Question: Change in gene expression associated with pancreatic cancer could be attributed to the variation in histone posttranslational modifications leading to subsequent remodeling of the chromatin template during transcription. However, the interconnected network of molecules involved in regulating such processes remains elusive. hPaf1/PD2, a subunit of the human PAF-complex, involved in the regulation of transcriptional elongation has oncogenic potential. Our study explores the possibility that regulation of histone methylation by hPaf1 can contribute towards alteration in gene expression by nucleosomal rearrangement. Here, we show that knockdown of hPaf1/PD2 leads to decreased di- and tri-methylation at histone H3 lysine 4 residues in pancreatic cancer cells. Interestingly, hPaf1/PD2 colocalizes with MLL1 (Mixed Lineage Leukemia 1), a histone methyltransferase that methylates H3K4 residues. Also, a reduction in hPaf1 level resulted in reduced MLL1 expression and a corresponding decrease in the level of CHD1 (Chromohelicase DNA-binding protein 1), an ATPase dependent chromatin remodeling enzyme that specifically binds to H3K4 di and trimethyl marks. hPaf1/PD2 was also found to interact and colocalize with CHD1 in both cytoplasmic and nuclear extracts of pancreatic cancer cells. Further, reduced level of CHD1 localization in the nucleus in hPaf1/PD2 Knockdown cells could be rescued by ectopic expression of hPaf1/PD2. Micrococcal nuclease digestion showed an altered chromatin structure in hPaf1/PD2-KD cells. Overall, our results suggest that hPaf1/PD2 in association with MLL1 regulates methylation of H3K4 residues, as well as interacts and regulates nuclear shuttling of chromatin remodeling protein CHD1, facilitating its function in pancreatic cancer cells.

Answer: Which is the histone residue methylated by MLL1?

Question: To demonstrate the importance of preventive measures when a case of tuberculosis is detected, identify the causes that favored a tuberculosis outbreak in a school and determine the efficiency of obtaining induced sputum samples. Descriptive, study. The Santa Maria de la Providencia school, located in the municipality of Alcala de Henares in Spain. On April 11, 2005, a case of bacilliform pulmonary tuberculosis was notified in a teacher. Study of contacts in the collective was performed as a programmed intervention. Mantoux skin test and, if positive, chest radiograph were performed in contacts. Treatment of latent or active tuberculosis was recommended according to the result. School exposures were identified and underwent the Mantoux skin test (142 students in years 1, 2, 3, and 4 of compulsory secondary education and 22 teachers). The Mantoux test was positive in 68 students (48 %) and seven teachers (32 %). In seven students with results compatible with active tuberculosis disease, sputum induction was performed and treatment was started. A further two students, identified as contacts, were studied in another center and also started treatment for active tuberculosis disease. Due to the high risk of contagion, study of contacts was extended to the remaining students in compulsory secondary education. In this second phase, 134 students received the Mantoux skin test and seven were Mantoux positive (5.2 %). In all these students, active tuberculosis disease was ruled out. Latent tuberculosis treatment was recommended in all Mantoux-positive contacts.

Answer:
The Mantoux test detects what latent infection/disease?
