth of the maxilla both antero-posterior and lateral. MMP-9 is a protein that plays an important role in wound healing at the remodeling phase. MMP-9 expression was high in tissue with less scarring. Objective: This study aims to observe the expression of MMP-9 in post primary palatoplasty non-syndromic complete unilateral cleft-palate patients. Methods: The study uses immunohistochemical examination of mucoperisoteal tissue samples of the palate of patients with cleft palate post primary palatoplasty. Results: In the immunohistochemical examination the results of MMP-9 expression intensity in the favorable group ranged from 26.62% to 41.30%, while the MMP-9 expression intensity score of the unfavorable group ranged from 8.78% to 24.91%. Conclusion: The intensity of MMP-9 expression in favorable groups was higher (on average 41.30%) than the intensity of MMP-9 expression in unfavorable groups (average of 16.50%)."

"Latar Belakang: ECP mampu menurunkan frekuensi angina, meningkatkan kualitas hidup, serta memperbaiki exercise–induced ischemia time. Manfaat tersebut dapat bertahan beberapa tahun setelah ECP. Mekanisme manfaat jangka panjang ECP tersebut telah dibuktikan akibat adanya angiogenesis yang diduga diperankan VEGF-A, VEGFR-2, dan miR-92a.Tujuan: Mengetahui efek ECP terhadap VEGF-A dan VEGFR-2, serta hubungannya dengan miR-92a pada pasien angina refrakter.Metode: Studi ini merupakan uji klinis acak tersamar ganda yang melibatkan 50 subjek dengan angina refrakter. Subjek dirandomisasi (1:1) ke dalam kelompok terapi ECP atau sham, yang masing-masing dilakukan selama 1 jam, hingga 35 kali. Kadar VEGF-A, VEGFR-2, dan miR-92a plasma diukur sebelum dan sesudah terapi menggunakan metode enzyme-linked immunosorbent assay (ELISA) untuk VEGF-A dan VEGFR-2, serta quantitative reverse transcription-polymerase chain reaction (qRT-PCR) untuk miR-92a. Keluaran klinis sekunder seperti derajat angina, kualitas hidup, 6-minutes walk test (6MWT), dan ejection fraction (EF) juga dinilai.Hasil: Kadar VEGF-A dan VEGFR-2 dipertahankan pada kelompok ECP, sedangkan kadar VEGF-A dan VEGFR-2 mengalami penurunan yang signifikan pada kelompok sham [ΔVEGF-A ECP vs sham: 1 (-139 to160) vs -136 (-237 to 67) pg/ml, p = 0.026; ΔVEGFR-2 ECP vs sham: -171(-844 to +1166) vs -517(-1549 to +1407) pg/ml, p = 0.021, respectively]. Kadar miR-92a meningkat secara signifikan pada kelompok ECP [5.1 (4.2 – 6.4) to 5.9 (4.8 – 6.4), p<0.001] and sham [5.2 (4.1 – 9.4) to 5.6 (4.8 – 6.3), p=0.008]. Tidak terdapat korelasi antara perubahan kadar VEGF-A, VEGFR-2, dan miR-92a [VEGF-A vs VEGFR-2 (r = 0.243, p = 0.09; uji Spearman), VEGF-A vs miR92-a (r = 0.229, p = 0.11; uji Spearman), dan VEGR-2 vs miR92-a (r = 0.08, p = 0.581; uji Spearman)].Kesimpulan: ECP mampu mempertahankan angiogenesis dengan cara mempertahankan kadar VEGF-A dan VEGFR-2. Pada kondisi iskemia, baik high shear stress (ECP) maupun low shear stress (sham) dapat menginduksi pelepasan miR-92a. ECP mempengaruhi VEGF-A, VEGFR-2, dan miR-92a secara independen.

Background: ECP is able to reduce angina frequency, improve quality of life, and improve exercise time-induced ischemia time. These benefits can last several years after the ECP. The mechanism for the long-term benefit of ECP has been proven by the presence of angiogenesis, which is thought to be mediated by VEGF-A, VEGFR-2, and miR-92a.

Objective: To determine the effect of ECP on VEGF-A and VEGFR-2, and its relationship with miR-92a in patients with refractory angina.

Methods: This study was a double-blind randomized clinical trial involving 50 subjects with refractory angina. Subjects were randomized (1:1) into either ECP or sham therapy groups, each administered for 1 hour, up to 35 times. Plasma VEGF-A, VEGFR-2, and miR-92a levels were measured before and after therapy using the enzyme-linked immunosorbent assay (ELISA) method for VEGF-A and VEGFR-2, as well as quantitative reverse transcription-polymerase chain reaction (qRT-PCR). ) for miR-92a. Secondary clinical outcomes such as degree of angina, quality of life, 6-minute walk test (6MWT), and ejection fraction (EF) were also assessed.

Results: VEGF-A and VEGFR-2 levels are maintained in the ECP group, while VEGF-A and VEGFR-2 levels decrease in the sham group [ΔVEGF-A ECP vs sham: 1 (-139 to160) vs -136 (-237 to 67) pg/ml, p = 0.026; VEGFR-2 ECP vs sham: -171(-844 to +1166) vs -517(-1549 to +1407) pg/ml, p = 0.021, respectively]. MiR-92a levels increase significantly in the ECP group [5.1 (4.2 – 6.4) to 5.9 (4.8 – 6.4), p<0.001] and sham [5.2 (4.1 – 9.4) to 5.6 (4.8 – 6.3), p=0.008]. There is no correlation between changes in VEGF-A, VEGFR-2, and miR-92a levels [VEGF-A vs VEGFR-2 (r = 0.243, p = 0.09; Spearman's test), VEGF-A vs miR92-a (r = 0.229 , p = 0.11; Spearman's test), and VEGR-2 vs. miR92-a (r = 0.08, p = 0.581; Spearman's test)].

Conclusion: ECP therapy is able to maintain angiogenesis by maintaining VEGF-A and VEGFR-2 levels. In ischemic conditions, both high shear stress (ECP) and low shear stress (sham) can induce the release of miR-92a. ECP affects VEGF-A, VEGFR-2, and miR-92a independently."

Colorectal cancer is the world’s second highest cause of cancer death. Current treatments for colorectal cancer lack in cost, toxicity, and effectivity. Lunasin has the effect of inhibiting cancer in vitro, hence lunasin might offer the solution of cost-effective therapy for colorectal cancer. We investigate the effect of lunasin-rich soybean extract (LSRE) on vascular endothelial growth factor (VEGF) expression which is responsible for angiogenesis in colorectal cancer. Thirty Swiss Webster mice were divided into six groups. All groups except the normal group were induced by azoxymethane (AOM) and dextran sodium sulfate (DSS). Negative control group received normal saline solution, whereas positive control group were treated with aspirin. LSRE were given to three experimental groups, each with different dosing (250 mg/KgBW, 300 mg/KgBW, and 350 mg/KgBW). On the fifth week, after the mice were terminated, the distal colon tissues were obtained and received immunohistochemistry staining, then observed under a microscope and analyzed using IHC profiler in ImageJ. Index acquired from IHC profiler were calculated to achieve H-score. VEGF expression was significantly decreased in 300 mg/KgBW (p=0.031) and 350 mg/KgBW (p=0.003) of EKKL by an average reduction of 33.202% and 43.334% respectively. However, there was no statistically significant difference between both groups."
