- 目标基因介绍: Lysophospholipid O-acyltransferase (LPLAT) that catalyzes the reacylation step of the phospholipid remodeling process also known as the Lands cycle (PubMed:18782225, PubMed:18195019, PubMed:18772128). Catalyzes transfer of the fatty acyl chain from fatty acyl-CoA to 1-acyl lysophospholipid to form various classes of phospholipids. Converts 1-acyl lysophosphatidylcholine (LPC) into phosphatidylcholine (PC) (LPCAT activity), 1-acyl lysophosphatidylserine (LPS) into phosphatidylserine (PS) (LPSAT activity) and 1-acyl lysophosphatidylethanolamine (LPE) into phosphatidylethanolamine (PE) (LPEAT activity) (PubMed:18782225, PubMed:18195019, PubMed:18772128). Favors polyunsaturated fatty acyl-CoAs as acyl donors compared to saturated fatty acyl-CoAs (PubMed:18195019, PubMed:18772128). Has higher activity for LPC acyl acceptors compared to LPEs and LPSs. Can also transfer the fatty acyl chain from fatty acyl-CoA to 1-O-alkyl lysophospholipid or 1-O-alkenyl lysophospholipid with lower efficiency (By similarity). Acts as a major LPC O-acyltransferase in liver and intestine. As a component of the liver X receptor/NR1H3 or NR1H2 signaling pathway, mainly catalyzes the incorporation of arachidonate into PCs of endoplasmic reticulum (ER) membranes, increasing membrane dynamics and enabling triacylglycerols transfer to nascent very low-density lipoprotein (VLDL) particles. Promotes processing of sterol regulatory protein SREBF1 in hepatocytes, likely by facilitating the translocation of SREBF1-SCAP complex from ER to the Golgi apparatus (By similarity). Participates in mechanisms by which the liver X receptor/NR1H3 or NR1H2 signaling pathway counteracts lipid-induced ER stress response and inflammation. Downregulates hepatic inflammation by limiting arachidonic acid availability for synthesis of inflammatory eicosanoids, such as prostaglandins (By similarity). In enterocytes, acts as a component of a gut-brain feedback loop that coordinates dietary lipid absorption and food intake. Regulates the abundance of PCs containing linoleate and arachidonate in enterocyte membranes, enabling passive diffusion of fatty acids and cholesterol across the membrane for efficient chylomicron assembly (By similarity). In the intestinal crypt, acts as a component of dietary-responsive phospholipid-cholesterol axis, regulating the biosynthesis of cholesterol and its mitogenic effects on intestinal stem cells (By similarity).
- 细胞开发路径: A stable KO cell line was generated using the CRISPR‑RNP approach; Sanger sequencing confirmed 100% knockout efficiency in the target locus.
- 应用: A gene-knockout cell line with high knockout efficiency, particularly well suited for preliminary functional analyses, the development of complex disease models, precision drug screening, and broad‑scale gene discovery studies.

01. Preheat the complete culture medium in a 37°C water bath.
02. Thaw the cryovial in a 37°C water bath for 1–2 minutes.
03. Transfer the cryovials into a biosafety cabinet and wipe their surfaces with 70% ethanol.
04. Unscrew the cap of the cryovial and gently transfer the cell suspension into a sterile centrifuge tube containing 9 mL of complete culture medium.
05. Centrifuge at room temperature at 125g for 5–7 minutes, then discard the supernatant.
06. Resuspend the cell pellet in 5 mL of complete culture medium, and transfer the cell suspension to a T25 culture flask.
07. Transfer the cells to a 37°C incubator with 5% CO2 for culture.
08. Recommended passage ratio: 1/2 to 1/4; cells reach confluence in 2–3 days. -
01. When the cells in the culture flask reach a confluence of 80%–90% or higher, cell passage can be performed.
02. Remove the culture medium, PBS, and trypsin (0.25% Trypsin‑EDTA, Gibco 25200‑056) from the 4°C refrigerator, place them in a 37°C water bath, and once their temperature approaches 37°C, take them out. Spray the exterior of the bottles with 75% ethanol, then transfer them to a biosafety cabinet.03. Remove the culture flask to be passaged from the incubator, spray the exterior of the flask with 75% ethanol, and place it inside a biosafety cabinet.
04. To avoid dispersing the cells, gently rinse the cells along the inner wall of the culture flask with PBS; discard the wash solution, and add 2 mL of PBS to the T25 flask.
05. Add the appropriate volume of trypsin (1.5 mL for a T75 flask, 0.5 mL for a T25 flask), and gently swirl the flask to ensure the enzyme evenly covers the cell‑covered bottom. Adjust the volume as needed based on the specific situation. After approximately 1–2 minutes, when most of the cells have detached, add the corresponding volume of complete culture medium to stop the digestion, then use a 5‑mL pipette to gently pipette up and down until all cells are fully detached.
06. Transfer the cell suspension to a 15 mL centrifuge tube, centrifuge at 300 × g for 5 minutes, and discard the supernatant.
07. Transfer 5 mL of complete culture medium to resuspend the cells, adjust the seeding ratio as needed, and replenish the culture flask with complete medium—add up to 13–15 mL for a T75 flask or 5 mL for a T25 flask—and supplement with 1% double antibiotic solution.
08. After capping the bottle and tightening the lid, gently shake the vial to ensure uniform mixing of the cells, then place it in a 37°C incubator with 5% CO2. -
01. Prepare the cryopreservation solution and pre-cool it in advance.
02. Ensure that the cells to be cryopreserved meet the cryopreservation requirements, and verify the following conditions under a microscope: healthy appearance and morphological characteristics, being in the late logarithmic growth phase, and showing no signs of contamination or senescence.
03. Digest and centrifuge the cells (refer to the subculture protocol for specific steps).
04. Resuspend the cells in cryopreservation medium at 1 mL per tube, gently pipette up and down to ensure uniformity, and then aliquot into cryovials.
05. Place the cells in a programmed cooling box and freeze them in a −80°C freezer.
06. Subsequently, the cells are transferred to a liquid nitrogen tank for long-term storage. - In antibody validation
