Peptide nucleic acids (PNAs) form stable and tight complexes with complementary DNA and/or RNA and would be promising antisense reagents if their cellular delivery could be improved. We show that a 21-mer PNA, complementary to the human galanin receptor type 1 mRNA, coupled to the cellular transporter peptides, transportan or pAntennapedia(43-58), is… (More)
Retinoblastoma (RB) is a children's ocular cancer caused by mutated retinoblastoma 1 (Rb1) gene on both alleles. Rb1 and other related genes could be regulated by microRNAs (miRNA) via complementarily pairing with their target sites. MicroRNA-21 (miR-21) possesses the oncogenic potential to target several tumor suppressor genes, including PDCD4, and… (More)
Triple-negative breast cancer (TNBC) represents 15 to 20% of all types of breast cancer; however, it accounts for a large number of metastatic cases and deaths, and there is still no effective treatment. The deregulation of microRNAs (miRNAs) in breast cancer has been widely reported. We previously identified that miR-638 was one of the most deregulated… (More)
Peptide nucleic acids (PNA) are nucleic acid analogues containing neutral amide backbone, forming stable and tight complexes with complementary DNA/RNA. However, it is unclear whether unmodified PNA can efficiently penetrate neuronal tissue in order to act as antisense reagent. Here we show that intrathecal (i.t.) injection of an unmodified antisense PNA… (More)
In this paper, a comprehensive production planning and scheduling model is developed for a typical semiconductor plant (fab). The proposed model includes two decision making policies on production planning and scheduling of the semiconductor manufacturing systems, release and dispatching policies. The proposed release and dispatching policies decides on… (More)
Thyroid carcinoma is an uncommon form of human cancer, with an outstanding overall cure rate. This excellent prognosis is based on the fact that well over 99% of thyroid cancers are primary tumors. Metastatic cancer to the thyroid remains very rare. We report a case of clear cell renal carcinoma metastatic to the thyroid gland 23 years after nephrectomy.
Carcinoma ex pleomorphic adenoma (CXPA) is a rare epithelial malignancy that arises from a primary or recurrent pleomorphic adenoma (PA). It may be noninvasive (NI) or invasive. NI CXPA is extremely rare. Preoperative diagnosis on fine needle aspiration (FNA) of CXPA may be difficult and poses a diagnostic challenge to clinicians and pathologists. Herein,… (More)
To determine the domains essential for G-protein coupling of the human galanin receptor type 1 (GalR1), we have used both GalR1 mutants and synthetic receptor-derived peptides in(125)I-galanin and [(35)S]-GTPgammaS binding studies. Replacement of potential phosphorylation sites by Leu in the third intracellular loop (IC3) of GalR1 did not affect K(D)values… (More)
