Beschreibung (Description)

SAICAR is an intermediate metabolite in the de novo synthesis pathway of purine nucleotides. SAICAR can selectively activate the pyruvate kinase M2 isoform (PKM2; EC50=0.3mM) in an isoform-specific manner[1-2]. The accumulation of SAICAR induces nuclear translocation of PKM2, phosphorylates and activates Erk1/2 signaling via PKM2, thereby promoting cell proliferation, including cancer cells[3-4].

In vitro, treatment of HeLa cells with SAICAR (0.5mM) for 30 minutes, SAICAR promotes phosphorylation of histone H3 and enhances c-Myc gene expression[5]. Under glucose deprivation conditions, exposure of HeLa, A549, U87, and H1299 cells to SAICAR (0–0.5mM) for 30 minutes. SAICAR promotes cancer cell survival under glucose-limited conditions while regulating glucose uptake and lactate production[6].

In vivo, SAICAR (100μM; 100μL) was topically injected into wounds of db/db diabetic mice once daily for 7 consecutive days. SAICAR significantly increased COL17 expression at the wound edge and the proportion of PCNA-positive proliferating epithelial cells, promoted wound re-epithelialization, accelerated wound closure, and improved delayed healing phenotypes[7].

Protokoll (Protocol)

Cell experiment [1]:

Cell lines

HeLa cells (human cervical cancer cell line), A549 (human lung cancer cell line), U87 (human glioblastoma cell line), and H1299 (non-small cell lung cancer cell line)

Preparation Method

HeLa cells were maintained in Dulbecco’s minimal essential medium (DMEM) supplemented with 10% dialyzed fetal bovine serum (FBS) at 37°C, 5% CO₂. Cells were subjected to glucose deprivation by incubation in glucose-free DMEM and treated with SAICAR (0–0.5mM) for 0.5 hours.

Reaction Conditions

0–0.5mM; 0.5h

Applications

SAICAR promoted the survival of cancer cells under glucose-limited conditions while regulating glucose uptake and lactate production.

Animal experiment [2]:

Animal models

C57BL/6J mice and C57BL/6J-db/db mice

Preparation Method

Mice were subjected to full-thickness excisional wounds (8mm diameter) on the dorsal skin. SAICAR (100μM in 100μL 0.9% saline) was topically injected around the wound edge once daily from post-wound day (PWD) 1 until tissue collection. Control groups received vehicle (0.9% saline with DMSO).

Dosage form

100μM; topical injection; daily for 7 days.

Applications

SAICAR treatment significantly accelerated wound closure and re-epithelialization in both normal and diabetic mice by promoting PKM2 nuclear translocation, STAT3 phosphorylation, and COL17 expression. SAICAR enhanced keratinocyte proliferation (increased PCNA-positive cells) and restored impaired healing in diabetic wounds, demonstrating therapeutic potential for chronic wound repair
