Table 4. Potential factors contributing to observation of somewhat different obese phenotype noted with “L-FABP null/GFP overexpressor” mice.

Differences were derived by comparisons of methodology reported for “L-FABP null/GFP overexpressor mice” [143, 163-165, 182, 197] with those for the original “L-FABP null mice” mice [45, 56, 59, 71, 98, 142, 152, 153, 162, 167, 176, 177]. Additional references in the table refer to other publications demonstrating such differences in factors/parameters can affect mouse phenotype/obesity/lipid metabolism.

	Peptide fragments?	Yes	[201-208, 208, 209, 209-215]
	GFP overexpression	Yes	[216-221]
Backcrossing	C57BL/J substrain more obesity susceptible	Yes	[222], http://jaxmice.jax.org/jaxnotes/511/511n.html
	Backcross generation number of L-FABP null	No	[98]
Control mice	Vendor supplied vs wild-type littermates	Yes
	Age	Yes	[223-225]
	Sex	Yes	[58, 169]
Diets	Vendor source, non-defined, not phytol free, not phytoestrogen free	Yes	[58, 168, 171, 172]
	Ad libitum feeding, length of time on high fat diet	Yes
