Background and Objectives : Serum stimulated thyroglobulin(stim Tg) was well-known for useful marker in detecting of recurrent or persistent papillary thyroid cancer after total thyroidectomy. Serum stim Tg level may be possibly related with recurrent tumor volume, but rarely studied. The purpose of this study was to examine the relationship between preoperative serum stim Tg level and recurrent tumor burden and to find additional clinical usefulness of stim Tg more than to detect a recurrence. Material and Methods : From January 2000 to December 2009, 40 patients who were operated due to neck recurrence of papillary thyroid cancer after total thyroidectomy were enrolled. All patients had preoperative stim Tg. We compared the clinical correlation of stim Tg and other variables to influence the preoperative stim Tg levels. Results : Preoperative stim Tg levels weren't correlated with site of recurrence, number of metastasis, maximal size, and presence of extra-capsular spread. But considerable increase of stim Tg more than 50ng/mL was identified in recurrence of lateral neck. Patients who have higher stim Tg level after surgery tend to be have higher preoperative stim Tg level. Conclusion : stim Tg was not elevated in 7.5% of recurrent PTC patients. Thus, other diagnostic modalities such as US may be important for these patients. If preoperative stim Tg was more than 50ng/mL, it may suggest recurrence in lateral neck and have less possibility to achieve postoperative biochemical remission.

In an attempt to evaluate the diagnostic singnificance of the serum thyroglobulin (TG) in various thyroid disease states, authors measured serum TG by radioimmunoassay technique in 20 cases of normal subject, 22 cases of hyperthyroidism, 12 cases of diffuse nontoxic goiter (DNG) and 96 cases of nodular nontoxic goiter(NNG). The results were as follows: 1. In 20 cases of normal subjects, serum TG level was $20.41{\pm}5.5ng/ml(M{\pm}S.D.)$. There was no significant difference between males ans females. 2. In 22 cases of hyperthyroidism, serum TG level was $60.23{\pm}34.56ng/ml$ and the range was from 22 to 175 ng/ml, which were significantly high levels comparing with normal controls (p<0.01). 3. In 12 cases of euthyroidism with DNG, serum TG was $37.28{\pm}27.36ng/ml$ and the range was from 14 to 89 ng/ml. In 96 cases of euthyroidism with NNG, serum TG was $70.43{\pm}78.18ng/ml$ and the range was from 12.8 to 440 ng/ml. Both groups showed significantly increased levels of TG than normal control (p<0.01). 4. 57 cases of NNG patients were analysed pathologically by operation or needle biopsy and the TG level of each disease group is as follows. Thyroid carcinoma (16 cases); $72.2{\pm}81.71ng/ml$, adenomatous goiter without cystic degeneration (15 cases); $74.86{\pm}45.64ng/ml(M{\pm}S.D.)$ and adenomatous goiter with cystic degeneration(23 cases); $73.56{\pm}64.78ng/ml(M{\pm}S.D.)$. There was no significant difference between each group. Also the TG levels of thyroiditis (5 cases) was $19.6{\pm}8.96ng/ml(M{\pm}S.D.)$. 5. There were no significant correlations between serum thyroid hormones and serum TG in each thyroid functional states.

