July 2:

• HepG2 cell passaging
• Made sodium palmitate from powder to solution by 50% Ethanol

July 3:

• Used GCMS to quantify the FA in the medium

July 4:

• Passaged HepG2 cells
• Changed medium for cell line
• Searched for information of MTT assay and Transfection by lipofectamine
• Got GCMS results for the last day: Not accurate/usable

July 5:

• Repeated GCMS test again testing FA in medium and we made
• Got the result of GCMS: Not accurate/usable

July 8:

• Passaged HepG2 cells
• Used some HepG2 cells to extract genomic DNA

July 9:

• Another try of GCMS with a gradient concentration of FA
• Got the result of GCMS: Not match with the concentration we made

July 10:

• Repeated GCMS: No accurate results
• Changed Medium for the cell line
• Checked lipofectamine protocol

July 11:

• GCMS again for the same sodium palmitate we made: Not accurate results
• Passaged HepG2 cell line

July 12:

• Prepared reagents for MTT assay for cell viability test, protocols checked
• Changed the medium of the cell line

July 15:

• Seeded HepG2 cells into 96-well plate for MTT cell viability test and adding FA
• Seeded HepG2 cells into 96-well plate for transfection of PEGFP-N1

July 16:

• Transfection of PEGFP-N1 into HepG2 cells
• Passaged HepG2 cells

July 17:

• Changed the medium after transfection had been done in 24 hours
• Did MTT assay and getting result (adding FA in the wrong time, cannot be used)
• Made new DMEM
• Changed medium for the cell line

July 18:

• Seeded HepG2 cells in 24-well plate for transfection of PEGFP-N1, PCMV/myc/mito/EGFP and PCMY/myc/mito/GFP
• Got polylysine for coating

July 19:

• Changed the medium for the HepG2 cell line
• Seeded cells for another MTT assay
• Checked HepG2 cells for transfection: growing slow, 30% confluency, cannot do transfection
• Seeded cells on a 96-well plate for transfection in the coming week
• Passaged HepG2 cells

July 22:

• Transfection of PEGFP-N1, PCMV/myc/mito/EGFP and PCMY/myc/mito/GFP on 96-well plate
• Added gradient concentration of sodium palmitate into HepG2 cells for MTT assay
• Coated coverslips with polylysine for HepG2 cell staining and fixation

July 23:

• Replaced the medium after transfection of PEGFP-N1, PCMV/myc/mito/EGFP and PCMY/myc/mito/GFP
• Finished MTT assay to get cell viability in different FA concentrations in 24 hours
• Transferredcells containing PEGFP-N1, PCMV/myc/mito/EGFP and PCMY/myc/mito/GFP into 24-well plate with well-coated coverslips in each well

July 24:

• Stained mitochondria by Mito-tracker@Red and fixating by formaldehyde of HepG2 cells transfected with PEGFP-N1, PCMV/myc/mito/EGFP and PCMY/myc/mito/GFP in 24-well plate
• Passaged HepG2 cells and changing medium of the cell line

July 25:

• Got results for cell staining and fixation: No obvious overlapping pattern between GPF signal and Mito-tracker red.

July 26:

• Coated coverslips by polylysine
• Seeded HepG2 cells in one 24-well plate for transfection of PEGFP-N1, PCMV/myc/mito/EGFP and PCMY/myc/mito/GFP
• Seeded HepG2 cells on two 96-well plate, for transfection of FABP and MTT assay in 48 hours

July 29:

• Transfection of FABP with PEGFP-N1 as control
• Transfection of PEGFP-N1, PCMV/myc/mito/EGFP and PCMY/myc/mito/GFP in 24-well plate with well-coated coverslips
• Added gradient concentration form 0.1mM to 1.2mM of FA into the plate for MTT assay

July 30:

• Changed medium after transfection of PEGFP-N1 and FABP and seeing the results: Both PEGFP-N1 and FABP did not show GFP signals
• Changed medium after transfection of PEGFP-N1, PCMV/myc/mito/EGFP and PCMY/myc/mito/GFP
• Did staining and fixation of the coverslips and seeing the results: No obvious overlapping patterns of GFP signals and Mito-tracker red
• Passaged HepG2 cells
