Cellular senescence is a permanent cell cycle arrest induced by damage or stress applied on proliferating cells. In a cell autonomous manner, senescence is a potent barrier to tumorgenesis and contributes to the cytotoxicity of some anti-cancer drugs. However, with age senescence cells accumulate and promote a number of pathological conditions. Therefore the elimination of senescent cells is desired in order to prevent tumor- and inflammation- related pathologies and also to inhibit tissue ageing.
Today, our understanding of the mechanisms regulating the viability of senescent cells is limited. It has been suggested that senescent cells are resistant to apoptosis. Therefore, senescent cells elimination may be achieved by modifying the resistance to apoptosis of these cells.
Here the researches demonstrate the first feasible therapeutic approach that leads to eradication of senescent cells. Combination of direct induction of apoptosis in senescent cells with induction of cell death by pro-inflammatory repose induce by p21 knockdown will lead to reduction of viable senescent cells.

Applications


  • A therapeutic impact on inflammatory and fibrotic disease
  • Therapy for age-related disease such as type 2 diabetes, Alzheimer’s disease, Atherosclerosis, cataracts, Chronic obstructive pulmonary disease (COPD), and Osteoporosis

Advantages


  • Effective elimination of senescent cells- removal of senescent cells can prevent or delay tissue dysfunction and extend health span
  • Does not damage normal cells even at high concentrations

Technology's Essence


Researches demonstrated that the anti-apoptotic proteins Bcl-xL and Bcl-w level were elevated in senescence cells of both human and mouse origin. A subsequent study, in which Bcl-xL and Bcl-w were knocked down by siRNA, revealed that a combined knock down of Bcl-xL and Bcl-w had synergic effect, resulting in reduction of 50% in cell viability. Thus the increased level of anti-apoptotic proteins Bcl-xL and Bcl-w may account for the apoptotic resistance of senescent cells. p21 knockdown induced pro-inflammatory response and cell death in senescent cells.
Overall, the researchers show that combined inhibition of the anti-apoptotic proteins Bcl-xL and Bcl-w allows specific elimination of senescent cells and might be used to treat diseases where senescent cells are present. The researchers also found that the same effect might be achieved by reducing the expression of p21 in senescent cells. Integrating both approaches propose a more effective therapy.

Despite progress in early detection and treatment, breast cancer remains a leading cause of cancer-related death in women. For example, in 2012 alone, 41,150 women in the United States died from breast cancer.

Targeted therapies, which are based on oncogenic genetic abnormalities, are commonly used to treat subgroups of breast cancer patients. Although these treatments show promising results, they are limited to only a subgroup of patients (for example, amplification of HER2 occurs in about 15% of breast cancers) and there is an unmet need for the identification of druggable targets with a major oncogenic role in breast cancer development.

The present invention relates to the identification of SYNJ2 as a novel target for breast cancer treatment. SYNJ2 expression is enhanced in a sub-population of breast cancer patients and its catalytic activity was shown to promoted cell migration and invasion. Furthermore, screening compound libraries identified SYNJ2-specific inhibitors that prevented cell migration, suggesting that SYNJ2 is a potential target for cancer treatment.

Applications


 


Advantages


  • Novel identification of SYNJ2 as a genetically aberrant and potentially druggable driver of tumor progression.
  • Specificity – the discovered SYNJ2 inhibitors do not inhibit SYNJ1 which plays additional roles in the nervous system.
  • Potential therapeutic effect – Inhibition of SYNJ2 in several cancer models blocks tumor progression and invasion.


Technology's Essence


SYNJ2 abundance is increased in breast tumors and it is correlated with poor prognosis and aggressive subtypes of breast cancer. Furthermore, growth factors involved in breast cancer metastasis can increase SYNJ2 expression in association with increased cell invasion.

SYNJ2 is localized to cellular protrusions involved in migration and matrix invasion and its phosphatase activity enhances tumor growth and metastasis in mice. Unlike wild-type SYNJ2, reexpression of a catalytic inactive mutant failed to restore invasiveness of cancer cells, indicating that the catalytic activity of SYNJ2 is essential for motility.

Using a high-throughput screening platform for the measurement of SYNJ2 activity, four specific SYNJ2 inhibitors were discovered. All of the four inhibitors were selective to SYNJ2 and didn’t have an effect on its brain-enriched kin, SYNJ1. In addition, all four compounds attenuated cellular invasion, suggesting that specific SYNJ2 inhibitors can be developed as potential drugs for cancer therapy.

MicroRNAs as potential biomarkers for ALS.
Amyotrophic Lateral Sclerosis (ALS) is a devastating disease that progressively destroys motor neurons in the brain and the spinal cord, eventually causing paralysis and death. Currently, there are approximately 25,000 patients with ALS in the USA, with a median age of onset of 55 years. Approximately 5–10% of patients with ALS have a family history, and these patients most frequently inherit the disease in an autosomal dominant manner. Family-based linkage studies have led to the identification of several genes for familial ALS. However these findings only explain a small fraction of all ALS cases. The majority of ALS cases have no obvious family history and are referred to as sporadic ALS. At present, there is no effective therapy for the disease and patients usually die within 2-5 years after the onset of symptoms. Thus, there is an urgent need for biomarkers that could substantially aid early diagnosis of ALS and will help in designing decisive clinical trials of new drugs. The present technology provides specific microRNAs that can serve as potential biomarkers for ALS.

Applications


  • Unique patterns of microRNA expression profile in the cerebrospinal fluid of ALS patients could be useful as molecular biomarkers for disease diagnosis and eventually prediction of therapeutic responses.
  • The suggested ALS biomarkers may be employed in drug development studies.

 


Advantages


  •  MicroRNAs can be precisely quantified using qRT-PCR that provides exceptionally high sensitivity and specificity of detection.
  • The small size of microRNAs offers a unique advantage since they are more stable and less prone to enzymatic degradation, and are therefore amenable to an accurate assessment of their expression levels.

Technology's Essence


MicroRNAs (miRNAs) are endogenous small noncoding RNAs that negatively regulate gene expression in a posttranscriptional fashion and contribute to a wide variety of biological processes. miRNAs play important roles in the development of the central nervous system and their involvement in neurodegenerative diseases such as Parkinson's disease and Alzheimer’s disease has been recently established. The outlined technology describes specific miRNAs that are enriched in motor neurons and are significantly downregulated in mouse models of hereditary motor neuron disease (SOD1G93A and SMN1). These miRNAs may serve as putative biomarkers for motor neuron diseases such as ALS by measurement of their expression levels in cerebrospinal fluid samples collected from affected individuals.