분화된 갑상선암의 수술후 경과 관찰에서 암조직의 잔류, 전이, 혹은 재발로 생각하여 치료적 용량의 방사성 옥소를 투여한 30명의 환자를 대상으로 I-131 진단적 스캔과(5mCi 이하), Tc-99m MIBI 스캔, 갑상선호르몬 투여중의 티로글로블린(Tg(on)), 갑상선 호르몬 투여중단 후의 티로글로블린(Tg(off))및 I-131 치료적 용량 스캔을 시행하여 다음의 결과를 얻었다. 1) I-131 진단적 스캔의 양성율이 Tc-99m MIBI 스캔보다 13% 더 논게 나왔다. 2) Tg(on) 혹은 Tc-99m MIBI 스캔의 양성율에 비해 Tg(off) 혹은 I-131 진단적 스캔의 양성율이 Tg(off)의 양성 기준치와 상관없이 Tg(on)이 1.5ng/ml, 5ng/ml시 각각 14%, 18% 더 높았다. 3) Tg(on)의 예민도는 1.5ng/ml, 5ng/ml을 양성기준치로 할 경우 각각 68%, 50%로 나와 양성 기준치를 1.5ng/ml로 할 경우 더 높은 예민도를 보였으며 Tg(off)의 예민도는 양성 기준치를 10ng/m1, 40ng/ml로 할 경우 각각 77%, 59%를 보였다. 4) Tc-99m MIBI 스캔에 양성이면서 I-131 진단적 스캔에 위음성을 보였던 경우도 4예에 해당하였다. 결론적으로, Tc-99m MIBI 스캔은 갑상선 호르몬을 중단하지 않은채 Tg(on)과 함께 측정한다면 갑상선암의 재발을 스크리닝 하면서, Tg(off) 및 I-131 진단적 스캔을 보완할 수 있는 유용한 검사로 생각된다.

ERp29는 ER chaperone의 한 종류이지만 아직까지 세포내에서 그 기능은 명확하지 않다. 배양 갑상선세포 (FRTL-5)에서 ERp29의 발현은 TSH (thyroid stimulating hormone) 의존적으로 조절되며, ERp29가 과발현된 세포에서는 ERp29-ER chaperone가 긴밀한 관계를 유지하여 분비단백질인 Thyroglobulin의 분비량이 약 30% 증가되었다.

갑상선 호르몬은 2가지 형태, 즉 L-thyroxine(tetraiodothyronine, T4)과 L-triiodothyronine(T3)으로서 갑상선(thyroid gland)에서 합성된다. 요오드는 갑상선 호르몬의 핵심요소이며 음식물에 포함된 요오드는 섭취 후 소장에서 흡수되어 혈류를 통해 갑상선으로 운반되고, 갑상선에서 농축, 산화되어 thyroglobulin이라는 단백질의 구성 아미노산 중 tyrosine에 삽입됨으로써 T4와 T3를 생성하게 된다. 갑상선 호르몬의 합성에는 요오드 이외에도 셀레니움이 필수적이다. 요오드와 셀레니움은 미량원소로서 부족하면, 갑상선 호르몬 결핍 또는 갑상선 비대를 초래할 수 있다.

The role of PET in the diagnosis and management of thyroid cancer is discussed. The major role of F-18 FDG PET is on patients with discordant negative I-131 scan and a positive serum thyroglobulin values. F-18 FDG PET scan localized metastatic sites in I-131 scan-negative thyroid carcinoma patients with high accuracy. F-18 PET is also valuable in medullary thyroid cancer with high calcitonin level. Focal thyroid uptake in patients with non-thyroidal diseas has high likelihood of thyroid cancer.

Thyroid hormones play an important role in regulating metabolism and can affect homeostasis of fat depots. The gene encoding thyroglobulin (TG), producing the precursor for thyroid hormones, has been proposed as a positional and functional candidate gene for a QTL with an effect on fat deposition. The SNP occurs in the 5' promoter region of the TG gene and is widely used in marker assisted selection (MAS) programs to improve the predictability of marbling level and eating quality in beef cattle. In this study, we identified three SNPs at the 5' promoter region of the TG gene in Korean cattle. Of the three SNPs identified in TG gene, the C257T and A335G were previously unreported new SNPs. The sequence data were submitted to GenBank (GenBank accession number: AY615525). The previously reported C422T SNP showed three genotypes, CC, CT and TT, by digestion with the restriction enzyme MflI using the PCR-RFLP method. A new allelic variant corresponding to the C${\rightarrow}$T and A${\rightarrow}$G mutations at positions 257 and 335, respectively, could be detected by the SSCP analysis. The gene-specific SNP marker association analysis indicated that the C422T SNP marker was significantly associated (p<0.05) with marbling score. Animals with the CC and CT genotypes had higher marbling score than those with the TT genotype. Results from this study suggest that TG gene-specific SNP may be a useful marker for meat quality traits in future MAS programs in Korean cattle.
