Known Propose Function

Long intergenic non-coding RNA has been selected for this specific assignment. LincRNA is defined as a type of non-coding RNA that have more than 200 nucleotides and do not overlap glossed coding genes.

Mechanism of Function

LincRNA plays a critical role in the regulation of biological processes [3]. In addition to that, it contributes about a half of human transcripts [3]

Experimental Evidence Support

The lincRNA falls in the category of noncoding RNAs. It also shows a vital part in cell differentiation, cell propagation, and remodeling of chromatin by the trans and cis mechanism through the use of proteins that are scaffolded [4]. Furthermore, it regulates the adjacent genes as well as taking part in the production of neuropeptides [4]. It is discovered that through the structural elements, lincRNA interacts with nucleic acids through sequence complimentary [4].

Altering LincRNA with Cancer Types

The Long intergenic non-coding RNA remodels architecture of the genome [4].It has also been altered in more than two cancer types whereby the nature of technology applied in the experiment was on public RNA sequence datasets of the four common solid cancers. [4]

Function

Most of the lincRNA have been identified of having no relationship with tumors. The realization was after investigating their functions by using a database. [4] LincRNA are identified with the capability of inhibiting the moment when they are undergoing sequestration. For example, the lincRNA has been identified to form a double-stranded structure that binds DNA. It is vital as it blocks receptors from target genes as well as their transcription through promoting stem cell multiplication as well as the formation of nuclear which in turn has affected expressions of genes. From annotated lincRNA, two polypeptides are obtained to regulate membrane pump that in turn controls relation of the muscle [4].

Polyadenylation

It is evident that lincRNA are involved in embryonic development. In addition to that lincRNA was identified to be having the lower expression by the approach of comparing them to PCGs. [4]

Nuclear

The research has shown that genomic mutations within cancer reside deep inside in the regions that do not convert proteins [6]. Those regions are usually transcribed into lincRNA [6]

Splicing Status and Isoforms

Notably, the action of splicing takes place through the concerted activities of multi-subunit complexes [2]. Cancer is also a type of disease that is characterized by a variety of epigenetics and genetic aberrations. [5]. It has been noted that the fundamental role of alternative splicing is to promote sustained proliferation signals in cancer. [2]

The defects in the alternative splicing are mostly found in the human tumors, and it results from mutations in splicing regulatory elements of particular kind of cancer [5]

Range of Expression

RNA splicing regulators have seen to emerge as a new class of oncoproteins as well as tumors suppressors [5]. It has also contributed to the progression of the disease through RNA isoforms modulation that is involved in seal cancer pathways [5].

Form of Expression

The Polyadenylation status illustrates that lincRNA have been identified to be vital controllers for transcription, epigenetic inflection as well as transformation. [3]

Other Functions of lincRNA

Some of the other functions of long intergenic non-coding RNA includes the development of stem cells as the key regulators in various cellular processes as well as binding and modulation of stability and translation of other RNAs [1].
