48. MicroRNA-421 Targets ROCK1 to Inhibit Papillary Thyroid Carcinoma ProgressionRui LiChangchun, China

MicroRNA-421 (miR-421) was reported to be involved in development and progression of multiple cancers. However, the functional roles and underlying regulatory mechanism of miR-421 in papillary thyroid carcinoma (PTC) are yet to be unraveled. Here, decreased miR-421 levels are reported in PTC tissues and cell lines when compared to adjacent normal tissues and control cells, respectively. Significantly, decreased miR-421 was closely associated with TNM stage and lymph node metastasis of PTC patients. Gain of functional assays pointed out that overexpression of miR-421 in PTC cells suppressed proliferation, migration and invasion, and promoted cell apoptosis. Moreover, rho-associated coiled-coil kinase 1 (ROCK1), a known oncogene, was identified as a direct target of miR-421 in PTC. Rho-associated coiled-coil kinase 1 expression was increased in PTC tissues, and its expression was negative correlated with miR-421 expression. Moreover, ROCK1 overexpression partially attenuated the inhibitory effect in PTC cells mediated by miR-421 overexpression. These results suggest that miR-421 inhibits PTC progression by functioning as a tumor suppressor through targeting ROCK1.

Most of FMTS probands diagnosed in North–West center of endocrinology and endocrine surgery of SPbSU clinic are adults 43.43 ± 14.53 y.o. So nearly all of their descendants are adolescents or adults too. For last 2 decades we have treated or observed 17 pediatric patients with FMTS. Twelve (70.6%) of them operated and 5—observed. They are 12.75 ± 3.70 and 6.20 ± 6.61 y.o., respectively. Mutations in 634 codon are most frequent among our cohort—9 (52.9%), 2 (11.8%) with 620 and 2 V804l. Rest had v804l, e768d, с 609. One refused evaluate RET status. Of those 5 all have normal serum calcitonin. Two of them (17, 8 y.o.) have v804l mutation with low penetration rate and normal serum calcitonin. Rest of observed 3 y.o. planed for surgery. Of all operated 10 (13.00 ± 3.68) had already medullary cancer with serum calcitonin of 107.38 ± 186.99 pg/mL. Nine had multifocal disease. Tumour was 7.40 ± 8.38 cm. Central compartment dissection was performed in 5 cases. Three had already lymphnode metastases. In 8 cases calcitonin dropped to zero. One had progressive disease with calcitonin doubling time 14 months. Last one had too short follow-up period. Temporary hypoparathyroidism rate was 50%. RLN injuries in 20% cases.
