14 / Silencing this gene
From Hif1a to a sequence that silences it
The AUMsilence™ platform designs the sequences against the mouse transcripts on this page. Six decisions are yours before it does. What is written under each is AUM's guidance; the timings and the concentrations are in the usage guide below.
01
Choose the region
A knockdown oligonucleotide can sit in the 5' untranslated region, the coding sequence or the 3' untranslated region, and all three are used. The coding sequence and the 3' untranslated region are the usual first choices for an RNase H design; the 5' end near the start codon suits a steric block. The map above shows where each region sits on the isoforms it draws.
02
Cover the isoforms you mean
An exon every isoform carries silences the whole gene; an exon only some isoforms carry silences those and spares the rest. Decide which you want before a sequence is chosen, and check the reference transcript (MANE Select in human; RefSeq Select and Ensembl canonical in mouse and rat) is the one your cells express.
03
Think across species early
The orthologs panel says whether mouse and rat carry the same gene. Whether one oligonucleotide can serve two species is a sequence question, settled at design by matching the candidate against each transcript, not by the protein identity shown there.
04
Check expression in your model
A transcript that is not expressed in your cells cannot show knockdown. Confirm the gene is expressed in the cell type and condition you will use, from your own data or a reference atlas, before the order. The expression panel above gives GTEx's median per tissue for a human gene; for mouse and rat it says that no atlas is on this page yet.
05
Run the controls
A scramble control of the same chemistry, a positive control against a gene known to knock down in your cells, untreated cells, and a mock condition where a transfection reagent is used. Read knockdown at the RNA level first, then at the protein; the usage guide gives the timing and the concentrations to start from.
06
Pick the product
AUMsilence sdASO needs no transfection reagent and works in the cells that resist one. AUMsilence toASO is the transfection-optimised version of the same design, and AUMsiRNA™ is the siRNA route. The selection guide compares them.

Gene summary
This gene encodes the alpha subunit which, along with the beta subunit, forms a heterodimeric transcription factor that regulates the cellular and developmental response to reduced oxygen tension. The transcription factor has been shown to regulate genes involved in several biological processes, including erythropoiesis and angiogenesis which aid in increased delivery of oxygen to hypoxic regions. The transcription factor also plays a role in the induction of genes involved in cell proliferation and survival, energy metabolism, apoptosis, and glucose and iron metabolism. Alternative splicing results in multiple transcript variants encoding different isoforms.

Functions as a master transcriptional regulator of the adaptive response to hypoxia (PubMed:15225651, PubMed:17981124, PubMed:22009797). Under hypoxic conditions, activates the transcription of over 40 genes, including erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, HILPDA, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia (PubMed:15225651, PubMed:17981124, PubMed:22009797, PubMed:22100406, PubMed:37558878). Plays an essential role in embryonic vascularization, tumor angiogenesis and pathophysiology of ischemic disease (PubMed:22009797). Heterodimerizes with ARNT; heterodimer binds to core DNA sequence 5'-TACGTG-3' within the hypoxia response element (HRE) of target gene promoters (PubMed:26245371). Activation requires recruitment of transcriptional coactivators such as CREBBP and EP300. Activity is enhanced by interaction with NCOA1 and/or NCOA2. Interaction with redox regulatory protein APEX1 seems to activate CTAD and potentiates activation by NCOA1 and CREBBP. Involved in the axonal distribution and transport of mitochondria in neurons during hypoxia (By similarity)

NM_010431.3NM_010431.3RefSeq Select
Drawn 5' to 3' from each transcript's exons as placed on the reference assembly; exon 1 is the 5' exon on the transcript's own strand. Exon blocks are to scale with each other; introns are drawn at one fixed width whatever their length, so the map is not to scale along the chromosome. Numbers are exon ranks along the strand; a rank is omitted where the exon is too narrow to carry it.
A window on one transcript
One pixel of the map above stands for several bases, and a block too short to see is drawn wider than its own scale, so the map chooses a region and the sequence here chooses the window. Click an exon on a row of the map, or drag across a row; then set the exact start and end below.
These controls are ready in a moment.
No transcript is chosen.
Once a window is chosen this panel shows its length, its G and C count as a percentage of that length, the letters it is made of, the exons it falls in, whether it crosses a junction, and its antisense strand.
