Aims: To investigate whether hTERT mRNA expression could be used as a diagnostic and prognostic marker of bladder transitional cell carcinoma.
Methods: SYBR green I real-time fluorescence quantitative PCR method was used to quantify hTERT mRNA expression in exfoliated cells from patients with bladder transitional cell carcinomas.
Results: A significant correlation was observed between the level of hTERT mRNA expression in exfoliated cells collected in urine with pathological grade and clinical stage.
Conclusions: Our results show that SYBR green real-time fluorescence quantitative evaluation of hTERT mRNA could be a useful marker of tumor progression for the early diagnosis and prognosis of bladder cancers.

In homeostatic conditions, the basal progenitor cells of the esophagus differentiate into a stratified squamous epithelium. However, in the setting of acid exposure or inflammation, there is a marked failure of basal cell differentiation, leading to basal cell hyperplasia. We have previously shown that lysyl oxidase (LOX), a collagen crosslinking enzyme, is upregulated in the setting of allergic inflammation of the esophagus; however, its role beyond collagen crosslinking is unknown.

Self-amplifying RNA (saRNA) is an extremely promising platform because it can produce more protein for less RNA. We used a sort and sequence approach to identify host cell factors associated with transgene expression from saRNA; the hypothesis was that cells with different expression levels would have different transcriptomes. We tested this in CDK4/hTERT immortalized human muscle cells transfected with Venezuelan equine encephalitis virus (VEEV)-derived saRNA encoding GFP.

Aims: High telomerase activity has been detected in over 85 % of tumors, with the activation of hTERT being the most crucial mechanism for re-establishing telomerase activity. Activation of hTERT maintains telomere length in cells, enabling cancer cells to proliferate indefinitely. Nevertheless, the specific mechanism of telomerase activation in non-small cell lung cancer (NSCLC) remains unclear, and post-transcriptional regulation of hTERT could be a potential activation mechanism.

Fibroblasts are native residents in dermal layer of human skin which are important for dermal regeneration and essential during cutaneous wound healing by releasing inflammatory markers and actively migrate to close an open wound. Premature skin ageing due to methylglyoxal (MGO) has recently caught the attention considering its potential to accelerate the emergence of skin ageing signs, however previous studies were only focused in primary neonatal dermal fibroblast and NIH3t3 fibroblast cell line. Therefore, thorough investigation is required to study the impact of MGO on primary human dermal fibroblast isolated from adult subject (HDFa).

Telomerase presents over-expression in most cancer cells and has been used as a near-universal marker of cancer. Studies have revealed that inhibiting telomerase activity by utilizing oligonucleotides to down-regulate the expression of intracellular human telomerase reverse-transcriptase (hTERT) mRNA is an effective method of achieving anti-tumor therapy. Considering that oncogenic microRNA-21 has been proven to indirectly up-regulate hTERT expression and drive cancer metastasis and aggression through increased telomerase activity, here, we constructed an AS1411-functionallized oligonucleotide-conjugated gold nanoprobe (Au nanoprobe) to simultaneously down-regulate intracellular microRNA-21 and hTERT mRNA by using anti-sense oligonucleotide technology to explore their targeted anti-tumor therapy effect.
