✦ Synopsis

During the adipose conversion of 3T3 cells, there occur sequential changes in cellular protein and mRNA composition. To determine if there are also changes in transcription, we have studied the transcripts of specific genes in isolated nuclei prepared before and after adipose conversion. Transcription of three genes encoding adipocyte-specific proteins was detectable only in adipocytes, whereas transcription of actin and collagen type I genes occurred in both adipocytes and preadipocytes. The activation of transcription of adipocyte-specific genes was not synchronous. Thus temporal differences in the appearance of different adipocyte mRNAs probably result from differences in the times of activation of transcription.

## Abstract The adipose conversion of cultured 3T3‐F442A cells is strongly inhibited if the fetal bovine serum of the culture medium is briefly acidified before it is used. The inhibitory factor is a polypeptide with an apparent molecular weight of 24,000, and is inactivated by pronase or trypsin.

We have found that the antibody A2, a marker for the capsule of steroidogenic lipid droplets, reacts with an intermediate filament-associated protein, P200, in 3T3-L1 preadipocytes. Supporting evidence came from the colocalization pattern of P200 with vimentin in double label experiments. The associ
