LSINCT5, a 2.6 Kb polyadenylated, long stress-induced non-coding transcript on the negative strand, which localized in the nucleus and potentially transcribed by RNA polymerase III, acts as a candidate biomarker in multiple cancers.

Annotated Information

Name

LSINCT5: long stress-induced non-coding transcript 5 (HGNC nomenclature)

Characteristics

LSINCT5 is a long ncRNA that is transcribed on the negative strand[1]

LSINCT5 is a 2.6 Kb polyadenylated, long stress-induced non-coding transcript that is on the negative strand, localized in the nucleus and potentially transcribed by RNA polymerase III.LSINCT5,The LSINCT5 transcript consists of a core sequence and two long interspersed elements (LINE 1M repeat and LINE 1ME repeat).[1].

LSINCT5 is located 829,825 bp downstream of the IRX4 gene and 31,529 bp upstream of the IRX2 gene, both genes closely related to tumor development. LSINCT5's disorder in gastrointestinal tumors may be the downstream effect of these two genes[2].

It belongs to the category of "Intergenic" in lncRNA classification.

Cellular Localization

Function

LSINCT5 knockdown causes a decrease in proliferation in MCF7 cancer cells [1].

LSINCT5 appears to play a role in cellular proliferation and also with the development of breast and ovarian cancers[1].

LSINCT5 may act as an oncogenic lncRNA by influencing many cellular processes, including proliferation, in the carcinogenesis of cancers such as breast cancer, ovarian cancer, and gastrointestinal cancer[2].

High expression levels of LSINCT5 were significantly associated with poor DFS (disease-free survival)and DSS (disease-specific )rates in both GC (gastric cancer)and CRC(colorectal cancer ) patients, which indicated that LSINCT5 is an independent prognostic indicator for the DFS and DSS rates of GC patients[2],

Diseases

  • breast cancer, ovarian cancer, gastric cancer, colorectal cancer

Expression

LSINCT5 is overexpressed in breast and ovarian cancer cell lines and tumor tissues, relative to their normal counterpart. In addition, knocking down the expression of LSINCT5 in cancer-derived cell lines causes a decrease in cellular proliferation[1].

The expression of LSINCT5 was significantly higher in GC and CRC tissues than in adjacent normal tissues. In addition, LSINCT5 expression was markedly increased in several gastrointestinal cancer cell lines compared with normal cell lines[2].

Note: For each edit version that is contributed by a specific person, his/her contribution is quantified as its edit quality multiplied by its edit quantity; the edit quantity amounts to the edit distance in comparsion with its previous version (that is, the minimum number of edit operations required to transform one string into the other), and the edit quality corresponds to whether the edit persists in comparison with the last version, ranging from -1, when the edit is entirely reverted (short-lived), to 1, indicating that the edit is totally preserved in the last version (long-lived). Please also note that contribution quantification may take time to reflect recent edits.
*Since one person may perform many discontinuous edits for a wiki page, contribution score is the sum of quantified contributions over all participated edits.
#Multiple successive edits provided by a researcher are counted as one edit.
ΛSummed edit quantity is the sum of edit quantities over all participated edits.
Averaged edit quality is the edit quality normalized over all participated edits.
