Abstract: Autosomal recessive congenital short bowel syndrome is caused by mutations in CLMP. No mutations were found in the affected males of a family with presumed X-linked congenital short bowel syndrome or in an isolated male patient. Our aim was to identify the disease-causing mutation in these patients. We performed mutation analysis of the second exon of FLNA in the two surviving affected males of the presumed X-linked family and in the isolated patient. We identified a novel 2-base-pair deletion in the second exon of FLNA in all these male patients. The deletion is located between two nearby methionines at the N-terminus of filamin A. Previous studies showed that translation of FLNA occurs from both methionines, resulting in two isoforms of the protein. We hypothesized that the longer isoform is no longer translated due to the mutation and that this mutation is therefore not lethal for males in utero. Our findings emphasize that congenital short bowel syndrome can be the presenting symptom in male patients with mutations in FLNA.

Abstract: AIM: This study aims to investigate the effect of ATP, EGF and combination of those two to the Natrium Iodide Symporter (NIS) expression in MCF7, SKBR3 and HaCaT cell lines. METHODS: MCF7, SKBR3 and HaCaT cell lines were treated with ATP, EGF and combination of those two for 6, 12 and 24 hours. The expression of NIS mRNA was measured through quantitative-reverse transcription-polymerase chain reaction (qRT-PCR). The NIS protein expression was confirmed by immunocytofluorescence. RESULTS: NIS mRNA was expressed in SKBR3 and HaCaT cell lines but not in MCF7. The levels of NIS mRNA expression, after treatment by epidermal growth factor (EGF), adenosine Tri-Phosphate (ATP) or the combination of both for 6 and 12 hours were not significantly different from those of untreated cells. However, the treatment by a combination of ATP and EGF for 24 hours increases the level of NIS mRNA expression by 1.6 fold higher than that of the untreated cells (1.6241 ± 0.3, p 0.05) and protein NIS expression increase significantly by the treatment than untreated cells (P 0.05). CONCLUSION: The level of NIS expression varies among the different subtypes of breast cancer cell lines. MCF7 cell line is representing the luminal A subtype of breast cancer does not express NIS. Only SKBR3 cell line express NIS and this subtype might be suitable to receive radioiodine therapy as those cells expressing NIS. A combination treatment of EGF and ATP increases the expression of NIS mRNA and protein at the membrane in SKBR3 cells.
