"Regeneration Intelligence" For Diagnosis of Lung and Liver fibrosis and Glaucoma

Collaboration of Insilico Inc. with Atlas Regeneration Inc, Vision Genomic Inc and Howard University has given two high impact papers to explain use of newly developed Regeneration Intelligence tool for the identification of perturbation in pathways of lung and liver fibrosis and glaucoma. It can be used as diagnosis tool for the fibrosis that is often mis-diagnosed.

A) Lung and Liver Fibrosis

Fibrosis is a age related condition that is marked by the accumulation of extracellular matrix that occurs in wide range organs. This leads to changes in the structural and functional properties of organ that leads to pathological conditions. Lungs and liver are the most commonly affected by fibrotic situation leading to development of idiopathic pulmonary fibrosis (IPF) and hepatic fibrosis.

Figure 1 a - c
The figure 1 a) & b) shows venn diagram of common pathway up-regulated and down regulated respectively for lung and liver fibrosis c) venn diagram d) PAS values for 20 common signaling pathway of lung and liver fibrosis

By their new Regeneration Intelligence algorithm they were able to pin down to TFG-beta, IL6 and ILK signaling pathways, which were found to be conserved in fibro-genesis. The software provides a validated mathematical frame work for assessment of signaling pathway alteration that drives the fibrosis in organs like lungs and liver.

This work supports a theory that conserved signaling elements may shared by various fibrotic organs. It provides a new evidence that evolutionary conserved pathways can be used as therapeutic drug targets. The work was highlighted in Eureka Alert Science Magazine and Business Standard news letter. The scientific paper can be downloaded from this here.

B) Glaucoma 

Glaucoma is also kind of fibrotic condition. Primary open angle glaucoma (POAG) is most common form of glaucoma that is characterised by free aqueous humor (AH) outflow and logging between iris and cornea that do not get drained from trabecular meshwork (TM) due to clogging of the channels.  This causes damaging effect on the mesh like Lamina Cribrosa (LC) through which optic nerve bypass. They have used a software suite, AMD medicine to understand the molecular pathway that causes the accumulation of AH and prevention of its outflow by carrying out intracellular signalling pathway activation (SAP).                           Accepted paper can be found here

Figure 2:  It shows the pathology of formation of glaucoma due to increase intra ocular pressure due to blockage in the removal of AH. A) shows TM and optical nerve head containing TC. B) shows TM located between cornea and iris. It shows that AH produced by ciliary body is moved towards anterior end shown by arrows and expelled into schlemm's canal via TM.  C) shows flow of AH into schlemm's canal through juxtacanaliular tissue. AH outflow is blocked due to clogging in TM leads to increase in intra ocular pressure. D) Optic nerve head containing axon of RGC and lamina cribrosa structure. E) shows morphology of collagen fibres of lamina cribrosa. F) SEM trabecular meshwork and G) SEM of lamina cribrosa.

They have found that  TGF-beta causes activation of pro-fibrotic pathway in TM and LC. This activated pro-fibrotic pathway causes extracellular matrix re-modelling in TM and LC. This makes TM less efficient in draining the AH. This causes LC more susceptible to damage due to increase intra ocular pressure caused because of increased AH. They propose molecular pathways that could be used for developing therapeutic intervention against glaucoma. The significance of the finding was recently discussed Eureka Alert Science Magazine and Medical News. These two papers shows a proof principle that there are some common age related signalling pathways that are shared by organs. Regeneration Intelligence based mathematical frame work gives an opportunity to explore this tool towards study of common signatures for age related fibrosis in other organs of human body. This may give us an opportunity to design an effective therapeutic strategy to fight age related disease like fibrosis.

Companies Coming Together To Fight Ageing

Mergers Can Solve Ageing Problem!!

Merger of scientific brain may help to find out newer ways to fight ageing.

A. LifeExtension

Life extension is currently a 35 billion dollar supplement producing company. The company has nearly 20 years history of developing innovative products to fight ageing and age related diseases. History of the company in antiaging research:

* 1983: Their research showed that low doses of aspirin may help in reducing the incidence of heart attack. They also recommended the use of co enzyme Q10 (CoQ10) as an anti ageing nutrient.
* 1992: Introduction of melatonin in America for anti-ageing therapy
* 1996: Published research to check the level of fibrinogen as risk factor for cardiovascular disease
*1997: Introduced s-adenosyl methionine (SAM) for alleviating depression, arthritis and liver diseases.
*2000: They found that taking hight level of antioxidants for extended period of time helps in reducing the atherosclerosis
*2006: A relatively better form of CoQ10 that is absorbed relatively better than parent product.
*2010: They stressed that pomogranate, resveratrol and quercetin may help in fighting ageing.
*2012: Introduced a product featuring oleuropein that helps in modulation of arterial resistance and stiffness.
*2013: Introduction of supplements that consists of polyphenols gastrodin that works as brain shield against antioxidants, inflammatory and excitatory damage.
*2014: Introduction of formulation that supports adenosine monophosphate activated protein kinase (AMPK)
*2015: Introduction of pollen extract that promote prostate function and healthy urination.

B. Insilico Inc Collaboration With Life Extension

In silico Inc. has been a major point of attraction in my blogs about ageing. The company is being operated from John Hopkins University. They are a group of computational biogenrontologists who believe that they can cure ageing. The group is extensively working in the field of developing computational models for coming closer and closer to fight ageing.

Insilico Inc. joins hands with larger number of pharmaceutical company in the pursuit of slowing down the ageing process. Recently they have collaborated with Life Extension (a supplement producing company) with the aim of slowing that ageing process. With the long history of Life extension and progressive nature of Insilico Inc. there is a possibility of introduction of range of geroprotectors that may slow down the ageing process early next year (News Published: a) and b)

C. In Silico Inc. Collaboration With BioTime Inc.

BioTime Inc is a clinical stage regenerative medicine company that was focuses on the development of newer technologies fight ageing via. pluripotent cells. Unlike other pharmaceutical products that works on the basis of molecular drug targets, pathways and genetic expression profiles; BioTime's approach has been at the cellular level. Where the pluripotent cells can replace the damaged cells to provide therapeutic output. The simple it sounds the more complex it is. Regeneration of tissue from embryonic cells and formation of scar tissue for an adult for therapeutic purpose is extremely complex process. Hence, in June 2016 they collaborated with Insilico Inc. to study this complex process via machine learning method. The idea of this collaboration was combine the technological advances of AI by Insilico Inc. and pluripotent cells based therapy by BioTime to produce next generation therapeutic solutions for cancer and age related disease..

In this context, AI was developed by BioTime Inc called as Embryonic.AI. It is transcriptomic based classifier that can be used for searching the queries to check how much close is the sample to the embryonic state. Embryonic. AI is basically a deep learning machine that is validated based on the thousands of samples that representative of the human embryonic stem cells. This includes human embryonic stem cells (ESC), induced pluripotent stem cells (IPSC), embryonic progenitor cells (EPC), adult stem cells (ASC) and adult cells (AC). Once the query it provided to the AI it gives out score that acts as a measure of the development stage of cells. Where ES=1 represents embryonic state and ES=0 represents adult cellular states. Here is link to the FAQs that can be used for more details
